FT9Y-B1382(6)Ladder Programming ManualSAFETY PRECAUTIONS• Read the SmartAXIS Pro/Lite User’s Manual to make sure of correct operation before starting installation, wiring, operation, maintenance, andinspection of the SmartAXIS.
• All SmartAXIS modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe provision to thecontrol system when using the SmartAXIS in applications where heavy damage or personal injury may be caused in case the SmartAXIS shouldfail.
• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:

Warning

Warning notices are used to emphasize that improper operation may cause severe personal injury or death.

• The SmartAXIS is not designed for use in medical equipment, nuclear power, railways, aviation, passenger vehicle equipment, or similar

applications requiring a high degree of reliability and safety. The SmartAXIS cannot be used for such applications.
• When using the SmartAXIS in applications not described above that require a high degree of reliability in terms of functionality and precision,

appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for a system containing the SmartAXIS.
• Emergency stop and interlocking circuits must be configured outside the SmartAXIS.
• If relays or transistors in the SmartAXIS output circuits should fail, outputs may remain in the on or off state. For output signals which may

cause serious accidents, configure monitor circuits outside the SmartAXIS.
• The SmartAXIS self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits sothat the system containing the SmartAXIS is not jeopardized when outputs turn off.
• Turn off power to the SmartAXIS before installation, removal, wiring, maintenance, and inspection of the SmartAXIS. Failure to turn power off

may cause electrical shocks or fire hazard.
• Special expertise is required to install, wire, program, and operate the SmartAXIS. People without such expertise must not use the SmartAXIS.
• Install the SmartAXIS according to the instructions described in SmartAXIS Pro/Lite user's manual. Improper installation will result in falling,

failure, or malfunction of the SmartAXIS.

CautionCaution notices are used where inattention might cause personal injury or damage to equipment.

• The SmartAXIS is designed for installation in a cabinet. Do not install the SmartAXIS outside a cabinet.
• Install the SmartAXIS in environments described in SmartAXIS Pro/Lite user's manual. If the SmartAXIS is used in places where the SmartAXIS

is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks, then electricalshocks, fire hazard, or malfunction will result.
• The environment for using the SmartAXIS is “Pollution degree 2.” Use the SmartAXIS in environments of pollution degree 2 (according to IEC

60664-1).
• While moving or transporting prevent the SmartAXIS from falling, otherwise damage or malfunction of the SmartAXIS will result.
• Wiring must use lead sizes that are appropriate for the applied voltage and current. Terminal screws must be tightened with the prescribedtightening torque.
• Prevent metal fragments and pieces of wire from dropping inside the SmartAXIS housing. Put a cover on the SmartAXIS modules during

installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
• Use a power supply of the rated value. Use of the wrong power supply may cause fire hazard.
• Use an IEC 60127-approved fuse on the power line outside the SmartAXIS. This is required when equipment containing the SmartAXIS isdesigned for use in Europe.
• Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the SmartAXIS is designed for use in Europe.
• Use an EU-approved circuit breaker. This is required when equipment containing the SmartAXIS is destined for Europe.
• Make sure of safety before starting and stopping the SmartAXIS or when operating the SmartAXIS to force outputs on or off. Incorrect operationof the SmartAXIS may cause machine damage or accidents.
• Do not connect the ground wire directly to the SmartAXIS. Connect a protective ground to the cabinet containing the SmartAXIS using an M4 orlarger screw. This is required when equipment containing the SmartAXIS is designed for use in Europe.
• Do not disassemble, repair, or modify the SmartAXIS modules.
• The SmartAXIS contains electronic parts and batteries. When disposing of the SmartAXIS, do so in accordancewith national and local regulations.

Note: Monitoring ladder program of FT1A Touch using WindLDR
You can monitor ladder programs and change device values of FT1A Touch using WindLDR. There is a limitation when you use bit devices out of thecontrol devices as 16-/32-bit data and change its device values.
When you monitor bit devices, such as internal relays or shift registers, you can monitor values of those bit devices starting from any addresses.
However, when you change values of those devices, device addresses must be 16-bit aligned. For example, you can change 16-/32-bit values ofinternal relays starting with M0000, M0020, or M1180, but values of internal relays starting with M0007, M0037, or M1181 cannot be changed.
When unaligned bit devices are entered in the Custom Monitor dialog box of WindLDR to monitor 16-/32-bit values, monitored values are shown ingrayed cell and you cannot change values of those devices.

3: DEVICE ADDRESSES
Introduction
This chapter describes device addresses available for the SmartAXIS Pro/Lite to program basic and advanced instructions. Special
internal relays and special data registers are also described. For details on the device addresses of SmartAXIS Touch, see Chapter
27 "Internal Devices" in the SmartAXIS Touch User's Manual.
The SmartAXIS is programmed using devices such as inputs, outputs, remote inputs, remote outputs, internal relays, timers,
counters, shift registers, and data registers.
Inputs (I) are relays to receive input signals through the input terminals.
Remote inputs (I) are relays to receive input signals from external devices connected to the remote I/O slaves.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Remote outputs (O) are relays to send output signals to external devices connected to the remote I/O slaves.
Internal relays (M) are relays used in the CPU and cannot be output to the output terminals.
Special internal relays (M) are internal relays dedicated to specific functions.
Timers (T) are relays used in the user program, available as 1-sec, 100-ms, 10-ms, and 1-ms timers.
Counters (C) are relays used in the user program, available as adding counters and reversible counters.
Shift registers (R) are registers to shift the data bits according to pulse inputs.
Data registers (D) are registers used to store numerical data.
Special data registers (D) are dedicated to special functions.

Device Addresses
Available I/O numbers depend on the SmartAXIS type.

Specifies the quantity of repeat cycles: 1 through 99.

OpcodeThe opcode is a symbol used to identify the advanced instruction.
Data TypeSpecifies word (W), integer (I), double word (D), long (L), or float(F) data.
Source Device
The source device specifies the 16- or 32-bit data to be processedby the advanced instruction. Some advanced instructions require
two source devices.
Destination Device
The destination device specifies the 16- or 32-bit data to store theresult of the advanced instruction. Some advanced instructions
require two destination devices.

Input Condition for Advanced Instructions
Almost all advanced instructions must be preceded by a contact, except NOP (no operation), LABEL (label), and LRET (label
return) instructions. The input condition can be programmed using a bit device such as input, output, internal relay, or shift
register. Timer and counter can also be used as an input condition to turn on the contact when the timer times out or the countercounts out.
While the input condition is on, the advanced instruction is
executed in each scan. To execute the advanced instruction
only at the rising or falling edge of the input, use the SOTU or
SOTD instruction.

While the input condition is off, the advanced instruction is not executed and device statuses are held.

Source and Destination Devices
The source and destination devices specify 16- or 32-bit data, depending on the selected data type. When a bit device such as
input, output, internal relay, or shift register is designated as a source or destination device, 16 or 32 points starting with thedesignated number are processed as source or destination data. When a word device such as timer or counter is designated as asource device, the current value is read as source data. When a timer or counter is designated as a destination device, the resultof the advanced instruction is set to the preset value for the timer or counter. When a data register is designated as a source ordestination device, the data is read from or written to the designated data register.

Using Timer or Counter as Source Device
Since all timer instructions—TML (1-sec timer), TIM (100-ms timer), TMH (10-ms timer), and TMS (1-ms timer)—subtract fromthe preset value, the current value is decremented from the preset value and indicates the remaining time. As described above,
when a timer is designated as a source device of an advanced instruction, the current value, or the remaining time, of the timer isread as source data. Adding counters CNT start counting at 0, and the current value is incremented up to the preset value.
Reversible counters CDP and CUD start counting at the preset value and the current value is incremented or decremented from thepreset value. When any counter is designated as a source device of an advanced instruction, the current value is read as source
data.

Using Timer or Counter as Destination Device
As described above, when a timer or counter is designated as a destination device of an advanced instruction, the result of theadvanced instruction is set to the preset value of the timer or counter. Timer and counter preset values can be 0 through 65535.
When a timer or counter preset value is designated using a data register, the timer or counter cannot be designated as adestination of an advanced instruction. When executing such an advanced instruction, a user program execution error will result.
For details of user program execution error, see Chapter 14 "Troubleshooting" - "User Program Execution Error" in the SmartAXIS
Pro/Lite User's Manual.
Note: When a user program execution error occurs, the result is not set to the destination.

Floating-Point Data Format
The SmartAXIS can specify floating-point data (F) for advanced instructions. Like double word (D) and long integer (L) data,
floating-point data also uses two consecutive data registers to execute advanced instructions. The SmartAXIS supports thefloating-point data based on the single storage format of the IEEE (The Institute of Electrical and Electronics Engineers) Standard
754.
Single Storage Format
The IEEE single storage format consists of three fields: a 23-bit fraction, f; an 8-bit biased exponent, e; and 1-bit sign, s. These
fields are stored contiguously in one 32-bit word, as shown in the figure below. Bits 0:22 contain the 23-bit fraction, f, with bit 0
being the least significant bit of the fraction and bit 22 being the most significant; bits 23:30 contain the 8-bit biased exponent, e,with bit 23 being the least significant bit of the biased exponent and bit 30 being the most significant; and the highest-order bit 31
contains the sign bit, s.

23 22

The table below shows the correspondence between the values of the three constituent fields s, e, and f and the value represented
by the single storage format bit pattern. When any value out of the bit pattern is entered to the advanced instruction or when
execution of advanced instructions, such as division by zero, has produced any value out of the bit pattern, a user program
execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.

User Program Execution Errors
When an advanced instruction is executed, a user program execution error occurs when any of the following conditions are met.
• the result of the adavnced instruction is invalid• source or destination device that is indirectly specified in the advanced instruction exceeds the valid device range• the advanced instruction does not operate correctly

For example, the data in the source device does not comply with the normal floating-point format when the data type is Float (F).
When a user program execution error occurs, special internal relay M8004 turns on and the corresponding error code is stored in
special data register D8006. For details about the error codes, see Chapter 14 “Troubleshooting” – “User Program Execution Error”
in the SmartAXIS Pro/Lite User’s Manual.
When a user program execution error occurs, instructions operate as follows:• When the source data is invalid, the execution of the advanced instruction is canceled and the data in the destination device is not changed.
• When the execution result is invalid, a value is stored in the destination device.

For details on stored values, see the descriptions of relevant instructions.
• If a user program execution error occurred during a repeat operation, the operation is canceled and the next repeat operation is executed.

M8004 is retained even when no further user program execution errors occur during subsequent repeat operations.

Example: User program execution error during a repeat operation
When the source data does not comply with the normal floating-point format.
When the second repeat operation is executed, special internal relay M8004 turns on because the source data is not a normal
number in floating-point format.
The second repeat operation is canceled and the third repeat operation is executed.

For details on overflow and underflow, see "Carry and Borrow in Floating-Point Data Processing" onpage 4-11.

When a carry or borrow occurs, special internal relay M8003 (carry and borrow) turns on.
For example, when D0 has a value of FFFF (hex) and +1 is added using an INC instruction, the result is 10000 (hex), but when thedata type is Word (W), 0000 (hex) is stored in D0 and 1 is stored in M8003.

Discontinuity of Device Areas
Each device area is discrete and does not continue, for example, from input to output or from output to internal relay. In addition,
special internal relays M8000 through M8177 are in a separate area from internal relays M0 through M1277. Data registers D0
through D999, non-retentive data registers D1000 through D1999, and special data registers D8000 through D8199 are in
separate areas and do not continue with each other.

The internal relay ends at M1277. Since the MOV (move) instruction reads 16 internal
relays, the last internal relay exceeds the valid range, resulting in a user program
syntax error.

REP

This program results in a user program syntax error. The destination of theDIV (division) instruction requires two data registers D999 and D1000. Since
D1000 exceeds the valid range, a user program syntax error occurs.

Advanced instructions execute operation only on the available devices in the valid area. If a user program syntax error is foundduring programming, WindLDR rejects the program instruction and shows an error message.

16 internal relays M1280 through M1297, which are invalid, resulting in a user program
syntax error.
For details about repeat operations of each advanced instruction, see the following
chapters.

NOP (No Operation)
No operation is executed by the NOP instruction.
NOPThe NOP instruction may serve as a place holder. It can also be used to add a delay to the CPU scan time, in order tosimulate communication with a machine or application, for debugging purposes.

Programming multiple outputs of the same output number is not recommended. However,
if doing so, it is good practice to separate the outputs with the JMP/JEND set of

• Countdown from the preset value is initiated when the operation result directly before the timer input is on.
• The timer output turns on when the current value (timed value) reaches 0.
• The current value returns to the preset value when the timer input is off.
• Timer preset and current values can be changed using WindLDR without downloading the entire program to the CPU again. From the

WindLDR menu bar, select Online > Monitor > Monitor, then Online > Custom > New Custom Monitor.
• If a timer preset value is changed during countdown, the timer remains unchanged for that cycle. The change will be reflected in the nexttime cycle.
• If a timer preset value is changed to 0, then the timer stops operation, and the timer output is turned on immediately.
• If a current value is changed during countdown, the change becomes effective immediately.
• For data movement when changing, confirming, and clearing preset values, see "Changing, Confirming, and Clearing Preset Values for Timers

and Counters" on page 5-17. Preset values can also be changed and confirmed using the LCD screen and pushbuttons.
• WindLDR ladder diagrams show TP (timer preset value) and TC (timer current value) in advanced instruction devices.
• The timer instructions (TML, TIM, TMH, TMS) and off-delay timer instructions (TMLO, TIMO, TMHO, TMSO) cannot be used in an interrupt

program.
• If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details

about the user program execution errors, see "User Program Execution Errors" on page 4-13.

Timer Accuracy
Timer accuracy due to software configuration depends on three factors: timer input error, timer counting error, and timeout output
error. These errors are not constant but vary with the user program and other causes.
Timer Input Error
The input status is read at the END processing and stored to the input RAM. So, an error occurs depending on the timing when thetimer input turns on in a scan cycle. The same error occurs on normal input and catch input. The timer input error shown below
does not include input delay caused by the hardware.

Timer Counting Error
Every timer instruction operation is individually based on asynchronous 16-bit reference timers. Therefore, an error can occur
depending on the status of the asynchronous 16-bit timer when the timer instruction is executed. Use of a TMS (1-ms timer) is
recommended to reduce advance errors.

The timer input error and timeout output error shown above do not include the input response time (behind error) and output responsetime (behind error) caused by hardware.

Power Failure Memory Protection
Timers TML, TIM, TMH, and TMS do not have power failure protection. To provide a timer with this protection use a counter
instruction and special internal relay M8121 (1-sec clock), M8122 (100-ms clock), or M8123 (10-ms clock).

Counter Operation after Count out
Condition

Counter Output

When the counter has counted out, either the current value or preset
value is changed.

The counter maintains the counted out status.

Before the counter has counted out, the current value is changed to alarger value than the preset.

The counter output is turned on.

The preset value is changed to 0.

The counter output is turned on without regard to the current value.

When the reset input is on, the preset value is changed to 0.

The counter output is not turned on.

5: BASIC INSTRUCTIONSCUD (Up/Down Selection Reversible Counter)
The up/down selection reversible counter CUD has a selection input to switch the up/down gate, so the three inputs are required.
The circuit for an up/down selection reversible counter must be programmed in the following order: preset input, pulse input, up/
down selection input, the CUD instruction, and a counter number C0 through C199, followed by a counter preset value from 0 to
65535.
The preset value can be designated using a decimal constant or a data register. When a data register is used, the data of the dataregister becomes the preset value.

CNTD, CDPD, and CUDD (Double-Word Counter)
Three types of double-word counters are available; adding (up) counter CNTD, dual-pulse reversible counter CDPD, and up/down
selection reversible counter CUDD. A total of 50 (FT1A-12) or 100 (other SmartAXIS) double-word counters can be programmed ina user program. Each double-word counter uses 2 consecutive devices starting with the allocated device, which can be C0 throughC198. Once used in a user program, counters cannot be used in any other counter instructions.

CNTD (Double-Word Adding Counter)
When double-word adding counter instructions are programmed, two addresses are required. The circuit for a double-word adding(UP) counter must be programmed in the following order: reset input, pulse input, the CNTD instruction, and a counter number C0
through C198, followed by a counter preset value from 0 to 4,294,967,295.
The preset value can be designated using a constant or a data register. When a data register is used, the double-word data of twoconsecutive data registers becomes the preset value. For 32-bit data storage setting, see Chapter 5 "Special Functions" - "32-bit

5: BASIC INSTRUCTIONSSFR and SFRN (Forward and Reverse Shift Register)
SmartAXIS have a shift register consisting of 128 bits which are allocated to R0 through R127. Any number of available bits can beselected to form a train of bits which store on or off status. The on/off data of constituent bits is shifted in the forward direction(forward shift register) or in the reverse direction (reverse shift register) when a pulse input is turned on.

Forward Shift Register (SFR)
When SFR instructions are programmed, two addresses are always required. The SFR instruction is entered, followed by a shift
register number selected from appropriate device addresses. The shift register number corresponds to the first, or head bit. The
number of bits is the second required address after the SFR instruction.
The SFR instruction requires three inputs. The forward shift register circuit must be programmed in the following order: reset
input, pulse input, data input, and the SFR instruction, followed by the first bit and the number of bits.

Reset Input
The reset input will cause the value of each bit of the shift register to return to zero. Initialize pulse special internal relay, M8120,
may be used to initialize the shift register at start-up.
Pulse Input
The pulse input triggers the data to shift. The shift is in the forward direction for a forward shift register and in reverse for areverse shift register. A data shift will occur upon the leading edge of a pulse; that is, when the pulse turns on. If the pulse has
been on and stays on, no data shift will occur.
Data Input
The data input is the information which is shifted into the first bit when a forward data shift occurs, or into the last bit when areverse data shift occurs.
Note: When power is turned off, the statuses of all shift register bits are normally cleared. It is also possible to maintain the statuses of shift
register bits by using the Function Area Settings as required. See Chapter 5 "Special Functions" - "Keep Designation for Internal Relays, Shift
Registers, Counters, and Data Registers" in the SmartAXIS Pro/Lite User's Manual.
Note: The SFR instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal
relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page4-13.

Note: For restrictions on ladder programming of shift register instructions, see "Restriction on Ladder Programming" on page 5-31.

5: BASIC INSTRUCTIONSSOTU and SOTD (Single Output Up and Down)
The SOTU instruction “looks for” the transition of a given input from off to on. The SOTD instruction looks for the transition of agiven input from on to off. When this transition occurs, the desired output will turn on for the length of one scan. The SOTU or
SOTD instruction converts an input signal to a “one-shot” pulse signal.
A total of 1024 SOTU and SOTD instructions can be used in a user program.
If operation is started while the given input is already on, the SOTU output will not turn on. The transition from off to on is what
triggers the SOTU instruction.
The SOTU or SOTD instructions cannot be used in an interrupt program.
If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For
details about the user program execution errors, see "User Program Execution Errors" on page 4-13.
When a CPU relay is defined as the SOTU or SOTD output, it may not operate if the scan time is not compatible with relay
requirements.

The MCS (master control set) instruction is usually used in combination with the MCR (master control reset) instruction. The MCS
instruction can also be used with the END instruction, instead of the MCR instruction.
When the input preceding the MCS instruction is off, the MCS is executed so that all inputs to the portion between the MCS and the

is executed according to the actual input statuses.
When the input condition to the MCS instruction is off and the MCS is executed, other instructions between the MCS and MCR are
executed as follows:

END
The END instruction is always required at the end of a program; however, it is not necessary to program the END instruction after
the last programmed instruction. WindLDR automatically appends the END instruction at the end of a program.
A scan is the execution of all instructions from address zero to the END instruction. The time required for this execution is referred
to as one scan time. The scan time varies with respect to program length, which corresponds to the address where the END
instruction is found.
During the scan time, program instructions are processed sequentially. This is why the output instruction closest to the END
instruction has priority over a previous instruction for the same output. No output is initiated until all logic within a scan isprocessed.
Output occurs simultaneously, and this is the first part of the END instruction execution. The second part of the END instruction
execution is to monitor all inputs, also done simultaneously. Then program instructions are ready to be processed sequentiallyonce again.

6: MOVE INSTRUCTIONSIntroduction
Data can be moved using the MOV (move), MOVN (move not), IMOV (indirect move), or IMOVN (indirect move not) instruction.
The moved data is 16- or 32-bit data, and the repeat operation can also be used to increase the quantity of data moved. In the
MOV or MOVN instruction, the source and destination device are designated by S1 and D1 directly. In the IMOV or IMOVN
instruction, the source and destination device are determined by the offset values designated by S2 and D2 added to source device
S1 and destination device D1.
The BMOV (block move) instruction is useful to move consecutive blocks of timer, counter, and data register values.
The IBMV (indirect bit move) and IBMVN (indirect bit move not) instructions move one bit of data from a source device to a
destination device. Both devices are determined by adding an offset to the device.
NSET (N data set) and NRS (N data repeat set) instructions can be used to set values to a group of devices. The XCHG (exchange)
instruction is used to swap word or double-word data between two devices. The current timer or counter values can be changed
using the TCCST (timer/counter current value store) instruction.
Since the move instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be
used.

Repeat Bit Devices
The MOV (move) instruction moves 16-bit data (word or integer data) or 32-bit data (double-word or integer data). When a bit
device such as input, output, internal relay, or shift register is designated as the source or destination device, 16 or 32 bits startingwith the one designated by S1 or D1 are the target data. If a repeat operation is designated for a bit device, the target data
increases in 16- or 32-bit increments, depending on the selected data type.

7: DATA COMPARISON INSTRUCTIONSIntroduction
Data can be compared using data comparison instructions, such as equal to, unequal to, less than, greater than, less than or equal
to, and greater than or equal to. When the comparison result is true, an output or internal relay is turned on. The repeat operation
can also be used to compare more than one set of data.
When the repeat operation is enabled, repeated comparison results of CMP instructions can be selected from AND or OR operation,and the result is outputted to an output or internal relay.
Three values can also be compared using the ICMP>= instruction.
Load comparison instructions load comparison results so that the following instructions can be initiated.
Since the data comparison instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction
should be used.

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the source,
16 points (word or integer data) or 32 points (double-word or long data) are used. When repeat is assigned for a
bit device, the quantity of device bits increases in 16- or 32-point increments.
When a word device such as T (timer), C (counter), or D (data register) is assigned as the source, 1 point (wordor integer data) or 2 points (double-word, long, or float data) are used. When repeat is assigned for a word
device, the quantity of device words increases in 1- or 2-point increments.
When an output or internal relay is assigned as the destination, only 1 point is used regardless of the selected
data type. When repeat is assigned for the destination, outputs or internal relays as many as the repeat cycles
are used.

Special Internal Relays M8150, M8151, and M8152 in CMP=
Three special internal relays are available to indicate the comparison result of the CMP= instruction. Depending on the result, oneof the three special internal relays turns on.
When S1 > S2, M8150 turns on.
When S1 = S2, M8151 turns on.
When S1 < S2, M8152 turns on.

Repeat Operation in the Data Comparison Instructions
The following examples use the CMP≥ instruction of word and double word data. Repeat operation for all other data comparison
instructions and other data types is the same as the following examples.
When the repeat operation is enabled, repeated comparison results of CMP instructions can be selected from AND or OR operation,and the result is output to an output or internal relay.
Repeat One Source Device
When only S1 (source) is designated to repeat, source devices (as many as the repeat cycles, starting with the device designatedby S1) are compared with the device designated by S2. The comparison results are ANDed or ORed and set to the destination

Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S1 or S2, the timer/counter current value (TC or CC) is displayed. When T (timer) or C (counter) is used as
D1, the data is written in as a preset value (TP or CP) which can be 0 through 65535.
When F (float) data is selected, only data register and constant can be designated as S1 and S2.
When F (float) data is selected and S1 or S2 does not comply with the normal floating-point format, a user program execution error will result,
turning on special internal relay M8004 and ERR LED on the SmartAXIS. For user program execution errors, see "User Program Execution Errors" onpage 4-13.

8: BINARY ARITHMETIC INSTRUCTIONS
Repeat Operation in the DIV Instruction
Since the DIV (division) instruction (except float data) uses two destination devices, the quotient and remainder are stored as
described below. Source devices S1 and S2 and destination device D1 can be assigned to repeat individually or in combination.
When destination device D1 is not assigned to repeat, the final result is set to destination device D1 (quotient) and D1+1
(remainder). When repeat is assigned, assigned as many consecutive devices as the repeat cycles starting with the designateddevice are used.
Division instructions in float data do not generate remainders and use two consecutive data registers to store quotients. When
repeat is assigned for destination of float data, as many consecutive data registers as the repeat cycles are used.

Internal relays M0 through M1277 can be assigned as D1. Special internal relays cannot be assigned as D1.
When T (timer) or C (counter) is used as S1 or S2, the timer/counter current value (TC or CC) is displayed. When T (timer) or C (counter) is used as
D1, the data is written in as a preset value (TP or CP) which can be 0 through 65535.
Since the Boolean computation instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be
used.

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the sourceor destination, 16 points (word data) or 32 points (double-word data) are used. When repeat is assigned for a bit
device, the quantity of device bits increases in 16- or 32-point increments.
When a word device such as T (timer), C (counter), or D (data register) is assigned as the source or destination,
1 point (word data) or 2 points (double-word data) are used. When repeat is assigned for a word device, thequantity of device words increases in 1- or 2-point increments.

Example: XORW
To convert optional output status among a series of 10 output points, use the XORW instruction in combination with 10 internal
relay points.

Repeat Operation in the ANDW, ORW, and XORW Instructions
Source devices S1 and S2 and destination device D1 can be assigned to repeat individually or in combination. When destination
device D1 is not designated set to repeat, the final result is set to destination device D1. When repeat is assigned, consecutive
devices as many as the repeat cycles starting with the designated device are used. Since the repeat operation works similarly on
the ANDW (AND word), ORW (OR word), and XORW (exclusive OR word) instructions, the following examples use the ANDW
instruction.

Bit shift instructions are used to shift the data string starting with source device S1 to the left or right by 1 to 15 bits as designated.
The data string can be 1 to 65535 bits. The result is set to the source device S1 and special internal relay M8003 (carry or borrow).
The LSB or MSB is filled with 0 or 1 as designated.
Bit shift and rotate instructions are used to shift the 16- or 32-bit data string in the designated source device S1 to the left or rightby the quantity of bits designated. The result is set to the source device S1 and special internal relay M8003 (carry or borrow).
The BCD left shift instruction shifts the BCD digits in two consecutive data registers to the left.
The word shift instruction is used to move 16-bit data to a destination data register and shifts down the data of subsequent dataregisters as many as designated.

When T (timer) or C (counter) is used as S2, the timer/counter current value (TC or CC) is displayed.
The number of digits that can be shifted as S2 are 1 through 7.
Make sure that the source data determined by S1 and S1+1 is between 0 and 9999 for each data register. If either source data is over 9999, a user
program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. When S2 is higher than 7, a user
program execution error will also result.
When a user program execution error occurs, the execution of the instruction is canceled. The data in S1 and S1+1 is left unchanged and the next
instruction is executed. For user program execution errors, see "User Program Execution Errors" on page 4-13.

Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S2, the timer/counter current value (TC or CC) is displayed. When T (timer) or C (counter) is used as D1,
the data is written in as a preset value (TP or CP) which can be 0 through 65535.
Valid values for S2 to designate as the number of bits that can be searched is 1 through 256. Make sure that the search area designated by S1 plus
S2 is within the valid value range. If the source data exceeds the valid range, a user program execution error will result, turning on special internal
relay M8004 and the ERR LED on the SmartAXIS.
When a user program execution error occurs, the execution of the instruction is canceled. The value of D1 is left unchanged and the next instruction
is executed. For user program execution errors, see "User Program Execution Errors" on page 4-13.

For example, if pulse output is disabled and the ON settings are Monday 13:00 and the OFF settings are Wednesday 18:00, output
D1 turns on and off as follows.
When the WEEK instruction input is ON on Monday 13:00, output D1 turns ON on Monday 13:00 and it turns OFF on Wednesday

The YEAR instruction compares the specified date with the current date andoutputs that result. With this instruction you can specify special dates within a
one year period.
When the input is on, the output specified by D1 is turned on when the datespecified by the ON settings matches the current date.
The output is turned off when the date specified by the OFF settings matches thecurrent date.
When the ON settings are December 15, 2012 and the OFF settings are January

Notes:• A maximum of 10 YEAR instructions can be used in a user program.
• Normally the output is only updated when the current date and the date for the ON/OFF settings matches, but when the YEAR instruction

input changes from off to on, the output state at the current date is determined according to the ON/OFF settings and the output is turned on
or off.
For details, see "Timing Chart when the Input Turns On during the Configured Interval" on page 12-22.
• When pulse output is enabled, output is turned on for one scan at the instant (0:00) the date changes to the ON date.

When the YEAR instruction input changes from off to on, the output state at the current date is judged according to the ON/OFF settings, andthe output is turned on for 1 scan only.
For pulse output, see "6. Pulse Output" on page 12-14 or "6. Pulse Output" on page 12-18.
• When the year data is outside the range of 2000 to 2099, the month data is outside the range of 1 to 12, the day data is outside the range of

1 to 31, the week data is outside the range of 1 to 5, and the day of the week data is outside the range of 0 to 6, a user program execution
error will occur.
• The YEAR instruction cannot be used in an interrupt program.

If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details
about the user program execution errors, see "User Program Execution Errors" on page 4-13.
• When the yearly setting or monthly setting is enabled and a date that does not exist according to the month or year is set for the ON settingor the OFF setting, the output turns on or off on the first day of the next month.

Floating Point Value Notation on LCD

The SmartAXIS Pro system software version 2.21 or later supports decimal and exponent notations for the floating-pointvalues displayed on LCD. The notation depends on the value to display. Whether or not to use decimal notation or exponent
notation is determined according to the single-precision floating point definition in IEEE 754 and the internal system function
included in the SmartAXIS Pro.
The IEEE 754 single precision format consists of three fields: a 23-bit fraction, f; an 8-bit biased exponent, e; and 1-bit sign,s. These fields are stored contiguously in one 32-bit word, as shown in the figure below. Bits 0:22 contain the 23-bit fraction,f, with bit 0 being the least significant bit of the fraction and bit 22 being the most significant; bits 23:30 contain the 8-bit
biased exponent, e, with bit 23 being the least significant bit of the biased exponent and bit 30 being the most significant;and the highest-order bit 31 contains the sign bit, s.

The table below shows the correspondence between the values of the three constituent fields s, e, and f and the value
represented by the single precision format bit pattern.
When the value is ±0, denormalized number, or normalized number, the value is displayed according to the internal system
function of the SmartAXIS Pro.

SMARTAXIS LADDER PROGRAMMING MANUAL FT9Y-B1382

14: PROGRAM BRANCHING INSTRUCTIONSIntroduction
The program branching instructions reduce execution time by making it possible to bypass portions of the program whenevercertain conditions are not satisfied.
The basic program branching instructions are LABEL and LJMP, which are used to tag an address and jump to the address which
has been tagged. Programming tools include “either/or” options between numerous portions of a program and the ability to callone of several subroutines which return execution to where the normal program stopped.

LABEL (Label)This is the label number, from 0 to 255, used at the program address where the execution of program instructions
begins for a program branch.

LABEL
***

An END instruction may be used to separate a tagged portion of the program from the main program. In this way, scantime is minimized by not executing the program branch unless input conditions are satisfied.
Note: A single label number cannot be used more than once.

When input is on, jump to the address with label 0 through 255 assigned by S1.

*****

When input is off, no jump takes place, and program execution proceeds with the next instruction.
The LJMP instruction is used as an “either/or” choice between two portions of a program. Program
execution does not return to the instruction following the LJMP instruction, after the program branch.

For valid device address ranges, see "Device Addresses" on page 3-1.
Since the LJMP instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.
Note: Make sure that a LABEL instruction of the label number used for a LJMP instruction is programmed. When designating S1 using other than aconstant, the value for the label is a variable. When using a variable for a label, make sure that all probable LABEL numbers are included in the user

Using the Timer Instruction with Program Branching
When the timer start input of the TML, TIM, TMH or TMS instruction is already on, countdown begins immediately at the location
jumped to, starting with the timer current value. When using a program branch, it is important to make sure that timers are
initialized when desired, after the jump. If it is necessary to initialize the timer instruction (set to the preset value) after the jump,
the timer’s start input should be kept off for one or more scan cycles before initialization. Otherwise, the timer input on will not berecognized.

Using the SOTU/SOTD Instructions with Program Branching
Check that pulse inputs of counters and shift registers, and inputs of single outputs (SOTU and SOTD) are maintained during thejump, if required. Hold the input off for one or more scan cycles after the jump for the rising or falling edge transition to berecognized.

*****

When input is on, the address with label 0 through 255 assigned by S1 is called. When input is off, no calltakes place, and program execution proceeds with the next instruction.
The LCAL instruction calls a subroutine, and returns to the main program after the branch is executed. A
LRET instruction (see below) must be placed at the end of a program branch which is called, so that normal
program execution resumes by returning to the instruction following the LCAL instruction.
Note: The END instruction must be used to separate the main program from any subroutines called by the
LCAL instruction.
A maximum of four LCAL instructions can be nested. When more than four LCAL instructions are nested, auser program execution error will result, turning on special internal relay M8004 and the ERR LED on the
SmartAXIS.

15: REFRESH INSTRUCTIONSIntroduction
This chapter describes the refresh instructions that update the status of input contacts, external output , and the current value ofthe high-speed counter, to the latest value during a ladder scan.

IOREF (I/O Refresh)
IOREF

When input is on, 1-bit I/O data assigned by source device S1 is refreshed immediately regardless of thescan time.

S1
*****

When I (input) is used as S1, the actual input status is immediately read into an internal relay starting with
M300 allocated to each input available on the SmartAXIS.
When Q (output) is used as S1, the output data in the RAM is immediately written to the actual output
available on the SmartAXIS.
Refresh instructions are useful when a real-time response is required in a user program which has a longscan time. The refresh instruction is most effective when using the refresh instruction at a ladder step
immediately before using the data.
The IOREF instruction can be used with an interrupt input or timer interrupt to refresh data.

During normal execution of a user program, I/O statuses are refreshed simultaneously when the END instruction is executed at theend of a scan. When a real-time response is needed to execute an interrupt, the IOREF instruction can be used. When the input tothe IOREF instruction is turned on, the status of the designated input or output is read or written immediately.
When the IOREF instruction is executed for an input, the filter does not take effect and the input status at the moment is read toa corresponding internal relay.
The actual input status of the same input number is read to the internal input memory when the END instruction is executed as in
the normal scanning, then the filter value has effect as designated in the Function Area Settings. See Chapter 5 "Special Functions"- "Input Filter" in the SmartAXIS Pro/Lite User's Manual.

Interrupt inputs I0 through I7 and timer interrupt selected in the Function Area Settings are normally enabled when the CPU starts. When the DI
instruction is executed, interrupt inputs and timer interrupt designated as source device S1 are disabled even if the interrupt condition is met in theuser program area subsequent to the DI instruction. When the EI instruction is executed, disabled interrupt inputs and timer interrupt designated assource device S1 are enabled again in the user program area subsequent to the EI instruction. Different interrupts can be selected for the DI and EI
instructions to disable and enable interrupt inputs selectively. For Interrupt Input and Timer Interrupt, see Chapter 5 "Special Functions" - "Interrupt
Input" and "Timer Interrupt" in the SmartAXIS Pro/Lite User's Manual.
Make sure that interrupt inputs and timer interrupt designated as source device S1 are selected in the Function Area Settings. Otherwise, when the
DI or EI instruction is executed, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the
SmartAXIS.
The DI and EI instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal

The following example demonstrates setting up two coordinate points to define the linear relationship between X and Y. The twopoints are (X0, Y0) = (0, 0) and (X1, Y1) = (8000, 4000). Once these are set, there is an X to Y conversion, as well as a Y to X
conversion.

17: COORDINATE CONVERSION INSTRUCTIONS
Example: Overlapping Coordinates
In this example, the XYFS instruction sets up three coordinate points, which define two different linear relationships between X
and Y. The three points are: (X0, Y0) = (0, 100), (X1, Y1) = (100, 0), and (X2, Y2) = (300, 100). The two line segments define
overlapping coordinates for X. That is, for each value of Y within the designated range, there would be two X values assigned.

The first line segment defines the following relationship for X to Y conversion:
Y = – X + 100
The second line segment defines another relationship for X to Y conversion:
1
Y = --- X – 50
2
For X to Y conversion, each value of X has only one corresponding value for Y. If the current value of counter C10 is 250, the value assigned to D90
is 75.
For Y to X conversion, the XYFS instruction assigns two possible values of X for each value of Y. The relationship defined by the first two points has
priority in these cases. The line between points (X0, Y0) and (X1, Y1), that is, the line between (0, 100) and (100, 0), has priority in defining therelationship for Y to X conversion (X = –Y + 100).
Therefore, if the value in data register D95 is 40, the value assigned to D30 is 60, not 180.
Exactly the same two line segments might also be defined by the XYFS instruction, except that the point (300, 100) could be assigned first, as (X0,
Y0), and the point (100, 0) could be defined next, as (X1, Y1). In this case, this linear relationship would have priority.
In this case, if the value in data register D95 is 40, the value assigned to D30 is 180, not 60.

While input is on, the AVRG instruction is executed in each scan. When the quantity of sampling cycles (scan times) designated by device S3 is 1
through 65535, sampling data designated by device S1 is processed in each scan. When the designated sampling cycles have been completed, theaverage value of the sampling data is set to the device designated by D1 (data type W or I) or D1·D1+1 (data type D, L, or F). The maximum valueof the sampling data is set to the next device, D1+1 (data type W or I) or D1+2·D1+3 (data type D, L, or F). The minimum value of the sampling

D2 is turned on.
When the quantity of sampling cycles designated by device S3 is 0, sampling is started when the input to the AVRG instruction is turned on, andstopped when the sampling end input designated by device S2 is turned on. Then, the average, maximum, and minimum values are set to 3 devices
starting with device designated by D1.
When the sampling exceeds 65535 cycles, the average, maximum, and minimum values at this point are set to 3 devices starting with device
designated by D1, and sampling continues.
When the sampling end input is turned on before the sampling cycles designated by device S3 have been completed, sampling is stopped and theresults at this point are set to 3 devices starting with device designated by D1.
The average value is calculated to units, rounding the fractions of one decimal place.
When the sampling end input is not used, designate an internal relay or another valid device as a dummy for source device S2.
When F (float) data is selected and S1 does not comply with the normal floating-point format, a user program execution error will result, turning on
special internal relay M8004 and ERR LED on the SmartAXIS. When an error occurs, incorrect S1 data are skipped. Average, maximum, andminimum values are calculated from correct S1 data, and set to 3 devices starting with the device designated by D1. For details about user program

The PWM instructions output pulses at the specified frequency and duty cyclefrom the output port.
When the input is on, pulses are output according to the control register settings
specified by S1.
The pulse control information (output on/output complete/error) is stored in theinternal relays specified by D1 as the operation status.
When the initialization input specified by S2 is turned on, the initial values
configured in the WindLDR PWM instruction dialog box, on the Setting tab, arestored in the control registers.

Note: Configure multiple PULS (pulse output), PWM (pulse width modulation), RAMP (trapezoidal control), and ARAMP (RAMP with table)
instructions so that they do not share the same pulse output port.
However, the ZRN (zero return) instruction can be configured with the same pulse output port as the PULS (pulse output), PWM (pulse widthmodulation), RAMP (trapezoidal control), and ARAMP (RAMP with table) instructions.
Note: The PWM instruction cannot be used in an interrupt program.
If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS. For details about theuser program execution errors, see "User Program Execution Errors" on page 4-13.

This setting specifies the ON ratio (duty cycle) for the pulse frequency to output. The duty cycle can be set for output frequency
in increments of 1%. The pulse duty cycle can be set for output frequency in increments of 1% from 1 Hz to 50 Hz, but from 51
Hz to 1,000 Hz, the increments for the pulse duty cycle that can be specified to change according to the output frequency. The
increment becomes (pulse frequency ÷ 50)%. For example, when 51 Hz is specified for the pulse frequency, 51 ÷ 50 = 2(rounded up), so the increment is 2%. When 1,000 Hz is specified for the pulse frequency, 1000 ÷ 50 = 20, so the increment is20%. For increments of 2%, a value from 1 to 2 entered in Pulse width ratio is rounded up and handled as 2%, 3 to 4 isrounded up and handled as 4%. For increments of 20%, 1 to 20 is handled as 20%, 21 to 40 is handled as 40%.

When the RAMP instruction input is on, pulses are output according to the settings configured by the control registers. M50 turns
on during pulse output. M52 turns on or off while increasing or decreasing the pulse frequency. Pulses are output according to thefrequency change time, until they reach the steady pulse frequency (from the initial pulse frequency). The frequency increases ordecreases every 10 ms. Pulse output stops when the pulses configured by the preset value are output. At this time, M50 turns off
and M51 turns on.
If the RAMP instruction input turns off during pulse output, pulse output is canceled. If the RAMP instruction input turns on again,
the pulse count is reset and pulse counting starts. Even if the contents of the control registers are changed during pulse output,
the change is not reflected in the pulse output operation. The changed content is reflected the next time the RAMP instruction is
executed.
The changes from the initialization input are not reflected while the RAMP1 instruction input is on. If you wish to initialize the dataregisters with the initialization input, turn the initialization input on after turning off the input.

The ARAMP instructions output pulses with the frequency change
function according to the information in the frequency table.
When the input is on, pulses are output according to the frequency change
settings stored in the control register settings specified by S1. The pulse
frequency is controlled by combining multiple steps that define the change
time and steady pulse speed. The pulses change frequency at a constantrate until they reach the steady pulse frequency in the step option settings.
You can select to output pulses at the steady pulse frequency or to change
the frequency at a constant rate until the steady pulse frequency isreached, after pulses that maintain the frequency in the previous step are
output. The next step is executed when the number of pulses output
reaches the preset value. You can configure a maximum of 18 steps.

When the interrupt input configured by S3 is turned on, the step being executed is aborted and the interrupt step is executed.
The settings for the step being executed, including the preset value and the steady pulse frequency, are stored in the dataregisters specified by D1.
The control status, including the pulse output status (output on, output direction, output complete), is set as the operation status
in the internal relays specified by D2.
Note: Configure multiple PULS (pulse output), PWM (pulse width modulation), RAMP (ramp control), and ARAMP (RAMP with table) instructions sothat they do not share the same pulse output port.
However, the ZRN (zero return) instruction can be configured with the same pulse output port as the PULS (pulse output), PWM (pulse widthmodulation), RAMP (ramp control), and ARAMP (RAMP with table) instructions.
Note: The ARAMP instruction cannot be used in an interrupt program.

3. S2 (source 2): Initialization input

S2 specifies the initialization input.
When the initialization input S2 is turned on, the initial values configured in the WindLDR ARAMP instruction dialog box, on the
Setting tab, are stored in the control registers.
An external input (I0 to I35) (Note) or an internal relay (M0 to M1277) can be specified.
When the initialization input is on, the initial values are written to the data registers with each scan. To only initialize the values
one time, use the initialization input in combination with the SOTU (single output up) instruction or the SOTD (single output
down) instruction.
Note: For the 40-I/O type, external inputs (I0 to I27) can be used.

4. S3 (source 3): Interrupt input

When the interrupt input changes from off to on, the pulse output process for the running step is aborted, and pulse output
restarts with the settings for the step configured by the interrupt number.
In the following example, the interrupt input turns on while step 2 is running. Pulse output processing for step 2 aborts and theoperation transitions to step 12.

The information updated in the END processing is read as the interrupt input.
It is affected by the user program scan.

Notes:• Do not use the same input or internal relay as the interrupt input signal for the ARAMP1 and ARAMP2 instructions.
• To use the high-speed interrupt input signal, set the relevant input to Normal Input under Special Input on Function Area Settings. Do

not use the input as interrupt input, catch input, high-speed counter, or frequency measurement.
• When using the high-speed interrupt input, ensure that no chatter noise occurs in the interrupt input.
• When the interrupt input is turned on, the control direction (forward or reverse) is unchanged regardless of the control direction of theinterrupted step.

If the ARAMP instruction input turns off during pulse output, pulse output ends. If the ARAMP instruction input turns on again, theoperation starts from the beginning. Even if the contents of the data registers are changed during pulse output, the change is notreflected in the pulse output operation. The changed content is reflected the next time the ARAMP instruction is started.
The changes from the initialization input are not reflected while the ARAMP instruction input is on. If you wish to initialize the dataregisters with the initialization input, turn the initialization input on after turning off the ARAMP instruction input.

When the ARAMP instruction input changes from off to on, pulses are output from Q14 according to the settings configured by thedata registers. The reversible control signal is output from Q16 or Q12. When pulse output starts, M50 turns on. M52 turns on
while the pulse frequency is increasing or decreasing. The pulses increase and decrease according to the frequency change time
until they reach the steady pulse frequency from the current pulse frequency. When the configured number of pulses are output,
the pulses stop. In this situation, M50 turns off and M51 turns on.
If the ARAMP instruction input turns off during pulse output, pulse output ends. If this input turns on again, the operation starts
from the beginning. Even if the contents of the data registers are changed during pulse output, the change is not reflected in thepulse output operation. The changed content is reflected the next time the ARAMP instruction is started.
Forward and reverse cannot be changed until the pulse output pulse frequency is set to its minimum. In mode 1 for example,
forward and reverse cannot be changed until the pulse frequency is set to 200 Hz.
The changes from the initialization input are not reflected while the ARAMP1 instruction input is on. If you wish to initialize thedata registers with the initialization input, turn the initialization input on after turning off the input.

Dual timer instructions generate ON/OFF pulses of required durations from a designated output, internal relay, or shift register bit.
Four dual timers are available and the ON/OFF duration can be selected from 1 ms up to 65535 sec.
Teaching timer instruction measures the ON duration of the start input for the teaching timer instruction and stores the measured
data to a designated data register, which can be used as a preset value for a timer instruction.

Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Destination device D2 (system work area) uses 2 data registers starting with the device designated as D2. Data registers D0-D998 and D1000D1998 can be designated as D2. The two data registers are used for a system work area. Do not use these data registers for destinations of otheradvanced instructions, and do not change values of these data registers using the monitor function on WindLDR. If the data in these data registers
are changed, the dual timer does not operate correctly.
The dual timer instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal
relay M8004 and the ERR LED on the SmartAXIS.
When a user program execution error occurs, the execution of the instruction is canceled and the next instruction is executed. The data in D1(destination 1) is unchanged. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

Destination device D1 (measured value) uses 3 data registers starting with the device designated as D1. Data registers D0-D997 and D1000-D1997
can be designated as D1. Subsequent two data registers starting with destination device D1+1 are used for a system work area. Do not use thesetwo data registers for destinations of other advanced instructions, and do not change values of these data registers using the monitor function on
WindLDR. If the data in these data registers are changed, the teaching timer does not operate correctly.
The teaching timer instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal
relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page

Function

Description

FI pointer

The FI pointer indicates the position to store new data into the FIFO data file. When an
FIEX instruction is executed, the new data in data registers starting with the device
designated by S1 of the FIEX instruction is stored at the position indicated by the FI
pointer, and the FI pointer is incremented by 1 to indicate the position to store the next
data.
When the FI pointer indicates the last record of the FIFO data file, and an FIEX
instruction is executed, the FI pointer will return to 0.

FO pointer

The FO pointer indicates the position to retrieve the stored data from the FIFO data
file. When an FOEX instruction is executed, the data at the position indicated by the
FIFO pointer is retrieved and stored to the data registers starting with the device
designated by D1 of the FOEX instruction, and the FO pointer is incremented by 1 toindicate the position to retrieve the next data.
When the FO pointer indicates the last record of the FIFO data file, and an FOEX

Description

Data file full output

When the value stored in the FI pointer (D1+0) is equal to the value stored in the FOpointer (D1+1) – 1, the FIFO data file is full, and no more data can be stored. If an FIEX
instruction is executed when the FIFO data file is full, no operation is executed, and thedata file full output (D2+0) will be turned on.

D2+1

Data file empty output

When the value stored in the FI pointer (D1+0) is equal to the value stored in the FOpointer (D1+1), the FIFO data file is empty. If an FOEX instruction is executed when the
FIFO data file is empty, no operation is executed, and the data file empty output (D2+1)
will be turned on.

D2+2

For valid device address ranges, see "Device Addresses" on page 3-1.
Source S1 data specifies the value to be sought and the valid range depends on the data type.
The search range cannot straddle data registers and non-retentive data registers. Make sure that the sum of data register numbers designated by
S1 and S2 does not result in a different data register range.
For source S3 and destination D1, 1 word is always used without regard to the data type.
Destination D1 occupies two consecutive data registers starting with the device designated by D1. Data registers D0-D998 and D1000-D1998 can be
designated as destination D1.
When F (float) data is selected and S1 does not comply with the normal floating-point format, a user program execution error will result, turning on
special internal relay M8004 and ERR LED on the SmartAXIS. When a user program execution error occurs, the execution of the instruction iscanceled and the next instruction is executed.
When data in S2 to S2+(S3) does not comply with floating-point format, the data is skipped to continue the search and the results are stored in D1
and D1+1.
The NDSRC instruction cannot be used in an interrupt program.
If used, a user program execution error will result, turning on special internal relay M8004 and the ERR LED on the SmartAXIS.
When S3 is zero or the sum of S2 and S3 is not within the valid data register range, a user program execution error will result, turning on special
internal relay M8004 and ERR LED on the SmartAXIS. When a user program execution error occurs, the execution of the instruction is canceled andthe next instruction is executed.
For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.
Since the NDSRC instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

TADD (time addition) and TSUB (time subtraction) instructions add or subtract time data in two different modes. The data can beselected from time (hour, minute, and second) or date/time (year, month, day, day of week, hour, minute, and second).
HTOS (HMS to sec) and STOH (sec to HMS) instructions perform conversion of time data between hours, minutes, seconds andseconds.
HOUR (hour meter) instruction measures the on duration of the input and compares the total duration to a preset value. When thepreset value is reached, an output or internal relay is turned on.

25: USER COMMUNICATION INSTRUCTIONSIntroduction
User communication instructions convert data to the specified data type and transmit and receive that data.
The user communication instructions can be used on expansion communication ports or the Ethernet port. To perform user
communication with external devices connected on the expansion communication ports, use the TXD (user communicationtransmit) and RXD (user communication receive) instructions. To perform user communication with external devices connected
over the Ethernet, use the ETXD (User communication transmit over Ethernet) and ERXD (User communication receive over
Ethernet) instructions.

Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Transmit data designated by device S1 can be a maximum of 200 bytes.
When transmission is complete, an output or internal relay, designated by device D1, is turned on.
Destination 2 occupies two consecutive data registers starting with the device designated by D2. The transmit status data register, D0-D1998, storesthe status of transmission and error code. The next data register stores the byte count of transmitted data. The same data registers cannot be usedas transmit status registers for TXD2 through TXD3 instructions and receive status registers for RXD2 through RXD3 instructions.
The TXD instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay
M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

Precautions for Programming TXD Instruction• The SmartAXIS has five formatting areas each for executing TXD2 through TXD3 instructions, so five instructions each of TXD2 through TXD3 can beprocessed at the same time. If inputs to more than five of the same TXD instructions are turned on at the same time, an error code is set to the transmit
status data register, designated by device D2, in the excessive TXD instructions that cannot be executed.
• If the input for a TXD instruction turns on on while another TXD instruction is executed, the subsequent TXD instruction is executed 2 scan times after thepreceding TXD instruction is completed.
• Since TXD instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Designating Constant as S1When a constant value is designated as source device S1, one-byte data is transmitted without conversion. The valid transmit data
value depends on the data bits selected in the Communication Parameters dialog box. These data bits are set in Configuration >Comm. Ports, followed by selecting User Protocol in Port 2 through Port 3 list box and clicking the Configure button. When 7
data bits are selected as default, 00h through 7Fh is transmitted. When 8 data bits are selected, 00h through FFh is transmitted.
Constant values are entered in character or hexadecimal notation into the source data.
Constant (Character)
Any character available on the computer keyboard can be entered. One character is counted as one byte.

Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Receive format designated by device S1 can be a maximum of 200 bytes.
When data receive is complete, an output or internal relay, designated by device D1, is turned on.
Destination 2 occupies two consecutive data registers starting with the device designated by D2. The receive status data register, D0-D1998, storesthe status of data receive and error code. The next data register stores the byte count of received data. The same data registers can not be used astransmit status registers for TXD2 through TXD3 instructions and receive status registers for RXD2 through RXD3 instructions.
The RXD instructions cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal relay
M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors" on page 4-13.

Precautions for Programming the RXD Instruction• The SmartAXIS can execute a maximum of five instructions each of RXD2 through RXD3 that have a start delimiter at the same time. If a startdelimiter is not programmed in RXD2 through RXD3 instructions, the SmartAXIS can execute only one instruction each of RXD2 through RXD3 at
a time. If the start input for a RXD2 through RXD3 instruction is turned on while another RXD2 through RXD3 instruction, without a start delimiteris executed, a user communication error occurs.
• Since RXD instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.
• Once the input to the RXD instruction is turned on, the RXD is activated and ready for receiving incoming communication even after the input isturned off. When the RXD completes data receiving, the RXD is deactivated if the input to the RXD is off. Or, if the input is on, the RXD is madeready for receiving another communication. Special internal relays are available to deactivate all RXD instructions waiting for incoming
communication. For user communication receive instruction cancel flags, see "User Communication Receive Instruction Cancel Flag" on page 2520.

25: USER COMMUNICATION INSTRUCTIONSDesignating Data Register as S1When a data register is designated as source device S1, receive digits and conversion type must also be assigned. The received
data is divided into blocks of specified receive digits, converted in a specified conversion type, and stored to the designated dataregisters. Conversion types are available in ASCII to Binary, ASCII to BCD, and no conversion.
When repeat is designated, received data is divided, converted, and stored into as many data registers as the repeat cycles,
starting with the designated data register. There can be up to 99 repeat cycles.
When a data register is designated as source device S1, a delimiter can be included in the data register designation to end
receiving communication.

Delimiter
A delimiter for the data register in the receive format can be assigned. Using a delimiter, incoming data of variable length can bereceived and stored to data registers.
Delimiter

How the incoming data is stored to data registers

Designated

The incoming data is stored to data registers until all the data specified with receive digits, conversion type, and repeat
is processed or the specified delimiter is received.

No delimiter

The incoming data is stored to data registers until all the data specified with receive digits, conversion type, and repeat
is processed.

Note: Delimiters for data registers can be used in the receive format of RXD instructions only.

Designating Constant as Start Delimiter
A start delimiter can be programmed at the first byte in the receive format of a RXD instruction; the SmartAXIS will recognize thebeginning of valid communication, although a RXD instruction without a start delimiter can also be executed.
When a constant value is designated at the first byte of source device S1, the one-byte data serves as a start delimiter to start theprocessing of the received data.
A maximum of five instructions each of RXD2 through RXD3 with different start delimiters can be executed at the same time.
When the first byte of the incoming data matches the start delimiter of a RXD instruction, the received data is processed andstored according to the receive format specified in the RXD instruction. If the first byte of the incoming data does not match thestart delimiter of any RXD instruction that is executed, the SmartAXIS discards the incoming data and waits for the next
communication.

Multi-byte Start Delimiter
A start delimiter can be programmed at the first bytes in the receive format of a RXD instruction; the SmartAXIS will recognize thebeginning of valid communication, although a RXD instruction without a start delimiter can also be executed. A maximum of 5consecutive constants that are either character or hexadecimal from the first byte of the receive format are considered a multi-byte
start delimiter.
If a RXD instruction with a start delimiter is executed and another RXD instruction with the same start delimiter is executed, user
communication error code 5 is stored in the data register designated as the receive status of the second RXD instruction. When theerror occurs, the second RXD instruction is canceled, and the first RXD instruction executed is kept.
If a multi-byte start delimiter is assigned, and the incoming data does not match the entire multi-byte start delimiter, theSmartAXIS discards the incoming data and waits for the next communication.
When the first one byte is received, a timer is started to monitor the interval between incoming data even when a multi-byte startdelimiter is assigned. If data is not received in the period specified for the receive timeout value after receiving one byte of data, areceive timeout error occurs, and user communication error code 11 is stored in the status data register.

Start Delimiter

Example: Using Multi-byte Start Delimiter
The following example shows the advantages of using a multi-byte start delimiter rather than a single-byte start delimiter. A RXD
instruction processes incoming data from the master station. The incoming data is sent to multiple slave stations 0 through 9, andthe local slave station number is 1. Therefore, incoming data from the master station must be received only when the incoming
data is sent for the slave station 1.
• Incoming data

Incoming data consists of start delimiter STX, a slave station number which can be 0 through 9, data 0000 through 9999, and end
delimiter CR.

Slave Station Number: 0 through 9• Single-byte start delimiter

Only the first byte can be the start delimiter. The second byte of the incoming data, which is the slave station number, has to be
stored to data register D0, and extra ladder programming is needed to see whether the slave station number of the incoming
communication is 1 or not. Only when the slave station number is 1, received data stored in D1 is valid for the local PLC.

Delimiter

Designating Constant as End Delimiter
An end delimiter can be programmed at the end of the receive format of a RXD instruction; the SmartAXIS will recognize the endof valid communication, although RXD instructions without an end delimiter can also be executed.
When a constant value is designated at the end of source device S1, the one-byte data serves as an end delimiter to end theprocessing of the received data. End delimiters can be 00h through FFh. Constant values are entered in character or hexadecimal
notation into the source data. When using the same RXD instruction repeatedly in a user program, assign different end delimiters
for each RXD instruction.
If a character in incoming data matches the end delimiter, the RXD instruction ends receiving data at this point and starts
subsequent receive processing as specified. Even if a character matches the end delimiter at a position earlier than expected, theRXD instruction ends receiving data there.
If a BCC code is included in the receive format of a RXD instruction, an end delimiter can be positioned immediately before or after
the BCC code. If a data register or skip is designated between the BCC and end delimiter, correct receiving is not ensured.
When a RXD instruction without an end delimiter is executed, data receiving ends when the specified bytes of data in the receive
format, such as data registers and skips, have been received. In addition, data receiving also ends when the interval between
incoming data characters exceeds the receive timeout value specified in the Communication Parameters dialog box whether the
RXD has an end delimiter or not. The character interval timer is started when the first character of incoming communication isreceived and restarted each time the next character is received. When a character is not received within a predetermined period oftime, timeout occurs and the RXD ends data receive operation.

Constant for Verification
Constants excluding start and end delimiters can be configured in the receive format to verify the incoming data with theconstants, which are either characters or hexadecimal values. As many constants can be configured for the verification as required.
The verification result is stored in the receive status of the RXD instruction.
Example: Programming Constant for Verification
The following example shows the advantage of using constant for verification. The incoming data contains a constant value “1” inthe middle, and that constant value needs to be verified to see whether the incoming data is valid.
• Using Data Register

The incoming data including the constant value needs to be stored in data registers. When the RXD instruction completes receiving
the incoming data, the receive status contains 64, meaning the RXD instruction has completed without errors, even if the constantvalue is not an expected value. Extra ladder programming is needed to see whether the constant value in the incoming data iscorrect or not.

A constant to verify the constant value in the incoming data is designated in the receive format. If the constant value is not an

Note: When configuring constants, which are either characters or hexadecimal values, in the receive format, and the incoming data does not matchthe constants in the receive format, then a user communication error code is stored in the receive status. The error code contained in the receive
status depends on whether the constants are used as a start delimiter or as constants for verification. If used as a start delimiter, user
communication error code 7 is stored in the receive status, and the RXD instruction keeps waiting for valid incoming data. On the other hand, if used
as constants for verification, the receive status contains 74, and the RXD instruction finishes the execution. To repeat receiving incoming
communication, turn on the input for the RXD instruction.

25: USER COMMUNICATION INSTRUCTIONSBCC (Block Check Character)
The SmartAXIS has an automatic BCC calculation function to detect a communication error in incoming data. If a BCC code isdesignated in the receive format of a RXD instruction, the SmartAXIS calculates a BCC value for a specified starting position
through the position immediately preceding the BBC. It then compares the calculation result with the BCC code in the received
incoming data. The start position for the BCC calculation can be specified from the first byte through the 15th byte. The BCC canbe 1 or 2 digits.
When an end delimiter is not used in the RXD instruction, the BCC code must be positioned at the end of the receive format
designated in Source 1 device. When an end delimiter is used, the BCC code must be immediately before or after the end delimiter.
The SmartAXIS reads a specified number of BCC digits in the incoming data according to the receive format to calculate andcompare the received BCC code with the BCC calculation results.
BCC Calculation Start Position
The start position for the BCC calculation can be specified from the first byte through the 15th byte. The BCC is calculated for therange starting at the designated position up to the byte immediately before the BCC of the receive data.
Example: Received data consists of 17 bytes plus 2 BCC digits.

Comparing BCC Codes
The SmartAXIS compares the BCC calculation result with the BCC code in the received incoming data to check for any error in the incoming
communication due to external noises or other causes. If a disparity is found in the comparison, an error code is stored in the data register
designated as receive status in the RXD instruction. For user communication error code, see Chapter 10 "User Communication Instructions" - "User
Communication Error" in the SmartAXIS Pro/Lite User's Manual.

Example 1: BCC is calculated for the first byte through the sixth byte using the XOR format, converted in binary to ASCII, andcompared with the BCC code appended to the seventh and eighth bytes of the incoming data.

Designate an output, Q0 through Q21, or internal relay, M0 through M1277, as a device for the receive completion output.
When the start input for a RXD instruction is turned on, preparation for receiving data is initiated, followed by data conversion andstorage. When the data receive operation sequence is complete, the designated output or internal relay is turned on.
Conditions for Completion of Receiving Data
After starting to receive data, the RXD instruction can be completed in three ways depending on the designation of end delimiter and delimiter in thereceive format.
End Delimiter

When a specified byte count of data (digits × repeat) has been received.

Note: Whenever a receive timeout has occurred, data receiving stops arbitrarily.
Data receiving is complete when one of the above three conditions is met. To abort a RXD instruction, use the special internal relay for user
communication receive instruction cancel flag. See "User Communication Receive Instruction Cancel Flag" on page 25-20.

Example: A RXD instruction does not have an end delimiter and has a delimiter programmed in the receive format for dataregisters.

26: DATA LOG INSTRUCTIONSIntroduction
The data log instructions save log data for specified devices to the SD memory card.

DLOG (Data Log)DLOG

The DLOG instruction saves the values of the specified devices in the specified
data format as a CSV file on the SD memory card.

S1

D1

D2

*****

*****

*****

When the input is on, the date and time and the values of the specified devices
are output to the CSV file in the folder assigned by S1. When the execution of the
instruction finishes, the device assigned by D1 is turned on and the execution
status is stored to the device assigned by D2.
When the folder assigned by S1 does not exist on the SD memory card, thatfolder is created. The folder path is "DATA0001\DATALOG\User specified folder."For details on the folder structure, see Chapter 5 "Special Functions" - "SD
Memory Card" in the SmartAXIS Pro/Lite User's Manual.
The CSV file name is "DATE.csv." The date when the DLOG instruction is turned
on is used as DATE.
Example: If the date is September 30, 2011, the file name is "20110930.csv".

When a CSV file with the same date does not exist in the folder designated by S1, the CSV file is created and the header and thelog data is output.

When the execution of DLOG instruction finishes, the device designated by D1 is turned on and the status code is stored to thedevice designated by D2 according to the execution result. For status codes, see "3. D2 (destination 2): Execution status" on page26-3.
Notes:• The time required to create a new CSV file (create a file and output header) is 510 µs.
• When the SmartAXIS starts running and DLOG instruction is executed, the header is appended to the CSV file even if the same DLOG

instruction was executed previously within the same day.

26: DATA LOG INSTRUCTIONS
Notes:• The number of DLOG instructions that can be programmed in a user program is 48. However, make sure that the folder name specified by the

DLOG instruction is not duplicated by any folder names specified by the other DLOG instructions. When the folders are duplicated, log datawith a mixed format is output to the same CSV file.
• The DLOG instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal

relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors"on page 4-13.
• While the input to DLOG instruction is on, log data is repeatedly output to the CSV file. When you want to output the log data only one time,

add a SOTU (single output up instruction) or SOTD (single output down instruction) to the input condition. For SOTU or SOTD, see "SOTU
and SOTD (Single Output Up and Down)" on page 5-26.
• The process of writing data to the SD memory card for the DLOG instruction takes several scans. Once a DLOG instruction is executed, theprocess continues until the log data transfer is complete, regardless of any change in the instruction input. While the log data is being written
to the SD memory card, instructions are not being executed, even when the inputs to DLOG instructions are turned on. To execute the DLOG
instruction again, confirm that the previous data transfer process has finished, and then execute the instruction.

When the execution of the TRACE instruction finishes, the device designated by D1 is turned on and the status code is stored tothe device designated by D2 according to the execution result. For status codes, see "3. D2 (destination 2): Execution status" onpage 26-10.
Notes:• The TRACE instruction accumulates data while SmartAXIS is running but does not accumulate data when SmartAXIS is stopped.
• Data is accumulated while SmartAXIS is running even when the input to the TRACE instruction is off.
• When the input to the TRACE instruction is turned on, the accumulated data is output to the CSV file.
• The time required to create a new CSV file (create a file and output header) is 870 µs.
• Trace data is accumulated even when the MCS (master control set) instruction is on.

SMARTAXIS LADDER PROGRAMMING MANUAL FT9Y-B1382

26: DATA LOG INSTRUCTIONS
Notes:• The maximum number of TRACE instructions that can be programmed in a user program is three. Make sure that the folder name specified

by the TRACE instruction is not duplicated by any of the folder names specified by the other TRACE instructions. When the folders are
duplicated, trace data with a mixed format is output to the same CSV file.
• The number of scans of which the trace data can be saved to the CSV file when the TRACE instruction is executed one time depends on thenumber of devices specified to trace and the display type for each device. For details, see "9. Trace data size" on page 26-11.
• The TRACE instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on special internal

relay M8004 and the ERR LED on the SmartAXIS. For details about the user program execution errors, see "User Program Execution Errors"on page 4-13.
• Trace data is not accumulated when the TRACE instruction is skipped by the JMP (jump) instruction. For the JMP (jump) instruction, see "JMP

(Jump) and JEND (Jump End)" on page 5-29.
• While the input to the TRACE instruction is on, the trace data is repeatedly output to the CSV file. When you want to output the trace data

only one time, add a SOTU (single output up instruction) or SOTD (single output down instruction) to the input conditions. For SOTU (single
output up instruction) or SOTD (single output down instruction), see "Basic Instructions" - "SOTU and SOTD (Single Output Up and Down)"
on page 5-26.
• The data writing process to the SD memory card for the TRACE instruction takes several scans. Once a TRACE instruction is executed, theprocess continues until the trace data transfer is complete, regardless of any change in the instruction input. While the trace data is being
written to the SD memory card, the instruction is not executed even when the input to the TRACE instructions are turned on. To execute the
TRACE instruction again, confirm that the previous data writing process has finished, and then execute the instruction.

*****

*****

*****

*****

Operation
The PID instruction is used to perform temperature and other types of control.
When the input is on, auto tuning and PID control are performed.

Warning• Special technical knowledge about the PID control is required to use the PID function of the SmartAXIS Touch. Use of the

PID function without understanding the PID control may cause the SmartAXIS Touch to perform unexpected operation,
resulting in disorder of the control system, damage, or accidents.
• When using the PID instruction for feedback control, emergency stop and interlocking circuits must be configured outside

the SmartAXIS Touch. If such a circuit is configured inside the SmartAXIS Touch, failure of inputting the process variable
may cause equipment damage or accidents.
Note: The maximum number of PID instructions that can be programmed in a user program is six.
For details about each control, see "PID Control" on page 28-20.

12. Hysteresis
Set the range from the alarm action point to when the alarm output changes from ON to OFF.
When hysteresis is set to a large value, the alarm output will not change by slight variations. When hysteresis is set to asmall value, the alarm output will change by slight variations near the alarm action point, which may negatively impact
connected equipment.
The range is 0.1 to 6,553.5 (°C/°F) or 1 to 65,535 (voltage/current input).
However, when the alarm type is Upper/Lower Limit Alarm or Upper/Lower Limit Alarm with Standby, you must set
hysteresis so that 1 ≤ hysteresis < Alarm Value (11) is satisfied.
13. Delay Time
Set the time until the alarm output is turned ON after the condition to turn the alarm output ON is satisfied.
The delay time prevents the alarm output from turning ON unintentionally when there are fluctuations in the process
variable due to the effects of noise.
After the condition to turn the alarm output ON has been satisfied, if it is no longer satisfied by when the delay time elapses,
the alarm output does not turn ON.
The range is 0 to 10,000 s. When 0, the delay time is disabled.

it can be set in units of 1.

SMARTAXIS LADDER PROGRAMMING MANUAL FT9Y-B1382

28-9

28: PID INSTRUCTION
4. Proportional Band (S1+8)
The proportional action changes the output proportional to the deviation between the set point and process variable.
If the process variable is in the range of the proportional band, the control output (S3+6) turns on or in proportional to thedeviation. If the process variable is out of the proportional band, the control output (S3+6) is always on or off.
When the proportional band is made larger, the control output (S3+6) turns on and off from a state where the deviation is large,
so overshooting (process variable goes above the set point), undershooting (process variable falls below the set point), andhunting (process variable is in an unstable undulating state) decrease, but it takes time until the process variable reaches the set
point and the offset between the set point and the process variable becomes larger.
When the proportional band is made smaller, the control output starts turning on and off at near the set point, so the time until
the process variable reaches the set point decreases and the offset also becomes smaller, but hunting increases. If the
proportional band is set extremely small, the control is the same as on/off operation.
When auto tuning is used, the appropriate proportional band can be automatically set for the target application. For details, see“Auto Tuning (AT)” on page 28-21.
The proportional band can be set from ±0.01 to ±100.00% in 0.01% increments.
5. Integral Time (S1+9)With only the proportional action, an offset occurs between the set point and the process variable even when the target
application is in a stable state. In order to bring this offset close to 0, the integral action is required. Integral time is a factor that
determines the manipulated variable by the integral action. If the integral time is too short, the integral action becomes too large,
which causes hunting of a long cycle. Conversely, if the integral time is too long, the processing until the set point is reached willtake time. The integral execution range is - proportional band to + proportional band. If the process variable goes out of the
proportional band due to a change in the set point or a disturbance, the integration calculation stops. As a result, the response of
the output manipulated variable against the change in set point improves and undershoot and overshoot can be reduced.
When auto tuning is used, the appropriate integral time can be automatically set for the target application. For details, see “AutoTuning (AT)” on page 28-21.
The integral time can be set from 0.1 to 6553.5 seconds in 0.1 second increments.
6. Derivative Time (S1+10)
When the set point changes or when the difference between the set point and the process variable increases due to a
disturbance, the derivative action quickly brings the process variable close to the set point by increasing the manipulated
variable. When the derivative time is decreased, the derivative action becomes weaker and the response to rapid temperaturechanges becomes slower. The action to control rapid temperature increases also becomes weaker, so the time to reach the set
point will become shorter, but overshoot will occur more easily. When the derivative time is increased, the derivative action
becomes large and the response to rapid temperature changes becomes faster. The action to control rapid temperature
increases also becomes more powerful, so the time to reach the set point will become longer, but overshoot will occur less easily.
When auto tuning is used, the appropriate derivative time can be automatically set for the target application. For details, see“Auto Tuning (AT)” on page 28-21.
The derivative time can be set from 0.1 to 6553.5 seconds in 0.1 second increments.
7. Derivative Gain (S1+11)
When the derivative gain is set to a small value, the output manipulated variable is more easily affected by noise and changes inthe set point. When the derivative gain is set to a large value, the output manipulated variable is less easily affected by noiseand changes in the set point, but stability at normal times decreases. When noise or changes in the process variable occur,
normally set this to 20 to 30%.
The derivative gain can be set from 0 to 100% in 1% increments.
8. ARW (Anti Reset Windup) (S1+12)
Set the point to start the integral action. If the integral term is enabled from the start of execution of the PID instruction,
overshoot may be caused. Overshoot can be controlled by delaying the integral action with ARW linked to the proportional band.
ARW is normally 100%, which results in appropriate control with little overshoot. If ARW is set too small, overshoot can beeliminated, but an offset may occur.
The ARW can be set from 0 to 100%.
For example, when ARW=50% and proportional band=20.00%, the integral action starts from when the deviation becomes
smaller than 10%.
9. AT (Auto Tuning) Bias (S1+13)
Set the bias value for the auto tuning.
The auto tuning start point is determined by the AT bias value in 1 increments.
When process variable ≤ (set point - AT bias value):

AT start point = (set point - AT bias value)
When process variable ≥ (set point + AT bias value):

AT start point = (set point + AT bias value)
When (set point - AT bias value) < process variable < (set point + AT bias value):

AT start point = set point
For details, see “Auto Tuning (AT)” on page 28-21.
The AT bias can be set in the range of process variable minimum value < (set point - AT bias setting value) or process
variable maximum value > (set point + AT bias setting value) in units of 1.

Set the output for the PID control. The value can be specified as Analog Output or Data Register. The manipulated variablecalculated with the PID instruction according to the output manipulated variable limit (5) setting is stored.
When Analog Output is specified

An analog output (AQ0 to AQ5) can be set. The output is output from the set analog output (AQ0 to AQ5). For auto mode,the value that is output is the value stored in the output manipulated variable (analog value) (S1+19) having undergone
linear conversion in the range of the maximum value and the minimum value of the analog output (AQ0 to AQ5). For manualmode, the value that is output is the value stored in the manual mode output manipulated variable (S1+17) having
undergone linear conversion in the range of the maximum value and the minimum value of the analog output (AQ0 to AQ5).
The value of the output manipulated variable is automatically stored in the special data register that corresponds to theanalog output (AQ0 to AQ5) For the allocation of special data registers, see Chapter 27 "Internal Devices" - "2.2 Control
Device Addresses" in the SmartAXIS Touch User's Manual.
Note: To use an analog output (AQ0 to AQ5), the analog output must be configured in advance. For details on analog output settings, see Chapter
3 "Project" - "4.14 Analog Output" in the SmartAXIS Touch User's Manual

When Data Register is specified

The output manipulated variable for PID control is stored in control register S1+19 in the range of minimum value (4) ≤output manipulated variable ≤ maximum value (3). For manual mode, the stored value is that the one, stored in the manualmode output manipulated variable (S1+17), is converted linearly in the range of minimum value (4) and maximum value (3).
Configure parameters 2 through 4 when data register is selected as the output manipulated variable.

When Disabled

The manipulated variable calculated by the PID instruction is the output manipulated variable.
When Enable (upper and lower limits)

When the manipulated variable calculated by the PID instruction exceeds the output manipulated variable upper limit orlower limit, the upper limit value or the lower limit value is set as the output manipulated variable.
When Enable (percentage)

The result of the manipulated variable calculated by the PID instruction multiplied by 1 to 99% is set as the output
manipulated variable. The output manipulated variable lower limit (7) is disabled at this time.
6. Output manipulated variable upper limit/percentage (S1+14)
When Output manipulated variable restriction is Output manipulated variable (upper limit, lower limit)

Set the upper limit value of the output manipulated variable for the control output. When the manipulated variablecalculated by the PID instruction is higher than or equal to the output manipulated variable upper limit value, the set upper
limit value is set as the output manipulated variable for the control output. When setting the output manipulated variable
upper limit value, you must set the output manipulated variable upper limit value so that it satisfies output manipulated
variable lower limit value < output manipulated variable upper limit value.
The output manipulated variable upper limit value can be set from 0 to 100% in 1% increments.
When Enable (percentage)

The result of the manipulated variable calculated by the PID instruction multiplied by 1 to 99% is set as the output manipulated variable.
Output manipulated variable = manipulated variable calculated by the PID instruction x output manipulated variable (scaling factor)
7. Output manipulated variable lower limit (S1+15)
When Enable (upper and lower limits)

Set the lower limit value of the output manipulated variable for the control output. When the manipulated variable calculatedby the PID instruction is lower than or equal to the output manipulated variable lower limit value, the set lower limit value isset as the output manipulated variable for the control output. When setting the output manipulated variable lower limit
value, you must set the output manipulated variable lower limit value so that it satisfies output manipulated variable lower
limit value < output manipulated variable upper limit value. The output manipulated variable lower limit value can be set
from 0 to 100% in 1% increments.
When Enable (percentage)

The output manipulated variable lower limit is disabled.
8. Manual Mode Output MV (S1+17)
Set the output manipulated variable for manual mode. To enable this function, Auto/manual mode (S3+1) must be turned on.
The manual mode output manipulated variable is enabled for the output manipulated variable, the output manipulated variable(digital value), and the control output.
For switching between auto/manual mode, see “Auto/manual mode (S3+1)” on page 28-18.
The manual mode output manipulated variable can be set from 0.00 to 100.00% in 0.01% increments. When the output
manipulated variable limit is Output manipulated variable (upper limit, lower limit), the manual mode output manipulated
variable must be set between output manipulated variable lower limit value and output manipulated variable upper limit value.
9. Output MV Rate-of-Change (S1+16)
Set the output manipulated variable to change in a second. When the output manipulated variable rate of change is 0%/second,
this function is disabled.
When the difference between the set point and process variable is large, the normal output switches from off to on as shown inthe diagram on the next page, but by setting the output manipulated variable rate of change, the rate of change for the output
manipulated variable can be changed as shown in the diagram on the next page.

28: PID INSTRUCTIONPID Control
PID control performs adjustment operations to cancel the deviation between a single set point and the process variable that ispresent in normal temperature control. The types of PID control that can be used with the Touch are as follows.
■Proportional control
Proportional control outputs the manipulated variable in the proportional band that is proportional to the deviation between the set
point and the process variable. The output is turned on until the process variable reaches the A point (the proportional band), andwhen it exceeds this (it enters the proportional band), the control output starts to be turned on and off at the control cycle, andthen when the set point is exceeded, the control output is turned completely off. Along with the rise in temperature from the A
point to the set point, the control output on time becomes shorter and the off time becomes longer. An offset always occurs with
Proportional control. The P action is suitable for processes with no wasted time such as gas pressure control and level control.
When set to Proportional control, integral time and derivative time are automatically ignored.
Temperature

Proportional band

OffsetSet point

A point

Time• When the proportional band is made smaller, the control output turns on or off from near the set point, so the time until the process variablerises in temperature to the set point decreases and the offset also becomes smaller, but hunting increases.
• When the proportional band is made larger, the control output turns on or off from a temperature considerably lower than the target

temperature, so auto tuning and hunting eliminate, but it takes time until the process variable rises in temperature to the set point and theoffset between the set point and the process variable becomes larger.

■PI control
The I action automatically corrects the offset generated by Proportional control. However, for rapid changes in temperature due todisturbances, it will take time until the temperature stabilizes. The PI action is suitable for temperature control with a slow rate of change.
When set to PI control, derivative time is automatically 0.
Temperature

Proportional band

Set point
DisturbanceTime• If the integral time is too small, I (integral) control becomes more powerful and the offset can be corrected in a short amount of time, but thismay cause long cycles of hunting.

• If the integral time is too large, I (integral) control becomes weaker and it takes time to correct the offset.

■PD control
Compared to Proportional control, PD control increases the response to rapid temperature changes due to disturbances, stabilizes
control in a short amount of time, and attempts to improve the transient response characteristics. PD control is suitable totemperature control with a fast rate of change.
When set to PD control, integral time is automatically 0.
Temperature

Proportional band

Set point
DisturbanceTime• When the derivative time is decreased, the D (derivative) control becomes weaker and the response to rapid temperature changes becomesslower. The action to control rapid temperature increases also becomes weaker, so the rise in temperature time to the set point will become
faster, but overshooting the set point will occur more easily.
• When the derivative time is increased, the D (derivative) control becomes more powerful and the response to rapid temperature changes
becomes faster. The action to control rapid temperature increases also becomes more powerful, so the rise in temperature time to the set
point will become slower, but overshooting the set point will occur less easily.

28: PID INSTRUCTION■PID control
PID controls overshooting and hunting in Proportional control, corrects the offset in I (integral) control, and makes rapid
temperature changes due to disturbances converge on the set point in a short amount of time in D (derivative) control. Ideal
temperature control can be performed by using PID control. The parameters for the proportional band, integral time, andderivative time in PID control can be automatically set with auto tuning.

Auto Tuning (AT)
Optimal temperature control parameters will differ according to the characteristics of the subject to control. When performing PID
control, the proportional band (P), integral time (I), and derivative time (D) can be automatically set by executing auto tuning.
• Perform auto tuning during test operation.
• When auto tuning is executed near normal temperatures, temperature fluctuations cannot be imposed, so auto tuning may not end normally.

In such cases, set the values for P, I, and D manually.

• When auto turning is executed once, so long as the process is not changed, it is not necessary to execute auto tuning again.
• The PID parameters obtained with auto tuning may not be optimal values depending on the subject to control. In this case, manually adjust

the parameters.

■Auto tuning (AT)In order to automatically set the proportional band (P), integral time (I), and derivative time (D), fluctuations must be forcibly
imposed on the subject to control to set each value to the optimal value. In order to perform optimal auto tuning, fluctuations
must be imposed when the process variable has reached a value near the set point. Fluctuations can be imposed when the process
variable is near the set point by setting the AT bias. The relationship between the set point, AT bias, auto tuning start point, andfluctuation start point is as follows.
Process variable (PV) ≤ set point (SP) - AT bias setting value
When the AT bias setting is set to 20°C, fluctuations will start when the process variable (PV) reaches a temperature 20°C lower
than the set point (SP).

■To execute auto tuning (AT)To execute auto tuning, turn on the auto tuning execution flag (S3+6) when the PID instruction input is on. The values for P, I, andD will be automatically calculated. While auto tuning is executing, 1 is stored in the operation status (S1+2).
When auto tuning ends, the auto tuning execution flag (S3+6) turns off automatically, 2 is stored in the operation status (S1+2),
and the auto tuning completed output (S3+7) turns on.
■To cancel auto tuning (AT) execution
To cancel auto tuning while it is executing, turn off the auto tuning execution flag (S3+6). When the auto tuning execution flag
(S3+6) is turned off, auto tuning stops, 2 is stored in the operation status (S1+2), and the auto tuning completed output (S3+7)
turns on.
If auto tuning is canceled without completing, the values for P, I, and D are restored to the values before auto tuning was
executed.

Processing in One Scan
While the SmartAXIS is running, the SmartAXIS performs operations repeatedly such as input refreshing, ladder program
processing, and error checking.
A scan is the execution of all instructions from address zero to the END instruction. The time required for this execution is referred
to as one scan time. The scan time varies with respect to program length.
The current value of the scan time is stored to special data register D8023 (scan time current value), and the maximum value ofthe scan time is stored to special data register D8024 (scan time maximum value). These values can be viewed on the PLC status
screen of WindLDR while monitoring on a computer.

Executing Program Instructions
During the scan time, program instructions are processed sequentially starting with the first line of the ladder program, except forinterrupt program execution. One scan time of a ladder program is approximately equal to the total execution time of each
instruction shown on preceding pages.

Watchdog Timer
The watchdog timer monitors the time required for one program cycle (scan time) to prevent hardware malfunction. When theprocessing time for one scan exceeds the allowed time, a watchdog timer error occurs and the system is reset. If this is the case,place NOP instructions in the ladder diagram. The NOP instruction resets the watchdog timer. For details on the watchdog timer,
see Chapter 5 "Special Functions" – "Watchdog Timer Setting" in the SmartAXIS Pro/Lite User's Manual.
