Shielded wire
Connect only one side of the shielded wire to FG so that no current flows in the shield part.
If both sides of the shield are connected to FG, a closed circuit will be created between the shieldedwire and the ground, and a current will flow through the shielded wire, making it more susceptible tonoise. Be sure to ground FG.
Recommended cable: OTSC-VB 2PX0.5SQ by Onamba Co., Ltd. or equivalent (use twisted pairshielded wire).
Termination resistor (terminator)
The communication converter IF-400 (sold separately) has a built-in termination resistor.
The termination resistor is also called a terminator. It is a resistor attached to the end of wiring whenperipheral devices are connected to the host computer in a chain, and prevents signal reflection andsignal disturbance at the end.
Since this instrument has a built-in pull-up resistor and pull-down resistor, no termination resistor isrequired on the communication line.

9 Communication Procedure
Communication starts with command transmission from the host computer (hereafter Master), and ends
with the response of this instrument (hereafter Slave).

Slave

MasterCommand
Data
Command• Response with data
When the master sends the Read command, the slave responds withthe corresponding set value or current status.
• Acknowledgement
When the master sends the Write command, the slave responds bysending the acknowledgement after the processing is terminated.

Command• Negative acknowledgement
When the master sends a non-existent command or value out of the

Command
No response(Fig. 9-1)

setting range, the slave returns a negative acknowledgement.
• No response
The slave will not respond to the master in the following cases:• Broadcast address is set.
• Communication error (framing error, parity error)• CRC-16 discrepancy

Communication timing of the RS-485
Master Side (Take note while programming)
When the master starts transmission through the RS-485 communication line, the master is arranged
so as to provide an idle status (mark status) transmission period of 1 or more characters before
sending the command to ensure synchronization on the receiving side.
Set the program so that the master can disconnect the transmitter from the communication line withina 1 character transmission period after sending the command in preparation for reception of the
response from the slave.
To avoid collision of transmissions between the master and the slave, send the next command after
carefully checking that the master has received the response.
If a response to the command is not returned due to communication errors, set the Retry Processing
to send the command again. (It is recommended to execute Retry twice or more.)
Slave Side
When the slave starts transmission through the RS-485 communication line, the slave is arranged so
as to provide an idle status (mark status) transmission period of 1 ms or more (*) before sending the
response to ensure synchronization on the receiving side.
The slave is arranged so as to disconnect the transmitter from the communication line within a 1
character transmission period after sending the response.
(*): Can be set in “Communication response delay time setting (P.8-35)” within a range of 0 to 1000 ms.

10.2 Data Communication Interval
1.5 character transmission times or less(Communication speed 9600 bps, 19200 bps: 1.5 character transmission times,
Communication speed 38400 bps, 57600 bps: 750 µs)
To transmit continuously, an interval between characters which consist of one message, must be within
1.5 character transmission times.
If an interval lasts longer than 1.5 character transmission times, the PCA1 assumes that transmission
from the master is finished, which results in a communication error, and will not return a response.

10.3 Message Configuration
Message is configured to start after idle time is processed for more than 3.5 character transmissions,and end after idle time is processed for more than 3.5 character transmissions.
(Communication speed 9600 bps, 19200 bps: 3.5 character transmission times,
Communication speed 38400 bps, 57600 bps: 1.75 ms)
The data part has a maximum of 252 bytes.

CRC-16characters(1) Slave Address
Slave address is an individual instrument number on the slave side, and is set within the range 1 to 16(01H to 10H). The master identifies slaves by the slave address of the requested message.
The slave informs the master which slave is responding to the master by placing its own address in the
response message.
Slave address 0 (00H, Broadcast address) can identify all the slaves connected. However,slaves do not respond.
(2) Function CodeThe function code is the command code for the slave to undertake one of the following actions.
Type

Data
accessFunction CodeSub Function CodeContents

03(03H)

Reads a single or multiple piece(s) of data fromslave(s) (Amount of data: Max. 100).

06(06H)

Writes a single piece of data to slave(s).

16(10H)

Writes multiple pieces of data to slave(s) (Amountof data: Max. 20).
10-1

The function code is used to discern whether the response is normal (acknowledgement) or if any
error (negative acknowledgement) has occurred when the slave returns the response message to themaster.
When acknowledgement is returned, the slave simply returns the original function code.
When negative acknowledgement is returned, the MSB of the original function code is set as 1 for the
response.
For example, if the master sends request message setting 13H to the function code by mistake, slave
returns 93H by setting the MSB to 1, because the former is an illegal function.
For negative acknowledgement, the exception codes below are set to the data of the response
message, and returned to the master in order to inform it of what kind of error has occurred.
Exception CodeContents

1(01H)

Illegal function (Non-existent function)

2(02H)

Illegal data address (Non-existent data address)

3(03H)

17(11H)

Status unable to be written. (AT is performing.)(3) Data
Data differs depending on the function code.
A request message from the master is composed of a data item, amount of data and setting data.
A response message from the slave is composed of the byte count , data and exception codes innegative acknowledgements, corresponding to the request message.
The effective range of data is -32768 to 32767 (8000H to 7FFFH).
Refer to “11.1 Communication Command List (P.11-1 to P.11-20)”.
(4) Error Check
After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the data,
the calculated 16-bit data is appended to the end of message in sequence from low order to highorder.
[How to calculate CRC-16]
In the CRC-16 system, the information is divided by the polynomial series. The remainder is added
to the end of the information and transmitted. The generation of a polynomial series is as follows.
(Generation of polynomial series: X16 + X15 + X2 + 1)
1 Initialize the CRC-16 data (assumed as X) (FFFFH).
○
2 Calculate exclusive OR (XOR) with the 1st data and X. This is assumed as X.
○
3 Shift X one bit to the right. This is assumed as X.
○
4 When a carry is generated as a result of the shift, XOR is calculated by X of ○3 and the fixed○value (A001H). This is assumed as X. If a carry is not generated, go to step ○5 .
5 Repeat steps ○3 and ○
4 until shifting 8 times.
○
6 XOR is calculated with the next data and X. This is assumed as X.
○
7 Repeat steps ○3 to ○
5 .
○8 Repeat steps ○3 to ○
5 up to the final data.
○
9 Set X as CRC-16 to the end of message in sequence from low order to high order.

11.2 Data
11.2.1

Notes About Write/Read Command• The data (set value, decimal) is converted to a hexadecimal number.
Negative numbers are represented in 2's complement.
• Do not use undefined Data items. If they are used, negative acknowledgement will be returned ora random value will be written or read, resulting in malfunction.
• MODBUS protocol uses Holding Register addresses. The Holding Register addresses are createdas follows.
A data item is converted to decimal number, and the offset of 40001 is added. The result is theHolding Register address.
Using CH1 SV (0018H) as an example: Data item in the sending message is 0018H, however,
MODBUS protocol Holding Register address is 40025 (24+40001).

11.2.2

Write Command• The lifetime of the non-volatile IC memory is about 10 trillion writes.
Do not change the set value frequently by communication, as the set value storage retention time
may be shortened if the number of times is exceeded. (If the set value is the same as the value
before setting, it is not written to the non-volatile IC memory.)• When data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point
is used.
• If the operation is changed with Alarm 1 action to Alarm 4 action (0038H to 0047H), Alarm 1 value
to Alarm 4 value (0058H to 0077H) will return to the factory default values.
For the items to be initialized, refer to “11.5 Initialization Items by Changing Settings (P.11-23)”.
• Even if options are not ordered, writing via software communication will be possible. However,their command contents will not function.
• Communication parameters such as module address and communication speed of this instrument
cannot be written by software communication. Set it with the rotary switch for module address
selection and the dip switch for selecting communication specifications.
• When Write is executed using the Broadcast address [(00H) MODBUS protocol] command, thecommand is sent to all the connected slaves. However, a response is not returned.

11.2.3

Read Command• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal
point is used for a response.

11-21

11.3 Negative Acknowledgement
11.3.1

Error Code 2 (02H)

The slave will return Error code 2 (02H) in the following case.
• When non-existent data item is read or written.
11.3.2Error Code 3 (03H)

The slave will return Error code 3 (03H) in the following case.
• When a value out of the setting range is written.
11.3.3

Error Code 17 (11H)

The slave will return Error code 17 (11H) in the following case.
• When AT execution (0001H) is written with AT execution/stop selection (0008H to 000BH) during
PI operation or ON/OFF operation.
• When AT execution (0001H) is written with AT execution/stop selection (0008H to 000BH) during
AT execution.
When the control enable/disable selection (0004H to 0007H) is written during AT execution.
• When manual control MV setting (0014H to 0017H) is written during automatic control.

11.4 Notes on Programming Monitoring Software
11.4.1

How to Speed up the Scan Time

When monitoring multiple this instrument, set the program so that the requisite minimum pieces ofdata such as PV (03E8H to 03EBH), MV (03ECH to 03EFH), Status flag 1 (03F4H to 03F7H) can beread.
For other data, set the program so that they can be read only when their set value has changed.
This will speed up the scan time.
11.4.2

How to Read PID Parameters after AT or Start-up AT Finishes

While AT or Start-up AT is performing, this instrument sets “B1: AT Perform/Cancel” of “Status flag 1(03F4H to 03F7H)” to “1: AT Perform”.
After AT or Start-up AT is finished, PID parameters are updated.
On the monitoring software side, check that “B1: AT Perform/Cancel” of “Status flag 1 (03F4H to
03F7H)” has been set to “0: AT Cancel”, then read parameters such as P, I, D.
11.4.3

Notes on Batch Transmission of All Setting Values• If the operation is changed with Alarm 1 action to Alarm 4 action (0038H to 0047H), Alarm 1 value
to Alarm 4 value (0058H to 0077H) will return to the factory default values.
Send the Alarm action and then the Alarm value.
For the items to be initialized, refer to “11.5 Items to be Initialized by Changing Settings (P.11-23)”.
• If the input type is changed with Input type (00C8H to 00CBH), the setting values such as SV,
Proportional band, and Alarm 1 value are initialized.
Send the Input type and then the other setting values.
For the items to be initialized, refer to “11.5 Initialization Items by Changing Settings (P.11-23)”.

12.2.1

In order to set each value of P, I, D and ARW automatically, the AT process should be made tofluctuate to obtain an optimal value.
For DC voltage, direct current inputs, the AT process will fluctuate around the SV for conditions of [A],[B] and [C] below. One of 3 types of fluctuation below is automatically selected depending on thedeviation between SV and PV.
When AT is executed under Gap-PID control, D is calculated in 0 seconds.
[A] If there is a large difference between the SV and PV as the temperature is rising
When AT bias is set to 20°C (°F), AT process will fluctuate at the temperature 20°C (°F) lower thanthe SV.

Start-up AT

Start-up AT calculates each set value of P, I, D only in the temperature rising state when normal AT is
not performed due to temperature interference.
The Start-up AT is not executed for "Heating/Cooling Control" or "Direct action". Select "Normal AT" in"AT Action" and execute.
The start-up AT execution selection value is stored inside this instrument. Therefore, if "Control
enable/disable" is selected for "Control enable", Start-up AT is executed every time.
If you want to stop the Start-up AT, select "Normal AT" in "AT Action".

12.3 Set Alarm
For Alarm output, the alarm value is set by deviation from the SV (excluding Process alarm), and if the
PV goes outside the range, the Alarm output is turned ON (turned OFF for High/Low limit range alarm).
It can select from High limit alarm, Low limit alarm, High/Low limits alarm, High/Low limit range alarm,
Process high alarm, Process low alarm, High limit with standby alarm, Low limit with standby alarm,
High/Low limits with standby alarm, High/Low limits alarm individually, High/Low limit range alarm
individually, High/Low limits with standby alarm individually or no operation.
Refer to “14.5.3 Alarm Action (P.14-33, P.14-34)” for detail of alarm action.
Alarm settings are made using Alarm action and Alarm value.
If the operation is changed with Alarm 1 action to Alarm 4 action (0038H to 0047H), Alarm 1 value to
Alarm 4 value (0058H to 0077H) will return to the factory default values.

12.4 Correct Process Variable
When a sensor cannot be set at the exact location where control is desired, the sensor-measured
temperature may deviate from the temperature in the controlled location. When using multiple indicating
controllers, sometimes the measured temperatures do not concur due to differences in sensor accuracy
or dispersion of load capacities. In such a case, the control can be set at the desired temperature byadjusting the input value of sensors. However, it is effective within the input rated range regardless of thesensor correction value.
The input value is corrected by the sensor correction factor and the sensor correction.
The sensor correction factor sets the slope, and the sensor correction sets the difference between
before and after correction.
PV after input correction is expressed by the following formula.
PV after input correction =Current PV × Sensor correction factor setting value + (Sensor correction setting value)
An example of input value correction using a combination of Sensor correction factor and Sensor
correction is shown below.

12.5 Auto/Manual Control Switch
Switching between Automatic control and Manual control is done by Auto/Manual control.
If control action is switched from automatic to manual and vice versa, balanceless-bumpless function
works to prevent a sudden change in MV.
With Manual control, MV can be set arbitrarily. (*)
Set MV with Manual MV.
Manual control MV setting range: -5.0 to 105.0 %Auto/Manual control is Automatic control when the instrument power is turned ON.
(*): If the sensor fails in manual control, the MV will be 0%.

13 Communication with PLC Using SIF Function
The SIF function (Smart InterFace, programless communication function) is a function that serially connects
the PLC Q series (manufactured by Mitsubishi Electric Corp.) and this instrument, and reads and writes
various data to and from PLC registers using the communication protocol of the PLC.
The following communication protocols and commands are supported.
Communication protocol

Format 4

Communication command

A compatible 1C frame AnA/AnU common command (QR/QW)

Using the console software (SWC-QTC101M), select the PLC register start number, PLC register address,
the monitoring items and setting items to be linked, and set the specifications.
The control module QTC1-4P (with power supply / communication option) becomes the master, and theselected monitor item is periodically written to the PLC register by using the QW command, and the value ofthe PLC register is constantly updated.
In addition, the selected setting items are read from the PLC register in response to a setting request using
the QR command.
When the read data is changed, the set value of control module QTC1-4P (with power supply /communication option), control module QTC1-40 (no power supply / communication option) or control
module QTC1-20 (no power supply / communication option) is updated.

13.7.1

Communication Procedure(1) The control module QTC1-4P becomes the master and collects the valid monitor items andsetting items of the control module QTC1-40 (slave).
(2) After the PLC communication start waiting time has elapsed, the control module QTC1-4P
periodically writes the item selected in the monitor items to the PLC register.
Also, the item selected from the setting items is read from the PLC register in response to asetting request.

1 to 112: Transfers only the data (1 data) of the item selected in setting item 1 to 7 selection.
(2) Setting request command
The setting request command includes setting request and monitor request.
B0: Setting request (PLC → QTC1-4P)
The control module QTC1-4P is a command to request to read the data of the setting item of
the PLC register.
B1: Monitor request (QTC1-4P → PLC)
The control module QTC1-4P is a command to request to write the data of the setting item of
the PLC register.
If setting request and monitor request are set at the same time, processing is performed in theorder of setting request (QTC1-4P reads the data of the setting item in the PLC register) and thenmonitor request (writing the data of the setting item in the PLC register).
If a setting request is set during monitor request, the monitor request is discarded and the monitor
request is made again after the setting request.

14.1 Control Action Explanation
With the control action selection, any control type can be selected from 2 DOF PID control, Fast-PID
control, Slow-PID control, ON-OFF control, or Gap-PID control.
The control action selection can be selected only when control prohibited.
When the integration time is set to 0 or 0.0, Slow-PID control cannot be selected.
Optimum control is possible by selecting the control type according to the intended use and process.
The factory default settings of the control parameters when switching the control type are shown below.

2 DOF PID Control

The 2 DOF PID control is control type that achieves both “following characteristics when SV ischanged” and “disturbance suppression”.
The 2 DOF means that the above two characteristics can be adjusted independently.
“Following characteristics when SV is changed” is adjusted by proportional gain 2 degrees of freedom
coefficient (α) and integral 2 degrees of freedom coefficient (β), and “disturbance suppression” isadjusted by proportional band, integral time and derivative time.
The table below shows the relationship between response speed, overshoot/undershoot, and steady statearrival time depending on the settings of Proportional gain 2 DOF coefficient (α) and Integral 2 DOF
coefficient (β).

Fast-PID Control

The Fast-PID control is a general control type for fixed value control.

14.1.3Slow-PID Control

The Slow-PID control is a control type that is effective for processes that do not want to generate
overshoot or for processes in which PV does not easily drop once PV exceeds SV.

14.1.4ON-OFF Control

The control output is turned on when PV is

Overshoot, undershoot, and hunting will occur.
The ON-OFF control is suitable for processes

OFF(Fig. 14.1.4-1)
Overshoot / UndershootAs shown in (Fig. 14.1.4-1), if the temperature of the controlled object rises, it may exceed SV
significantly. This is called overshoot.
Also, lowering the temperature from the SV is called undershoot.
Hunting
As shown in (Fig. 14.1.4-1), it means the state when the control result becomes oscillatory.

14.1.5

Gap-PID Control

If the PV is noisy or the operating part has hysteresis, aslight fluctuation may continue near the deviation of zero.

SV

In such a case, the dead zone is usually used, but since

Fast responsecontrol is not performed within the dead zone, PV changes

It is suitable for fast response processes such as flow rate and valves.

14.1.6

PID Control Parameters

P control, PI control, PD control or deviation PID control can be performed by setting the PID control
parameter.
(1) P control
When the integral time and derivative
time are set to 0, P control is performed.
P control is a control operation that
outputs a manipulated variable
proportional to the deviation between SV
and PV within the proportional band.
Control output is ON until PV reaches
point A. When it exceeds this (when it
enters the proportional band), the control
output starts to turn ON/OFF in the
proportional cycle, and when it exceeds
SV, the control output turns OFF.

PV

Proportional band

OffsetSV

Point A

(Fig. 14.1.6-1)

Time

As the temperature rises from point A to SV, the control output ON time becomes shorter and the
OFF time becomes longer. Compared to ON-OFF control, overshoot is eliminated and hunting is
reduced, but offset occurs.
P control is suitable for processes with no dead time such as gas pressure control and level
control.
••

When the proportional band is reduced, the control output turns ON/OFF from around SV, so
the time until the PV temperature rises to SV becomes shorter and the offset becomes smaller,
but hunting becomes larger.
If the proportional band is made extremely small, the control will be similar to the ON-OFF
control.
When the proportional band is increased, the control output turns ON/OFF from a temperature
considerably lower than SV, so overshoot and hunting are reduced, but it takes time for PV torise to SV, and also for SV and PV. The offset will also increase.

(2) PI control
When the derivative time is set to 0, PI
control is performed.
In PI control, the offset generated by P
control is automatically corrected by the
integral action, and temperature control
is performed with SV. However, it takes
time for the temperature to stabilizeeven if the temperature changes rapidly
due to disturbance.
PI control is suitable for temperature
control, which changes slowly.
••PV

Proportional band

SV
DisturbanceTime(Fig. 14.1.6-2)

If the integral time is too short, the integral action will be strong and the offset can be corrected
in a short time, but this may cause hunting with a long cycle.
If the integral time is too long, the integral action will be weak and it will take time to correct theoffset.

14-4

(3) PD control
When the integral time is set to 0, PD

PV

control is performed.

Proportional band

SV

Compared to P control, PD control has
a quicker response to rapid temperature

Disturbancechanges due to disturbances, stabilizes
control in a short time, and improvestransient response characteristics.
Time

PD control is suitable for temperature
control with fast changing speed.
•(Fig. 14.1.6-3)

Decreasing the derivative time weakens the derivative action and delays the response to rapid
temperature changes. Also, since the function of suppressing a rapid temperature rise is
weakened, the temperature rise time up to SV is shortened, but overshooting tends to occur
correspondingly.

•

Increasing the derivative time strengthens the derivative action, resulting in faster response to
rapid temperature changes. Also, since the function of suppressing a sudden temperature rise
becomes stronger, the temperature rise time to SV becomes slower, but overshooting is lesslikely to occur.

(4) Deviation PID control

CautionThe proportional gain 2 DOF coefficient (α) and the derivative 2 DOF coefficient (γ, Cd) must be
set only when using deviation PID control.
For other controls, do not change The proportional gain 2 DOF coefficient (α) and the derivative 2
DOF coefficient (γ, Cd).
When the Fast-PID control is selected inPVthe control action selection and theSVproportional gain 2 DOF coefficient (α) is
Disturb

set to 1.00 and the derivative 2 DOF
coefficient (γ) is set to 1.00, the deviation
PID control is performed.
The feature of deviation PID control isTimethat only the response after SV change is
fast.

(Fig. 14.1.6-4)

It is suitable for program control and cascade control using the SV rise rate and SV fall rate.
It is not suitable for processes that cannot accept sudden changes in MV.

14.2.2Integral/Derivative Decimal Point Position

Select whether the integral time or the derivative time has no decimal point or has a decimal point.
When there is no decimal point and there is a decimal point, it is automatically converted to a value
0.1 times the current set value.
Also, when the decimal point is changed to the one without a decimal point, the value is automaticallyconverted to 10 times the current set value.
If the setting goes out of the setting range by changing the position of the decimal point, it becomes
the setting range upper limit value or lower limit value.

When the PV does not rise above the loop break alarm action width setting within the loop breakalarm time, even if MV reaches 100% or the output high limit, the loop break alarm is activated.
When the PV does not fall above the loop break alarm action width setting within the loop breakalarm time, even if MV reaches 0% or the output low limit, the loop break alarm is activated.
When control action is Direction action
When the PV does not fall above the loop break alarm action width setting within the loop breakalarm time, even if MV reaches 100% or the output high limit, the loop break alarm is activated.
When the PV does not rise above the loop break alarm action width setting within the loop breakalarm time, even if MV reaches 0% or the output low limit, the loop break alarm is activated.
14.2.7

Set Value Ramp Functio

When the SV is changed, from before to after the change SV is controlled at the setting change rate.
When the power is turned on, the rate of change from PV to SV at that time is controlled.
If set to 0, this function will not work.

Non-volatile IC Memory Data Save

Select whether to allow or prohibit saving data to the non-volatile IC memory.
If you select save prohibition, can temporarily change all the set values, but if turn the power off andthen on, it will return to the value before selecting save prohibition.
14.2.10 Auto/Manual Control Switching
Switches between automatic control and manual control.
When switching from automatic control to manual control or from manual control to automatic control,
the balanceless bumpless function prevents sudden changes in MV.
MV can be set arbitrarily by switching to manual control. (*)
Manual control MV setting range: -5.0 to 105.0 %When the instrument power is turned on, it will be automatically controlled.
(*): If the sensor fails in manual control, the MV will be 0%.
14.2.11 Sensor Correction Factor

14.2.12 Sensor Correction
If the temperature at the control location and the temperature at the sensor location are different, PV
is corrected.
However, it is valid within the input rated range regardless of the sensor correction value.
PV after input correction is expressed by the following formula.
PV after input correction =Current PV ×Sensor correction factor setting value + (Sensor correction setting value)14-9

14.2.13 Output Rate-of-Change Limit

14.2.14 Control Function
Select Standard, Heating/Cooling control, Cascade control or Output selection function, for control
function selection.
The control function selection can be selected only when control prohibited.
(1) Heating/Cooling control
The heating/cooling control is a control that is combined with cooling operation when it is difficult tocontrol the temperature control of the controlled object only by heating operation.
The control result calculated according to SV and PV is divided into heating output and cooling
output and output.
When PV is larger than SV, cooling output is output.
When PV is smaller than SV, heating output is output.
It is possible to set the band that outputs both heating output and cooling output (overlap), and theband that does not output both (dead band).
Also, the cooling action mode can be selected from Air cooling (Linear characteristics), Oil cooling(1.5th power of the linear characteristic s) or Water cooling (2nd power of the linear characteristic).
The output characteristics are as shown below for cooling MV.

operations for the controlled object is effective.

(2) Cascade control
The cascade control is a method of combining two PID controls to form one feedback loop andcontrolling.
This is effective when controlling a control target that has an extremely long delay time or deadtime from the change of MV to the measurement of the control target.
Although it takes longer for PV to reach SV, highly stable control is possible.
When the cascade control is selected for CH1 in the control function selection, the cascade control
is performed with CH1 as the master and CH2 as the slave.
When the cascade control is selected for CH3 in the control function selection, the cascade control
is performed with CH3 as the master and CH4 as the slave.

The MV on the master side obtained from the SV on the master side (CH1 or CH3) and PV issubstituted for the SV on the slave side (CH2 or CH4), and the slave side performs control
calculation and controls on the MV on the slave side.
The control output on the master side is OFF (0 mA for current output).
MV (0 to 100%) on the master side is converted according to the setting of slave scale low limit
value to slave scale high limit value, and becomes SV on the slave side.
For example, if the slave scale low limit value is 100°C and the slave scale high limit value is
400°C, the master side MV is 0% 100°C, 50% 200°C, 100% 400°C is the SV on the slave side.
It is necessary to design the system so that the control on the slave side has less delay than thecontrol on the master side and a quick control response can be obtained.
(Example)
This is an application that selects the cascade control for CH1 in control function selection,
uses CH1 as the master and CH2 as the slave, and adjusts the heat quantity of the heaterusing the power controller to adjust the temperature of the controlled object.

This function suppresses the peak power value when there is a power limit for the facility.
By setting the total current, power suppression is controlled when the sum of the current values
set for each channel is less than or equal to the total current value. However, this function does
not work for DC current output and DC voltage output.

When the communication expansion module QMC1 is not used, the control module QTC1-4P(with power supply / communication option) becomes the master, and the master channel andslave channel are selected from the master input channel by auto balance control master/slave
selection.
The auto balance control function does not work when the master channel is not selected.
When Enabled is selected for Auto balance control Enabled/Disabled selection, control
prohibited is changed to control allowed to start auto balance control.
The slave channels that are allowed to control within 10 seconds from the master channel on
which autobalance control was started are the target channels for autobalance control.
Slave channels that have been allowed to control after 10 seconds have passed (during
automatic balance control operation) are excluded from normal operation and are controlled
14-17

normally.
When the auto balance control function operates, the SV of the slave channel heats up
according to the PV of the master channel.
If the master channel has an input error, cancel the auto balance control function.
Slave channels that have no input error are individually controlled normally.
The set value ramp function is disabled during auto balance control.
It is also invalid when 2 DOF PID control, Fast-PID control, ON-OFF control or Gap-PID control
is selected in control action selection.
When using the auto balance control function, the same input range is used for the inputs thatare used for auto balance control.
For direct current input and DC voltage input, set the scaling high limit and scaling low limit to
the same setting.

Auto balance control interlock/alone selection
Select whether the auto balance control function is interlock or alone.
Both interlock and alone can be selected within one unit. However, connect the modules forwhich Interlock is selected continuously for the number of communication management
modules.
If the module for which Alone is selected is connected to the modules that are connected insuccession, the subsequent modules will not be linked.
• Interlock
Performs the auto balance control between modules.
Auto balance control can be performed as one group within one unit consisting ofcommunication expansion module QMC1 or control module QTC1-4P and control module
QTC1-40.
• AlonePerforms auto balance control within the module.
You can use the channels in the control module for auto balance control.

Auto balance control start output setting
When using the auto balance control function, the target value of the master channel is SV, but
the SV of the slave channel becomes the PV of the master channel, so the slave channel does
not start the auto balance control unless the master channel heats up. ..
As a result, the temperature of the slave channel is delayed and a temperature difference withthe master channel is generated, so that the MV is set so that the output of the slave channel
turns on when auto balance control starts in order to prevent deterioration of simultaneity.
The setting value of 0.00 to 1.00 corresponds to 0 to 100%.
Auto balance control start condition setting
The auto balance control is started in the following cases.
• When input is not burnout or underscale• When AT Cancel is selected in AT Perform/Cancel• When master is selected in master/slave selection• When Reverse action is selected in Direct/Reverse action selection• When the heater burnout alarm or loop break alarm is not generated
Auto balance control cancel condition setting
The auto balance control is canceled in the following cases.
• When input is not burnout or underscale• When AT Perform is selected in AT Perform/Cancel• When Direct action is selected in Direct/Reverse action selection• When a Heater burnout alarm or Loop break alarm occurs on the master channel. However,
if a Heater burnout alarm or Loop break alarm occurs on a slave channel, the auto balance
control is canceled only for that channel.
• When Control Prohibited is selected in Control Enable/Prohibited selection
Auto balance control cancel area setting
When the PV of the master channel reaches the autobalance control cancel area and when the
PV of each slave channel reaches the autobalance control cancel area, the auto balance
control function is released.
Master channel PV ≧ Master channel SV - Auto balance control cancel area
(When 0 is set, the auto balance control cancel area is twice the proportional band of themaster channel.)
Slave channel PV ≧ Slave channel SV - Auto balance control cancel area
(When 0 is set, the auto balance control cancel area is twice the proportional band of themaster channel.)Number of communication management module setting
Set the number of units including the master module.
If two slave modules for interlock are connected, set them as three.

Output Gain – Bias Function

When controlling the temperature of the metal plate, the heater is controlled at multiple points.
However, if multiple outputs are used for the inputs and the distribution of the output amount is
known in advance, the ratio and bias for MV (reference output) can be set to perform uniform
control.

Input Math Function

In Input math function selection, select Standard, Difference input or Addition input.
The input math function selected for CH1 corresponds to CH1 and CH2, and the input math function
selected for CH3 corresponds to CH3 and CH4. However, if heating/cooling control, cascade control
or output selection function is selected for control function selection, the input math function is invalid.
Standard

The input value of CH is used as PV for control.

Difference

The temperature difference between CH1 and CH2 is used as the PV for

input

CH1 and is controlled by CH1.
CH1 PV = CH1 PV - CH2 PV
The temperature difference between CH3 and CH4 is used as the PV for
CH3 and is controlled by CH3.
CH3 PV = CH3 PV - CH4 PV
Each setting value such as scaling and PV filter time constant can be set
for each channel.
When performing AT with the differece input specifications, execute AT
individually for each channel and then select differece input.

Addition

The added value of CH1 and CH2 is used as the PV for CH1 and is

input

controlled by CH1.
CH1 PV = CH1 PV + CH2 PV
The added value of CH3 and CH4 is used as the PV for CH3 and iscontrolled by CH3.
CH3 PV = CH3 PV + CH4 PV
Each setting value such as scaling and PV filter time constant can be set
for each channel.
When performing AT with the addition input specifications, execute AT
individually for each channel and then select addition input.

Input Difference Selection

Input difference selection detects the input difference between the current channel and the selectedchannel, and when the input difference detection setting exceeds the set value, the input difference
flag of status flag 1 B12: Set “out of range”. However, this function does not work when the own
channel is selected in input difference selection.

Automatic Cold Junction Temperature Compensation

Detect the temperature of the connection terminal between the thermocouple and the instrument, andmake it the same as if the reference contact is always set to 0°C (32°F). (Only valid for channels forwhich thermocouple input is selected.)

14.4.4PV Filter Time ConstantThis is a function to stabilize the PV of the process (pressure, flow rate, etc.) where the PV fluctuation
before the PV filter processing is performed by performing the temporary delay calculation of the PV
before the PV filter processing with the filter function on the software.
When PV before PV filter processing changes stepwise as shown in (Fig. 14.4.4-1), if PV time
constant (T) is set, PV filter will be set after T seconds as shown in (Fig. 14.4.4-2). It changes to reach
63% of the PV after treatment.
If the set value is too large, the control result may be adversely affected by the delay in response.

Gap-PID control

If the PV is noisy or if the operating part has hysteresis, a slight fluctuation may
continue near the deviation of zero.
In such a case, the dead zone is normally used, but since control is not
performed within the dead zone, PV changes during disturbance.
Therefore, it is a control method that gives deviation characteristics within thedead zone and responds to disturbance.

Auto balance control

This function suppresses partial burning and mechanical strain by performing

functionsoaking on one control target at multiple control points.
When using the communication expansion module QMC1, QMC1 becomes themaster and transfers data between control modules.
When the communication expansion module QMC1 is not used, the control
module QTC1-4P (with power supply / communication option) becomes themaster, and the master channel and slave channel are selected from themaster input channel by auto balance control master/slave selection.
The auto balance control function does not work when the master channel is
not selected.
When Enabled is selected for Auto balance control Enabled/Disabled
selection, control prohibited is changed to control allowed to start auto balance
control.
The slave channels that are allowed to control within 10 seconds from themaster channel on which autobalance control was started are the target
channels for autobalance control.
Slave channels that have been allowed to control after 10 seconds havepassed (during automatic balance control operation) are excluded from normal
operation and are controlled normally.
When the auto balance control function operates, the SV of the slave channel
heats up according to the PV of the master channel.
If the master channel has an input error, cancel the auto balance control
function.
Slave channels that have no input error are individually controlled normally.
The set value ramp function is disabled during auto balance control.
It is also invalid when 2 DOF PID control, Fast-PID control, ON-OFF control or
Gap-PID control is selected in control action selection.
When using the auto balance control function, the same input range is used forthe inputs that are used for auto balance control.
For direct current input and DC voltage input, set the scaling high limit andscaling low limit to the same setting.

Auto balance

When using the auto balance control function, the target value of the master

control startchannel is SV, but since the SV of the slave channel becomes the PV of theoutput setting

master channel, the slave channel does not start the auto balance control
unless the master channel heats up.
As a result, the temperature rise of the slave channel is delayed, a temperature
difference with the master channel is generated, and in order to prevent thesimultaneity from being deteriorated, the MV is set so that the output of theslave channel turns on at the start of the auto balance control.

control cancel• When input is not burnout or underscalecondition setting• When AT Perform is selected in AT Perform/Cancel• When Direct action is selected in Direct/Reverse action selection• When a Heater burnout alarm or Loop break alarm occurs on the masterchannel. However, if a Heater burnout alarm or Loop break alarm occurs ona slave channel, the auto balance control is canceled only for that channel.

How to check whether the sensor isburnt out
• For thermocouple
If the input terminals of this
instrument are short-circuited andthe around room temperature isindicated, this instrument is normal
and the sensor may be burn out.
• For RTD
If a resistance of approx. 100 Ω isconnected to the input terminal(between A and B) of this instrument
and the input terminal (between B
and B) is short-circuited and thetemperature is indicated as 0°C(32°F), this instrument is normal andthe sensor may be burn out.
• For DC voltage (0 to 1 V DC)
If the input terminals of this
instrument are short-circuited andthe scaling low limit is indicated, this
instrument is normal and the sensor
may be burn out.
• For direct current (4 to 20 mA DC)
If the input terminals of this
instrument input 4 mA DC and thescaling low limit is indicated, this
instrument is normal and the sensor
may be burn out.
• For DC voltage (1 to 5 V DC)
If the input terminals of this
instrument input 1 V DC and thescaling low limit is indicated, this
instrument is normal and the sensor
may be burn out.

Problem"1: Error" is set in B5:
