ShieldConnect only one side of the shield to the FG or GND terminal so that current
cannot flow through the shield. If both sides of the shield are connected to the
FG or GND terminal, the circuit will be closed between the shield and the ground.
As a result, current will run through the shield and this may cause noise.
Be sure to ground FG and GND terminals.

7. Communication procedure
Communication starts with command transmission from the host computer (hereafter
Master) and ends with the response of the NCL-13A (hereafter Slave).
• Response with data
MasterSlave
Reading command
Response data

When the master sends the reading
command, the slave responds with thecorresponding setting value or current
status.

• Acknowledgement
MasterSlave
When the master sends the settingcommand, the slave responds by sending
a acknowledgement after the processing
is terminated.

Setting command
Response data

• Negative acknowledgement
MasterSlave

Non-existent commandor data out of thesetting range

When the master sends non-existentcommand or a value outside the setting
range, the slave returns a negative
acknowledgement.

Negative acknowledgement• No response
MasterSlave
Global address is set.
Framing error orchecksum error is
occurred.
No response

The slave will not respond to the master
when global address is set, or when there
is a framing error or checksum error (forShinko protocol), or when LRC discrepancy(for Modbus protocol ASCII mode) or CRC
discrepancy (for Modbus protocol RTU mode)is detected.

(Fig. 7-1)
21

Communication timing of the RS-485 (C5 option)
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 ormore characters before sending the response to ensure the synchronization on thereceiving 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.
Master side (Notice on programming)
Set the program so that the master can disconnect the transmitter from the communicationline within a 1 character transmission period after sending the command in
preparation for reception of the response from the slave.
To avoid the collision of transmissions between the master and the slave, send the next
command after carefully checking that the master received the response.

8. Communication protocol
8.1 Shinko protocol
8.1.1 Transmission mode
Shinko protocol is composed of ASCII codes.

8.1.3 Checksum calculation
Checksum is used to detect receiving errors in the command or data.
Set the program for the master side as well to calculate the checksum of the response
data from the slaves so that the communication errors can be checked.
The ASCII code (hexadecimal) corresponding to the characters which range from theaddress to that before the checksum is converted to binary notation, and the total
value is calculated.
The lower 2-digits of the total value are converted to 2’s complements and then tohexadecimal figures, that is, ASCII codes for the checksum.
Checksum calculation example
SV: 600 (0258H)
Address (instrument number): 0 (20H)• 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa.
• 2’s complement: Add 1 to 1’s complement.

8.1.4 Contents of the command
Notes on the setting command and reading command• Although the options are not applied, setting the optional items is possible by thesetting command. However, they will not function.
• The memory can store up to 1,000,000 (one million) entries.
If the number of setting times exceeds the limit, it cannot memorize the data.
So frequent transmission via communication is not recommended.
• When connecting plural slaves, the address (instrument number) must not be
duplicated.
• When sending a command by Global address [95 (7FH)], the same command issent to all the slaves connected. However, the response is not returned.
• The instrument number and communication speed of the slave cannot be set bycommunication function.
Setting command• For the settable range, refer to the Communication command table of this manual.
• All commands are composed of ASCII.
• The data (setting value, decimal) is converted to hexadecimal figures, and ASCII is
used.
Negative numbers are represented by 2's complement. When the data (setting
value) has a decimal point, the whole number without a decimal point is used.
Reading command• All commands are composed of ASCII.
• The data (setting value, decimal) is converted to hexadecimal figures, and ASCII is
used.
Negative numbers are represented by 2's complement. When the data (setting
value) has a decimal point, the response is returned as a whole number without adecimal point.

8.2 Modbus protocol
8.2.1 Transmission mode
There are 2 transmission modes (ASCII and RTU) in Modbus protocol.
8.2.2 ASCII mode
Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order(4-bit) out of 8-bit binary data in the command is transmitted as ASCII characters.
Data format

Data interval : 1 second or less
(1) Message configuration
ASCII mode message is configured to start by [: (colon)(3AH)] and end by [CR(carriage return) (0DH) + LF (Line feed)(0AH)]. See (Fig. 8.2.2-1).

(Fig. 8.2.2-1)
Slave address
Slave address is an individual instrument number on the slave side and is set within
the range 00H to 5FH (0 to 95).
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 00H (broadcast address) can identify all the slaves. However slaves
do not respond.
Function code
The function code is the command code that makes the slave to undertake thefollowing action types (Table 8.2.2-1).
(Table 8.2.2-1)
Function code
Contents
03 (03H)
Reading the setting value and information from slaves
06 (06H)
Setting to slaves26

A 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 the master.
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, when the master sends a request message setting 10H to function
code by mistake, slave returns 90H by setting the MSB to 1, because the former is
an illegal function.)
For negative acknowledgement, exception code (Table 8.2.2-2) below is set to thedata of response message and returned to the master in order to inform it that whatkind of error has occurred.
(Table 8.2.2-2)
Exception code

17 (11H)

Contents
Illegal function (Non-existent function)
Illegal data address (Non-existent data address)
Illegal data value (Value outside the setting range)
Shinko error code 4 (Unsettable status: During AT, etc.)

Data
Data differs depending on the function code.
A request message from the master is composed of data item, number of data andsetting data.
A response message from the slave is composed of number of bytes, data andexception code in negative acknowledgement.
Only one piece of data can be dealt with per message.
Therefore the number of data for ASCII mode is fixed as (30H 30H 30H 31H).
Effective range of data is –32768 to 32767 (8000H to 7FFFH).
(2) ASCII mode error check
After calculating LRC (Longitudinal Redundancy Check) from the slave address tothe end of data, the calculated 8-bit data is converted to two ASCII characters andare appended to the end of the message.
How LRC is calculated
1 Create a message in RTU mode.
2 Add all the values from the slave address to the end of data.
This is assumed as X.
3 Make a complement for X (bit reverse). This is assumed as X.
4 Add a value of 1 to X. This is assumed as X.
5 Set X as an LRC to the end of the message.
6 Convert the whole message to ASCII characters.
(3) ASCII mode message example

Data
Data differs depending on the function code.
A request message from the master side is composed of data item, number of dataand setting data.
A response message from the slave side is composed of number of bytes, data andexception code in negative acknowledgement.
Only one piece of data can be dealt with per message. Therefore the number of data
for RTU mode is fixed as 1 (0001H).
Effective range of data is –32768 to 32767 (8000H to 7FFFH).
(2) RTU mode error check
After calculating CRC-16 (Cyclic Redundancy Check) from the slave address tothe end of data, the calculated 16-bit data is appended to the end of message insequence from low order to high order.
How CRC is calculated
In the CRC system, the information is divided by a polynomial series.
The remainder is added to the end of the information and then transmitted.
The generation of the polynomial series is as follows.
(Generation of the polynomial series: X16 + X 15 + X 2 + 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 last data.
9 Set X as CRC-16 to the end of message in sequence from low order to high order.

Setting data
• When the data (setting value) has a decimal point, the decimal point is removed.
The data is represented as a whole number, and expressed in hexadecimal figures.
Data item(*1) When the alarm action type is changed during Alarm 1, 2, 3, 4 action selection, thealarm setting value returns to the default value.
The alarm output (A1) and status flag (A1, A2, A3, A4) are also initialized.
(*2) Selects whether to turn the control output (OUT1) and cooling output (OUT2) ON or
OFF when the PV goes outside the control range.
(*3) In the case High limit alarm with standby, Low limit alarm with standby or High/Low
limit alarm with standby is selected during Alarm action selection, and when alarm
output is on, the alarm status returns to the standby again by selecting (0001H:
Alarm status flag and standby reset), and the alarm status flag is also initialized.
Note
Setting of OUT1 (OUT2) high limit or low limit value during standby or warm-up status
is not effective.

10. Running10.1 Setup

NoticeBefore setup, check communication parameter setting, mounting andwiring, referring to chapters “4 Communication parameter setting”,“5 Mounting” and “6 Wiring”.
(1) Switch power to the unit ON.
The power indicator (POW) lights up and the unit will be in command waiting
status.
(2) Set up the unit.
The input type, alarm action and control action, etc. have to be set according to theusers’ using conditions before using this unit.
Perform setup from the host computer through communication function.
Shaded portions
are setup items.
If the NCL-13A is incorporated into other industrial equipment after setting has been
completed, or if the user’s specification is the same as the default value of theNCL-13A, then it is not necessary to set up.
Proceed to Section “10.2 Start running”.

Notice• Perform the auto-tuning during the trial run.
• Auto-tuning can be performed in PID action with the status of Control Allowed.
• During PID auto-tuning, none of the setting items can be set.
If setting command is sent, Negative acknowledgement [NAK: Error code 4(Unsettable status)] is returned.
• If auto-tuning is canceled during process, P, I, D and ARW values return tovalues set before the auto-tuning was performed.
If auto-tuning has not finished 4 hours after it has started, it is automaticallyfinished.
• If power failure occurs during PID auto-tuning, the auto-tuning stops.

Auto-tuning (AT)In order to decide each value of P, I, D and ARW automatically, the auto-tuning
process should be made to fluctuate to obtain an optimal value.
(1) In the case of a large difference between the setting value and processing
temperature as the temperature is rising.
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20
lower than the setting value.

11. Control action explanation
11.1 P, I, D and ARW(1) Proportional band (P)Proportional action is the action which the control output varies in proportion to thedeviation between the setting value and the processing temperature.
If the proportional band is narrowed, even if the output changes by a slight variationof the processing temperature, better control results can be obtained as the offset
decreases.
However, if the proportional band is narrowed too much, even slight disturbances
may cause variation in the processing temperature, control action changes to
ON/OFF action and the so-called hunting phenomenon occurs.
Therefore, when the processing temperature comes to the balanced position near
the setting value and a constant temperature is maintained, the most suitable value
is selected by gradually narrowing the proportional band while observing the control
results.
(2) Integral time (I)Integral action is used to eliminate offset. When the integral time is shortened, thereturning speed to the setting point is accelerated. However, the cycle of oscillationis also accelerated and the control becomes unstable.
(3) Derivative time (D)Derivative action is used to restore the change in the processing temperatureaccording to the rate of change. It reduces the amplitude of overshoot and undershootwidth.
If the derivative time is shortened, restoring value becomes small, and if the derivative
time is extended, an excessive returning phenomenon may occur and the control
system may oscillate.
(4) Anti-reset windup (ARW)
ARW (Anti-reset windup) prevents overshoot caused by the integral action. The smaller
the ARW value, the less the overshoot caused by the integral action in the transition
status, however it takes time until stabilization.
When setting ARW manually, set it to the closest MV (manipulated variable) when thecontrol is stabilized.
If MV is not determined, perform trial run at default value (50%)
P, I, D and ARW values are automatically set if auto-tuning is performed.

AlarmAlarm 1 output
When Alarm 1 action is set as Energized, the alarm action point is set bydeviation from the SV (except Process value alarm).
When the input goes out of the range, the Event output turns ON or OFF (High/Low limit range alarm).
When the alarm action is set as Deenergized, the output acts conversely.
Alarm typeOne alarm can be selected from a choice of: High limit alarm, Low limit alarm,
High/Low limits alarm, High/Low limit range alarm, Process high alarm, Process low
alarm, High limit alarm with standby, Low limit alarm with standby, High/Low limits
alarm with standby and No alarm action (10 types). (Default value: No alarm action)
Alarm 1 output Energized or Deenergized can be selected as well.
Alarm 1 uses common output terminals with Loop break alarm, Heater burnout
alarm/Actuator short circuit alarm (W, W3 option).
When Heating/Cooling control output (DC option) is applied, Event output becomescooling output (OUT2). Therefore, Alarm 1, Loop break alarm and Heater burnout
alarm/Actuator short circuit alarm cannot be outputted.

14. Troubleshooting
If any malfunction occurs, refer to the following items after checking the power supply tothe master and the slave (NCL-13A).
14.1 Communication
Problem
Communication failure

Though it is able tocommunicate, theresponse is “NAK”.

14.2 Control
ProblemPV (Process variable)
does not rise.

The control output
remains in an ON
status.
The control output
remains in an OFF
status.

Presumed cause and solution• The connection or wiring of communication is not secure.
• Burnout on the communication cable or imperfect contact
with the connector.
• Communication speed of the slave does not coincide withthat of the master.
• The data bit, parity and stop bit of the master do notaccord with those of the slave.
• The instrument number (address) of the slave does notcoincide with that of the command• The instrument number (address) of the slave is duplicatedin multiple slaves• Check whether a non-existent command code has been
sent.
• The setting command data goes outside the setting rangeof the slave.
• The unit cannot be set when functions such as AT is
performing.

Presumed cause and solution• The sensor is out of order.
Replace the sensors.
• Sensor is not securely connected to the instrument input
terminals, or actuator is not securely connected to the
instrument output terminal.
• Ensure that the wiring of sensor terminals or actuatorterminals are correct.
• OUT1 (OUT2) low limit value is set to 100% or higher.
Set it to a suitable value.
• OUT1 (OUT2) high limit value is set to 0% or less.
Set it to a suitable value.

6214.3 PV
Problem
PV is high.

PV is low.

The indication of
PV display isabnormal or unstable.

Presumed cause and solution• Thermocouple, RTD or DC voltage (0 to 1V DC) is burnt
out.
Change each sensor.
How to check whether the sensor is burnt out[Thermocouple]
If the input terminal of the instrument is shorted and if
a value around room temperature is indicated, theinstrument is likely to be operating normally, however, thesensor may be burnt out.
[RTD]
If approximate 100 of resistance is connected to the
input terminals between A-B of the instrument andbetween B-B is shorted, and if approximate 0 (32 ) is
indicated, the instrument is likely to be operating normally,
however, the sensor may be burnt out.
[DC voltage (0 to 1V DC)]If the input terminal of the instrument is shorted and if a
scaling low limit value is indicated, the instrument is likely
to be operating normally, however, the signal wire may bedisconnected.
• Check whether the input signal wires of thermocouple, RTD or
DC voltage (0 to 1V DC) are securely connected to the
instrument input terminals.
Ensure that the sensor terminals are connected to the
instrument input terminals securely.
• Check whether the input signal source for DC voltage (1 to
5V DC) or DC current (4 to 20mA DC) is disconnected.
How to check whether the input signal wire is
disconnected[DC voltage (1 to 5V DC)]If the input to the input terminals of the instrument is 1V
DC and if a scaling low limit value is indicated, theinstrument is likely to be operating normally, however, thesignal wire may be disconnected.
[DC current (4 to 20mA DC)]If the input to the input terminals of the instrument is 4mA
DC and if a scaling low limit value is indicated, theinstrument is likely to be operating normally, however, thesignal wire may be disconnected.
• Check whether the input signal wire for DC voltage (1 to 5VDC) or DC current (4 to 20mA DC) is securely connectedto the instrument input terminals.
• Check whether the polarity of thermocouple orcompensating lead wire is correct.
Check whether codes (A, B, B) of the RTD agree with the
instrument terminals.
Ensure that they are wired properly.
• The sensor input or temperature unit ( or ) setting
is improper.
Set the sensor input and the temperature unit properly.
• Sensor correcting value is unsuitable.
Set it to a suitable value.
63

The indication of
PV display isabnormal or unstable.

• AC may be leaking into the sensor circuit.
Change the sensor for the ungrounded type.
• There may be equipment that interferes with or makes
noise near the control unit.
Keep equipment that interferes with or makes noiseaway from the control unit.
