WCL-13A (C5)COMMUNICATION INSTRUCTION MANUAL

No. WCL1CE3 2011.11
This manual contains instructions for communication functions of the WCL-13A.
To prevent accidents arising from the misuse of this controller, please ensure the operator receives thismanual.
Serial communication and Console communication cannot be used together.
When performing Serial communication, remove the USB communication cable (CMB-001) from theUSB port of the PC and Console connector of the WCL-13A.
When performing Console communication, it is not required to remove the Serial communication
cables. However, do not send a command from the master side.

Shielded Wire
Connect only one side of the shielded wire to the FG terminal so that current cannot flow to the shielded
wire. If both sides of the shielded wire are connected to the FG terminal, the circuit will be closed
between the shielded wire and the ground. As a result, current will run through the shielded wire and thismay cause noise.
Be sure to ground the FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted
pair cable.)
Terminator (Terminal Resistor)
The terminator is mounted at the end of the wire when connecting a personal computer with multiple
peripheral devices. The terminator prevents signal reflection and disturbance.
Do not connect a terminator to the communication line because each WCL-13A has built-in pull-up andpull-down resistors instead of a terminator.
Communication converter IF-400 (sold separately) has a built-in terminator.

Command
No response(Fig.4-1)• Response with data
When the master sends the reading command, the slave
responds with the corresponding set value or current status.
• Acknowledgement
When the master sends the setting command, the slave
responds by sending the acknowledgement after theprocessing is terminated.
• Negative acknowledgement
When the master sends a non-existent command or value
out of the setting range, the slave returns a negative
acknowledgement.
• No response
The slave will not respond to the master in the following cases:• Global address (Shinko protocol) is set.
• Broadcast address (Modbus protocol) is set.
• Communication error (framing error, parity error)• Checksum error (Shinko protocol), LRC discrepancy (Modbus
ASCII mode), CRC-16 discrepancy (Modbus RTU mode)

Communication Timing of the RS-485
Master Side (Take note while programming)
Set the program so that the master can disconnect the transmitter from the communication line 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.
If a response to the command is not returned due to communication errors, set the Retry Processing
to send the command again. (Retry twice or more is recommended.)
Slave Side
When the slave starts transmission through a communication line, the slave is arranged so as to provide
an idle status (mark status) transmission period of 1 or more characters before sending the response toensure synchronization on the receiving side.
The slave is arranged so as to disconnect the transmitter from the communication line within a 1 charactertransmission period after sending the response.

5. Shinko Protocol
5.1 Transmission Mode
Shinko protocol is composed of ASCII codes.
Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit

55.3 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 theslaves so that communication errors can be checked.
The ASCII code (hexadecimal) corresponding to the characters which range from the address(instrument number) to that before the checksum is converted to binary notation, and the total value iscalculated.
The lower 2-digits of the total value are converted to 2’s complement, and then to hexadecimal figures,that is, ASCII code for the checksum.
Checksum Calculation Example
CH1 SV1: 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.

Data

Delimiter(CR)

Delimiter(LF)(Fig. 6.2-1)(2) Slave Address
Slave address is an individual instrument number on the slave side, and is set within the range 0 to 95(00H to 5FH).
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 notrespond.
(3) Function CodeThe function code is the command code for the slave to undertake the following action types. (Table 6.2-1)(Table 6.2-1)
Function CodeContents
03 (03H)
Reading the set value and information from slaves
06 (06H)
Setting to slaves
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 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 request message setting 10H to the function code by mistake,slave returns 90H 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. (Table 6.2-2)(Table 6.2-2)
Exception CodeContents
1 (01H)
Illegal function (Non-existent function)
2 (02H)
Illegal data address (Non-existent data address)
3 (03H)
Illegal data value (Value out of the setting range)
17 (11H)
Shinko protocol error code 4 (Status unable to be set)18 (12H)
Shinko protocol error code 5 (During setting mode by keypad operation)(4) Data
Data differs depending on the function code.
A request message from the master is composed of a data item, number of data and setting data.
A response message from the slave is composed of a number of bytes, data and exception codes innegative acknowledgements.
The effective range of data is -32768 to 32767 (8000H to 7FFFH).
(5) Error Check of ASCII Mode
After calculating LRC (Longitudinal Redundancy Check) from the slave address to the end of data,
the calculated 8-bit data is converted to two ASCII characters, and are appended to the end of message.
How to calculate LRC
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.

(5) Error Check of RTU Mode
After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the data, thecalculated 16-bit data is appended to the end of message in sequence from low order to high order.
How to calculate CRC-16
In the CRC-16 system, the information is divided by the polynomial series. The remainder is added to theend of the information and transmitted. The generation of a polynomial series is as follows.
(Generation of 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 fixedvalue (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.

7. Communication Command Table

Data
Note on Setting, Reading Command• The data (set value, decimal) is converted to hexadecimal figures. A negative number is represented by
2's complement.
• When connecting plural slaves, the address (instrument number) must not be duplicated.
Setting Command• Setting range of each item is the same as that of keypad operation.
• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used.
• It is possible to set values with the setting command of the communication function even when the set
value is locked.
• Even if options are not added, setting items for options is possible using the setting command. However,they will not function.
• The instrument numbers and communication speed of the slave cannot be set by communication
function.
• When sending a command by Global address [95 (7FH)], the same command is sent to all the slavesconnected. However, the response is not returned.
• Up to 1,000,000 (one million) entries can be stored in memory.
If the number of settings exceeds the limit, the data will not be saved. So frequent transmission via
communication is not recommended.
Reading Command• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point isused for a response.

Notes on Programming Monitoring Software
How to speed up the scan time
When monitoring plural units of WCL-13A, set the program so that the requisite minimum pieces of datasuch as PV (CH1: 0080H, CH2: 0090H), Output MV (CH1: 0081H, CH2: 0091H), status flag (CH1:0083H, CH2: 0093H), etc. can be read. 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.
How to read the set value change by the front keypad operation
If any set value is changed by keypad operation, the WCL-13A sets the [Status flag (CH1: 0083H, CH2:0093H) 215: Change in key operation] to [Yes (1)].
There are 2 methods of reading the set value change by the front keypad as follows.
Reading method 1(1) On the software side, check that [Status flag (CH1: 0083H, CH2: 0093H) 2 15: Change in key
operation] has been set to [Yes (1)], then read all set values.
(2) Clear the [Status flag (CH1: 0083H, CH2: 0093H) 215: Change in key operation], by setting the [Keyoperation change flag clearing (007FH)] to [Clear change flag (0001H)].
If [Key operation change flag clearing (007FH)] is set to [Clear change flag (0001H)] during thesetting mode of the WCL-13A, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H,
Modbus protocol) will be returned as a negative acknowledgement. And [Status flag (CH1: 0083H,
CH2: 0093H) 215: Change in key operation] cannot be cleared. Set a program so that all set values
can be read when acknowledgement is returned.
Reading method 2(1) On the software side, check that [Status flag (CH1: 0083H, CH2: 0093H) 2 15: Change in key
operation] has been set to [Yes(1)], then set the [Key operation change flag clearing (007FH)] to[Clear change flag (0001H)].
(2) Set the program depending on the acknowledgement or negative acknowledgement as follows.
When acknowledgement is returned;
Consider it as settings completed, and read all set values.
When Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol) is returned
as a negative acknowledgement;
Consider it as still in setting mode, and read the requisite minimum pieces of data such as PV(CH1: 0080H, CH2: 0090H), Output MV (CH1: 0081H, CH2: 0091H), status flag (CH1: 0083H,
CH2: 0093H), etc. then return to step (1).
Thus, programs which do not affect the scan time can be created using the methods described above,even if set values on the monitoring software will not be updated until settings are complete.
How to read PID parameters after AT finishes
The WCL-13A sets [Status flag (CH1: 0083H, CH2: 0093H) 213: AT/Auto-reset] to [(1) During
AT/Auto-reset] while AT is performing. After AT is finished, PID parameters are updated.
On the software side, read the parameters such as P, I, D, ARW after checking that [Status flag (CH1:0083H, CH2: 0093H) 213: AT/Auto-reset] has been set to [OFF (0)].
Note when sending all set values at one time
• When changing alarm type during Alarm 1 type selection (CH1: 0021H, CH2: 0071H), Alarm 1 value willrevert to “0”. First, send the selected alarm type, then send the alarm value.
This will be the same with Alarm 2, Alarm 3 and Alarm 4.

• When changing input type during Input type selection (CH1: 0010H, CH2: 0060H), set values such as SV,
proportional band, Alarm value, etc. will be initialized. First, send the selected input type, then send otherset values.

9. Troubleshooting
If any malfunctions occur, refer to the following items after checking that power is being supplied to themaster and the slave.
• Problem: Communication failure
Check the following
Make sure that communication connector is securely connected.
Check that wiring of the communication connector is correct.
Burnout or imperfect contact on the communication cable and the connector.
Communication speed of the slave does not coincide with that of the master.
The data bit, parity and stop bit of the master do not accord with those of the slave.
The instrument number (address) of the slave does not coincide with that of the command.
The instrument numbers (addresses) are duplicated in multiple slaves.
Make sure that the program is appropriate for the transmission timing.

• Problem: Although communication is occurring, the response is 'NAK'.
Check the following
Check that a non-existent command code has not been sent.
The setting command data exceeds the setting range of the slave.
The controller cannot be set when functions such as AT are performing.
The WCL-13A is in the front keypad operation setting mode.
For all other malfunctions, please contact our main office or dealers.
