Shield wire
Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of theshield wire are connected to the FG terminal, the circuit will be closed, resulting in a ground loop.
This may cause noise.
Be sure to ground the FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use atwisted pair cable.)
Terminator (Terminal resistor)
Communication converter IF-400 (sold separately) has a built-in terminator.
The terminator is mounted at the end of the wire when connecting multiple peripheral devices to apersonal computer. The terminator prevents signal reflection and disturbance.
Do not connect a terminator to the communication line because the JCL-33A has built-in pull-up
and pull-down resistors.

-3-3. Setting Communication Parameters

• Response with data
When the master sends the Read command, the slave
responds with the corresponding set value or current status.
• Acknowledgement
When the master sends the Write 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 (C5 option)
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 within a
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 tosend 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) of 1 character transmission period 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.

-5-5. Shinko Protocol
5.1 Transmission Mode
Shinko protocol is composed of ASCII.
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 command is transmitted as ASCII characters.
Data format
Start bit: 1 bit
Data bit: 7 bits
Parity: Even
Stop bit: 1 bit
Error detection: Checksum
5.2 Command Configuration
All commands are composed of ASCII.
The data (set value, decimal number) is represented by a hexadecimal number.
The negative numbers are represented by 2's complement.
Numerals written below the command represent number of characters.

Instrument number (Address): Numbers by which the master discerns each slave.
Instrument number 0 to 94 and Global address 95.
ASCII (20H to 7FH) is used by adding 20H to instrument numbers 0 to 95 (00H to 5FH).
95 (7FH) is called Global address, which is used when the same command is sent to
all the slaves connected. However, the response is not returned.

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 to that
before the checksum is converted to binary notation, and the total value is calculated.
The lower one byte of the total value is converted to 2’s complement, and then to hexadecimal
numbers, that is, ASCII code for the checksum.
• 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa.
• 2’s complement: Add 1 to 1’s complement.
[Example of checksum calculation]
Write SV1 to 600 (0258H). See (Fig. 5.3-1).

6. Modbus Protocol
6.1 Transmission Mode
There are 2 transmission modes (ASCII and RTU) in Modbus protocol.
6.1.1 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 command is transmitted as ASCII characters.
Data format
Start bit: 1 bit
Data bit: 7 bits (Selectable)
Parity: Even (No parity, Odd) (Selectable)
Stop bit: 1 bit (2 bits) (Selectable)
Error detection : LRC (Longitudinal Redundancy Check)
6.1.2 RTU Mode
8-bit binary data in command is transmitted as it is.
Data format Start bit: 1 bit
Data bit: 8 bits
Parity: No parity (Even, Odd) (Selectable)
Stop bit: 1 bit (2 bits) (Selectable)
Error detection: CRC-16 (Cyclic Redundancy Check)6.2 Data Communication Interval
6.2.1 ASCII ModeNo communication interval limit between characters
6.2.2 RTU Mode
1.5 character transmission times or less(Communication speed 2400, 4800, 9600, 19200 bps: 1.5 character transmission times,
Communication speed 38400 bps: 750 s)
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 JCL-33A assumes thattransmission from the master is finished, which results in a communication error, and will not
return a response.
6.3 Message Configuration
6.3.1 ASCII Mode
ASCII mode message is configured to start by Header [: (colon) (3AH)] and end by Delimiter[CR (carriage return) (0DH) + LF (Line feed) (0AH)].

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 addressin the response message.
Slave address 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.
(Table 6.3-1)
TypeFunction Code Sub-Function CodeContentsReads
asingleormultiple piece(s) of
03 (03H)
data from slave(s).
Data access
06 (06H)
Writes a single piece of data to slave(s).
16 (10H)
Writes multiple pieces of data to slave(s).
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 tothe 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 forthe 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 (Table 6.3-2) 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 6.3-2)
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)
Shinko protocol error code 4
17 (11H)(Status unable to be written. (e.g.) AT is performing.)
Shinko protocol error code 5
18 (12H)(During setting mode by keypad operation)(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 codesin negative acknowledgements, corresponding to the request message.
The effective range of data is -32768 to 32767 (8000H to 7FFFH).
Refer to Section “7. Communication Command Table” (pp.21 - 29).
(4) Error CheckASCII 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.

-13-

RTU Mode
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 + 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 thefixed 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.

7.3 Data
7.3.1 Notes about Write/Read Command• The data (set value, decimal) is converted to a hexadecimal number.
Negative numbers are represented in 2's complement.
• When connecting multiple slaves, the address (instrument number) must not be duplicated.
• Do not use undefined Data items. If they are used, negative acknowledgement will be returned or arandom value will be written or read, resulting in malfunction.
• Modbus protocol uses Holding Register addresses. The Holding Register addresses are created asfollows. A Shinko command Data item is converted to decimal number, and the offset of 40001 is
added. The result is the Holding Register address.
Using Data item 0001H (SV1) as an example: Data item in the sending message is 0001H, however,
Modbus protocol Holding Register address is 40002 (1 + 40001).
7.3.2 Write Command• Setting range of each item is the same as that of keypad operation.
• When data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point isused.
• Writing via software communication will be possible even in the set value lock status.
• If the alarm type is changed in [A1 type (0023H or 0006H)] or in [A2 type (0024H or 0007H)], A1 valueor A2 value will default to 0 (zero). Alarm output status will also be initialized.
• Even if options are not ordered, writing via software communication will be possible.
However, their command contents will not function.
• The Communication protocol, Instrument Numbers, Communication Speed, Parity and Stop bit of theslave cannot be written by software communication. They can only be set via the keypad.
• When writing a command by Global address [95 (7FH), Shinko protocol] or Broadcast address [00H,
Modbus protocol], the same command is sent to all the slaves connected. However, the response is
not returned.
• Up to 1,000,000 (one million) entries can be stored in non-volatile IC memory.
If the number of writings exceeds the limit, the data will not be saved. So, do not change the set values
frequently via communication. (If a value written via software communication is the same as the value
before writing, the value will not be written in non-volatile IC memory.)
7.3.3 Read Command• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point
is used for a response.
7.4 Negative Acknowledgement
The slave will return Error code 1 (31H, Shinko protocol) or Exception code 1 (01H, Modbus protocol)
during PI control or ON/OFF control action in the following case:• When AT Perform/Cancel (0003H or 00E2H) is read or written
The slave will return Error code 4 (34H, Shinko protocol) or Exception code 17 (11H, Modbus protocol)in the following cases:• While AT is cancelled, and if 0003H or 00E2H (AT Perform/Cancel) is written to 0000H (AT Cancel)• While AT is performing, and if 0003H or 00E2H (AT Perform/Cancel) is written to 0001H (ATPerform)-30-

7.5 Notes on Programming Monitoring Software
7.5.1 How to Speed up the Scan Time
When monitoring multiple units of the controller, set the program so that the requisite minimum piecesof data such as Data item 0080H or 0100H (PV), Data item 0081H or 0101H (OUT1 MV), Data item
0085H or 0106H (Status flag), 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.
7.5.2 How to Read the Set Value Changes Made by Front Keypad Operation
If any set value is changed by the keypad operation, the controller sets 0085H or 0106H (Status flag,
215: Change in key operation) to “1 (Yes)”.
There are 2 methods of reading the set value changes made by front keypad.
(1) Reading method 1
1 On the monitoring software side, check that 0085H or 0106H (Status flag, 2 15: Change in key
operation) has been set to “1 (Yes)”, then read all set values.
2 Clear 0085H or 0106H (Status flag, 215: Change in key operation), by writing Data item 0070H or
00FFH (Key operation change flag clearing) to 0001H (Clear key operation change flag).
If 0070H or 00FFH (Key operation change flag clearing) is written to 0001H (Clear key operation
change flag) during the setting mode of the controller, Error code 5 (35H, Shinko protocol) or
Exception Code 18 (12H, Modbus protocol) will be returned as a negative acknowledgement. And
0085H or 0106H (Status flag, 215: Change in key operation) cannot be cleared.
Set a program so that all set values can be read when a negative acknowledgement is returned.
3 Read all set values again after acknowledgement is returned.
(2) Reading method 2
1 On the monitoring software side, check that 0085H or 0106H (Status flag, 2 15: Change in key
operation) has been set to “1 (Yes)”, then write 0070H or 00FFH (Key operation change flagclearing) to 0001H (Clear key operation change flag).
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 0080H
or 0100H (PV), 0081H or 0101H (OUT1 MV), 0085H or 0106H (Status flag), 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.
7.5.3 How to Read PID Parameters after AT Finishes
While AT is performing, this controller sets 0085H or 0106H (Status flag, 211: During AT) to “1 (During
AT)”.
After AT is finished, PID parameters are updated.
On the monitoring software side, check that 0085H or 0106H (Status flag, 211: During AT) has been set
to “0 (OFF)”, then read parameters such as P, I, D, ARW.
7.5.4 Note When Sending All Set Values Simultaneously• When changing alarm types at 0023H or 0006H (A1 type), 0024H or 0007H (A2 type), A1 value or A2
value will default to 0 (zero).
First, send the selected alarm type, then send each alarm value.
• When changing input types at 0044H or 0002H (Input type), the set values such as SV1, OUT1
proportional band, A1 value will be initialized.
First, send the selected input type, then send other set values.

10. Troubleshooting
Check that power is being supplied to the master and slave that customers use. If communication failure
still occurs, check the following.
Problem
Communication
failurePossible Cause
Communication cable is not securely
connected, or is disconnected/defective.
Incorrect wiring of the communication
cable and/or connector
Imperfect contact between thecommunication cable and the connector,
or between the communication connector
and instrument port
Communication speed of the slave does
not match that of the master.

The data bit, parity and stop bit of themaster do not correspond to those of
the slave.
The instrument number (address) of theslave does not correspond to that of
the command.
The instrument numbers (addresses) are
duplicated in multiple slaves.

Make sure that the program isappropriate for the transmission timing.
Although communication is occurring, theresponse is negative
acknowledgement.

A non-existent command code has been
sent.
The Write command data exceeds thesetting range of the slave.
The controller cannot be written whenfunctions such as AT are performing.
The instrument is in front keypad
operation setting mode.
