Shield Wire
Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of the shield wire are connected to the FG terminal, the circuit will be closed, resulting in a ground loop. This may cause noise.
Note: Be sure to ground the FG terminal.

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 a personal computer. The terminator prevents signal reflection and disturbance. Do not connect a terminator to the communication line because each JIR-301-M has built-in pull-up and pull-down resistors instead of a terminator.
3. Communication Parameters Setting
Set communication parameters in Auxiliary Function Setting Mode 1. To enter Auxiliary Function Setting Mode 1, press the DOWN key and MODE key (in that order) together in PV/SV Display Mode. Press the MODE key 3 times. The unit will move to [Communication protocol]. Use the UP or DOWN key for making a selection or setting values. To register the set data, press the MODE key.

4. Communication Procedure
Communication starts with command transmission from the host computer (hereafter Master), and ends with the response of the JIR-301-M (hereafter Slave).

(Fig. 4-1) • Communication error (framing error, parity error)
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 to send the command again. (It is recommended to execute Retry twice or more.)
• 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 acknowledgement after the processing 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.
• Checksum error (Shinko protocol), LRC discrepancy (Modbus ASCII mode), CRC-16 discrepancy (Modbus RTU mode)
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 or more characters 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. Shinko Protocol
Read data
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 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 in 2's complement. Numerals written below the command represent number of characters.

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 the slaves 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 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.
Checksum calculation example:
A1 value (0001H) is written to 600 (0258H) Address (instrument number): 0 (20H)

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 Mode
No 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 JIR-301-M assumes that transmission 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)]. Data: Max. 2 x 252 characters
Header
(:)
6.3.2 RTU Mode
RTU mode 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 2400, 4800, 9600, 19200 bps: 3.5 character transmission times, Communication speed 38400 bps: 1.75 ms) Data: Max. 252 bytes

(1) 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 not respond.
(2) Function Code
The function code is the command code for the slave to undertake one of the following actions.
(Table 6.3-1)
Type
Data access
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, if 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.
Function Code
03 (03H)
04 (04H)
06 (06H) Writes a single piece of data to slave(s).
16 (10H)
Reads a single or multiple piece(s) of data from slave(s). (Up to 100 pieces of data can be read per command.) Reads status from slave(s). (Up to 100 pieces of data can be read per command.)
Writes multiple pieces of data to slave(s). (Up to 100 pieces of data can be written per command.)
Contents
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 6.3-2)
Exception Code Contents
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 written)
18 (12H) Shinko protocol error code 5
(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 number of bytes, data and exception codes in 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.24 to 31).

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.
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 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 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 step5.

6
XOR is calculated with the next data and X. This is assumed as X.

(1) Slave address
Slave address is an individual instrument number on the slave side, and is set within the range 1 to 95 (01H 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. Diagnostics function is disabled for the Slave address 0 (00H, Broadcast address).

The function code is the command code for the slave to undertake the following action types.
Type Function Code Sub-function Code
08 (08H) 00 (0000H) Echoes back the request message.
Diagnostics
43 (2BH) 14 (0EH) Reads device identification information.
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 0FH to the sub-function code by mistake, slave returns ABH by setting the MSB to 1, because the former is a non-existent sub-function code.
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 Code Contents

2 (02H)
3 (03H)
Illegal function (Non-existent function) Sub-function code is not correct. Illegal data address (Non-existent data address) For function code 43: Object ID is any value other than 00, 01, 02. Illegal data value (Value out of the setting range) For function code 08: Data is less than 1, or has exceeded 100. For function code 43: Read Device ID code is any value other than 01, 04.
(Up to 100 pieces of data can be echoed back per command)

(3) Data
Data differs depending on the function code. For the Function code 08 (08H), a request message from the master side is composed of ‘Sub-function code 2 Bytes (0000H)’ and ‘Data n x 2 Bytes’. [n: Amount of data (Max. 100)] In normal status, a response message from the slave side is the same as the request message.

7.3 Data
7.3.1 Notes about Write/Read Command
• The data (set value, decimal) is converted to hexadecimal figures.
A negative number is represented by 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 a
random value will be written or read, resulting in malfunction.
• Modbus protocol uses Holding Register addresses. The Holding Register addresses are created as
follows. 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 (A1 value or input type) 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 the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is
used.
• Writings via software communication are possible while in Set value lock status.
When Lock 3 (0003H) is selected at Set value lock (0004H or 001EH), the written data will not be saved in the non-volatile memory. Therefore they return to their previous value after power is turned off.
• If any alarm type is changed in [000DH, 000EH, 000FH or 0005H, 0006H, 0007H, 0008H], the alarm
value (0001H, 0002H, 0003H or 0009H, 000AH, 000BH, 000CH) will default to “0”. Also alarm output status will be initialized.
• If Power for 2-wire transmitter (DSB option) is ordered, and if an input type is changed in [0019H or
0001H], acknowledgement will be returned, and the setting data will be discarded.
If the input type is read, the default value (0024H) will be returned as data.
• 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 the
slave cannot be written by software communication. They can only be set via the keypad.
• When Write is executed using the Global address [95 (7FH), Shinko protocol] command or Broadcast
address [0 (00H) Modbus protocol] command, the command is sent to all the connected slaves. However, a response is not returned.
• Up to 1,000,000 (one million) entries can be stored in non-volatile IC memory.
If the number of settings exceeds the limit, the data will not be saved. So, frequent transmission via software communication is not recommended. (If a value written via software communication is the same as the value before the setting, 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 2 (02H, Modbus protocol) in the following case.
• When non-existent data item is read or written.
The slave will return Error code 3 (33H, Shinko protocol) or Exception code 3 (03H, Modbus protocol) in the following case.
• When a value out of the setting range is written.
The slave will return Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol) in the following case.
• During setting mode by keypad operation
7.5 Notes about Programming Monitoring Software
7.5.1 How to Speed up the Scan Time
When monitoring multiple units of JIR-301-M, set the program so that the requisite minimum pieces of data such as PV (0080H or 0100H), Status flag (0081H), status flag 1 (010DH), 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.
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 JIR-301-M sets [Status flag (0081H) or Status flag 1 (010DH) 215: Change in key operation] to [Yes (1)]. There are 2 methods of reading the set value changes made by the front keypad.
Reading Method 1
(1) On the software side, check that [Status flag (0081H) or Status flag 1 (010DH) 215: Change in key
operation] has been set to [Yes (1)], then read all set values.
(2) Clear the [Status flag (0081H) 215: Change in key operation], by writing the [Key operation change
flag clearing (0070H or 00FFH)] to [Clear key operation change flag (0001H)]. If [Key operation change flag clearing (0070H or 00FFH)] is written to [Clear key operation change flag (0001H)] during setting mode of the JIR-301-M, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, Modbus protocol) will be returned as a negative acknowledgement. And [Status flag (0081H) or Status flag 1 (010DH) 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.
Reading Method 2
(1) On the software side, check that [Status flag (0081H) or Status flag 1 (010DH) 215: Change in key
operation] has been set to [Yes (1)], then write the [Key operation change flag clearing (0070H or
00FFH)] to [Clear key operation 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
(0080H or 0100H), Status flag (0081H) or Status flag 1 (010DH), 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.

7.5.3 Note when Sending All Set Values at One Time
• When changing alarm types in [000DH, 000EH, 000FH or 0005H, 0006H, 0007H, 0008H], the alarm value (0001H, 0002H, 0003H or 0009H, 000AH, 000BH, 000CH) will default to “0”. Alarm output status will also be initialized. First, send the alarm type, then send the alarm value.
• When changing input types in [Input type (0019H or 0001H)], set values such as Scaling high limit, Scaling
low limit or alarm value, etc. will be initialized. First, send the input type, then send other set values.
7.6 When Communicating with a PLC
To communicate with a PLC, use a Shinko PLC interface unit SIF-600. No programming is needed for connection. However, Shinko protocol 24H (Multiple pieces of data Read command) and 54H (Multiple pieces of data Write command) are not available for the SIF-600.

9. 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 failure
Check if any of the following have occurred
Connection or wiring of the communication cable is not secure.
Burnout or imperfect contact on the communication cable and the connector.
Communication speed of the slave does not match that of the master.
The data bit, parity and stop bit of the master do not correspond to those of the slave.
The instrument number of the slave does not correspond to that of the command.
The instrument numbers are duplicated in multiple slaves.
Make sure that the program is appropriate for the transmission timing.
Problem: Although communication is occurring, the response is negative acknowledgement.
Check if any of the following have occurred
A non-existent command code has been sent.
The Write command data exceeds the setting range of the slave.
The indicator cannot be write when functions such as AT are performing.
The JIR-301-M is in the front keypad operation setting mode.
