No. ACDR11CE1 2008.01
This manual contains instructions for communication functions of the ACD-13A, ACR-13A.
Serial communication and Console communication cannot be used together.
When performing Serial communication, remove the exclusive cable (CMB) from the USB port of the PC and
console connector of the ACD-13A, ACR-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.

When using communication converter IF-400
• D-sub 9-pin connector
(Fig. 2-3)
• D-sub 25-pin connector
(Fig. 2-4)
Shielded wire
Connect only one side of the shielded wire to the FG or GND terminal so that current cannot flow to the
shielded wire. If both sides of the shielded wire are connected to the FG or GND terminal, the circuit will be
closed between the shielded wire and the ground. As a result, current will run through the shielded wire and
this may cause noise.
Be sure to ground FG or GND terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted 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 a personal computer with multiple
peripheral devices. The terminator prevents signal reflection and disturbance.
Do not connect terminator with the communication line because each ACD/ACR-13A has built-in pull-up
and pull-down resistors instead of a terminator.

4. Communication procedure
Communication starts with command transmission from the host computer (hereafter Master) and
ends with the response of the ACD/ACR-13A (hereafter Slave).
• 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 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.
• Communication error (framing error, parity error)
• Checksum error (Shinko protocol), LRC discrepancy (Modbus ASCII
(Fig.4-1) mode), CRC-16 discrepancy (Modbus RTU mode)
Communication timing of the RS-485
Master side (Notice on 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.
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 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
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 with hexadecimal number.
The negative numbers are represented with 2's complement.
Numerals written below the command represent number of characters.

Header : Control code to represent the beginning of the command or the response.
ASCII codes are used.
Setting command, Reading command : STX (02H) fixed
Response with data, Acknowledgement : ACK (06H) fixed
Negative acknowledgement : NAK (15H) fixed
Instrument number (Address): Numbers by which the master discerns each slave.
Instrument number 0 to 94 and Global address 95.
ASCII codes (20H to 7FH) are 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.
Sub address : 20H fixed
Command type : Code to discern Setting command (50H) and Reading command (20H)
Data item : Data classification of the command object.
Composed of hexadecimal 4 digits, using ASCII.
(Refer to “7. Communication command table”.)
Data : The contents of data (set value) differs depending on the setting command.
Composed of hexadecimal 4 digits, using ASCII.
(Refer to “7. Communication command table”.)
Checksum : 2-character data to detect communication errors. (Refer to “5.3 Checksum calculation”.)
Delimiter : Control code to represent the end of command
ASCII code ETX (03H) fixed
Error code : Represents an error type with ASCII codes.

2 (32H)-----Not used
3 (33H)-----Setting outside the setting range
4 (34H)-----Unsettable status (e.g. AT is performing)
5 (35H)-----During setting mode by keypad operation
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 to that before
the checksum is converted to binary notation, and the total value is calculated.
The lower 2-digit of the total value are converted to 2’s complements, and then to hexadecimal figures,
that is, ASCII code 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 complements.

6. Modbus protocol
6.1 Transmission mode
There are 2 transmission modes (ASCII and RTU) in Modbus protocol.
6.2 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 command is transmitted as ASCII characters.
Data format Start bit : 1 bit
Data bit : 7 bits (8 bits) Selectable
Parity : Even (Odd, No parity) Selectable
Stop bit : 1 bit (2 bits) Selectable
Error detection : LRC (Longitudinal Redundancy Check)
Data interval : 1 second or less (Max.1sec of interval between characters)
(1) Message configuration

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.
Function code
The function code is the command code for the slave to undertake the following action types.
Function code Contents
03 (03H) Reading the set value and information from slaves
06 (06H) Setting to slaves
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.
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 error code 4 (Unsettable status, e.g. AT is performing)
18 (12H) Shinko error code 5 (During setting mode by keypad operation)
Data
Data differs depending on the function code.
A request message from the master is composed of 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 in negative
acknowledgements. The number of data to be dealt with in one message is “1”.
Therefore the number of data is fixed as (30H)(30H)(30H)(31H).
Effective range of data is -32768 to 32767 (8000H to 7FFFH).
Error check:2-character data to detect communication errors.
Refer to “(2) Error check of ASCII mode”. (p.8)

8
(2) 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.
(3) Message example of ASCII mode
Numerals written below the command represent number of characters.

Data
Data differs depending on the function code.
A request message from the master side is composed of data item, number of data and setting data.
A response message from the slave side is composed of a number of byte, data and exception codes
in negative acknowledgements.
The number of data to be dealt with in one message is “1”. Therefore the number of data is fixed as (0001H).
The number of response byte is (02H).
Effective range of data is –32768 to 32767 (8000H to 7FFFH).
Error check: 16 bit data to detect communication errors. Refer to “(2) Error check of RTU mode”. (p.10)

(2) Error check of RTU mode
After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of 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
In the CRC system, the information is divided by the polynomial series. The remainder is added to the
end of the information and transmitted. The generation of 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 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.

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.
• Do not use the unused data items such as 0000H, 000CH. If they are used, negative acknowledgement will
be returned or communication errors may occur.
• Modbus protocol uses Holding Register address. For Holding Register address, data item of Shinko protocol
is converted to decimal figures, and to which offset of 40001 is added.
(e.g.) In the case of “0001H: SV [Set value memory number 1 (SM1)]”, data item on the message to be sent is
0001H, however, Holding Register address of the Modbus protocol is 40002 (1+40001).
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.
• If the alarm type is changed during Event output EVT1 allocation (0060H) to Event output EVT5 allocation
selection (0064H), the alarm value will revert to “0”. Also alarm output status will be initialized.
• It is possible to set the set value with the setting command of the communication function even when the set
value is locked.
• Although the options are not applied, setting the items for the 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 slaves
connected. However, the response is not returned.
• The memory can store up to 1,000,000 (one million) entries.
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 is
used for a response.
Negative acknowledgement
The slave will return Error code 1 (31H) (Shinko protocol) or Exception code 1 (01H) (Modbus protocol)
in the following cases.
• If AT/Auto-reset (0010H) is selected while control is in PI action or in ON/OFF action.
• When Manual MV (00D3H) is read during automatic control.
The slave will return Error code 4 (34H) (Shinko protocol) or Exception code 17 (11H) (Modbus
protocol) in the following cases.
• When SV setting (00D0H) of current Set value memory number is performed during AT or program control.
• When manual MV (00D3H) is set during automatic control.
