2. COMMUNICATION INTERFACE
ԂCommunication protocol conforms to MODBUS and the protocol can be selected from RTU and
ASCII.
Refer to MODBUS standard specification and commercial reference manuals for details on
MODBUS.
2.1: Data transmission system
Transmission system: half-duplex asynchronous data transfer (polling/selecting)
Transmission distance: Max 500m (results may vary depending on environment)
Connection method: Multi-drop system (max 31 units)
Start bit: 1 bit
Transmission code: ASCII (ASCII mode)
Binary (RTU mode)
Error check: LRC (ASCII mode)
CRC-16 (RTU mode)
2.2: Frame configuration
In RTU mode, frame is composed of message portion only.
In ASCII mode, frame consists of start character ": (colon, 3AH)", message and end character
"CR (carriage return, ODH) + LF (line feed, 0AH)".
RTU mode: message
ASCII mode: : | message | CR | LF
2.3: Message configuration
MODBUS messages are composed of the following in both RTU andASCII modes.
Slave address
Function code
Data
Error check
2.4: Slave address
Slave address can be set from 1-99. Master normally communicates with one slave device. All
slave devices receive any message sent from the master in common, however, only the device
with slave address corresponding to the directive message responds.

2. COMMUNICATION INTERFACE
2.5: Function code
The function code communicates to the slave device what to execute. Function code data is
classified by type below.
Analog setting: each setting information type. Numerical value within 16 bits:
-32768 to 32767
Analog input data: measurement, status and other data. Numerical value within 16 bits.
Code Function Unit MODBUS original function (reference)
03
Read analog settings 16 bit Read content of maintenance register
04
Read analog input data 16 bit Read content of input register
06
Write analog settings 16 bit Write to single maintenance register
2.6: Data
Data configuration varies according to function code.
At the time of request from the master, data is composed of code number, data count, etc. of
target data to be read and written.
Response from the slave consists of data in relation to the request.
Basic MODBUS data is all integers of 16-bit, and the presence or absence of a sign is defined for
each data. Accordingly, by assigning a decimal to another address to convert into an integer or
fixing the decimal position, it is normalized and expressed on scale upper/lower limits.
2.7: Reference number
A reference number is assigned to data and it is necessary for reading and writing the data.
Reference number range is categorized as "analog input data" and "analog setting value"
according to data type.
Data type Reference number Relative number
Analog input data 30001-40000 Reference number -30001
Analog setting value 40001-50000 Reference number -40001
Relative number is the address number used during actual communication.
