4.1 Message frame configuration
The MODBUS message is the configuration like a list shown below.
Due to the MODBUS RTU mode, the message is configured of all the binary data.
Slave address → Refer to [4.2 Slave address: Detector No.]
Function code → Refer to [4.3 Function code]
Data → Refer to [4.4 Data filed]
Error check → Refer to [4.5 Error check]
4.2 Slave address: Detector No.
Program the slave address (the detection number) in 1 to 9 ranges previously by using front key.
The master usually communicates it to 1 slave.
All the connected devices are received the message from the master in common.
However, the only slave in accord with the slave address answers the message.
4.3 Function code
The function code is the implementation command code to a slave (detector).
Each data is the next classification approximately.
(1) Analog input data Measured data, Status etc.
(2) Analog setting value Various kinds setting information such as calibration curve.
(3) Digital setting value Smoothing/Real switching, Preset output ON/OFF etc.

4.4 Data field
4.4.1 Data configuration
The configuration of the data differs by the function code.
The demanded data from the master is configured of the code number (Relative number that
calculates it from [4.4.2 Reference No.]) and data number etc. to the reading and writing of the
object data. The answer from the slave is configured of the demanded data etc.
The basis data of MODBUS is all the integers of 16 bits and the existence or nonexistence of the
mark is prescribed at each data.
4.4.2 Reference No.
"The reference number" of the list shown below is assigned to the data inside IRMA series Infrared
Multi Analyzer detector unit Model for IRMA.
This number is required to the reading and writing of data.
It is classified like the list shown below by the kind of data.
The number appointment in the message is "Relative number" that corresponds to each reference
number.
Kind of data Reference number Relative number
Digital setting value 1 to 10000 (Reference number)－1
Digital input data 10001 to 20000 (Reference number)－10001
Analog input data 30001 to 40000 (Reference number)－30001
Analog setting value 40001 to 50000 (Reference number)－40001
The relative number of the measured value (temperature data) of "reference number
30011" becomes "10".

4.5 Error check
The error check of the communication frame uses CRC-16.
4.5.1 CRC generation
The communication method of the CRC system divides the information that should be sent with the
generation polynomial expression and add the remainder behind information.
The generation polynomial expression is as follows.
Calculate the data from the slave address to last data with the following procedure.
1. Load a 16 bit CRC register with FFFF hex.
2. Exclusive OR the first byte(8 bit) of the message with low-order byte of the 16 bit register CRC,
putting the result in the CRC register.
3. Shift the CRC register one bit to the right (toward the LSB), zero-filling the MSB. Extract and
examine the LSB.
4. (If LSB was 0): Repeat step 3 (another shift)
(If LSB was 1): Exclusive OR the CRC register with the polynomial value A001 hex (1010 0000
0000 0001)
5. Repeat step 3 and 4 until 8 shifts have been performed. When this is done, a complete data byte will
have been processed.
6. Repeat step 2 through 5 for the next byte of message. Continue doing this until all bytes have been
processed.
7. The final content of the CRC register is the CRC value.
8. When the CRC is placed into the message, its upper byte and lower byte must be swapped as
described below.
Placing the CRC into the Message:
When the 16bit CRC(two bytes) is transmitted the message, the low-order byte will be transmitted
first, followed by the high-order byte.
For example, if the CRC value is 1241 hex (0001 0010 0100 0001);

5.4.1 Reading of a digital setting value
[Function code: 01 (01H)]
Continuously digital setting value (ON/OFF) is read out only the designated number from the
designated No.
ON/OFF data is configured of the data of the answer message that was arranged to 1 data (1 byte)
in the order of 8 each numbers.
LSB (D0 side) of each data becomes the youngest number of the digital data.
In the case that the reading number is not 8 multiples, an unnecessary bit becomes 0.

“ON”.
