A

Data structure of an exception response message:
Byte NO. Name Byte
Byte0 Modbus ID Single byte
Byte1 0x80+ Function code
Single byte
Byte2 Exception response code Single byte
Byte3
Low byte of CRC check sum
Low byte
Byte4
High byte of CRC check sum High byte
Note: The written value 0x0000 for the bit register in request message or response message
indicates the value FALSE is written in the bit register; the written value 0xFF00 for the bit
register indicates the value TRUE is written in the bit register.

Example
The value of %QX0.0 in DVP15MC11T is set to TRUE and the address of %QX0.0 is set to
0xA000 via function code 05.
Request message: 01 05 A0 00 FF 00 AE 3A
Response message: 01 05 A0 00 FF 00 AE 3A
