DVP-MC operating manual B-5
Data order Name Byte
Byte9 High byte
Byte10
Device address content in DVP10MC11T
Low byte
… High byte
Byte n
Device address content in DVP10MC11T
Low byte
Abnormality response message data structure:
Data order Name Byte
Byte0 High byte
Byte1
Transaction identifier
Low byte
Byte2 High byte
Byte3
Protocol identifier
Low byte
Byte4 High byte
Byte5
Modbus data length
Low byte
Byte6 Modbus ID Single byte
Byte7 0x80+ function code Single byte
Byte8 Abnormality response code Single byte
Note: How many bytes of data in response message depend on the read device address number in
DVP10MC11T in request message. So n value in Byte n in response message can be calculated through
reading device address number in DVP10MC11T.
¾ Example: To read the content of 0x1000 and 0x1001 address in DVP10MC11T
0x1000 and 0x1001 are the Modbus address of D0 and D1 in DVP10MC11T respectively. Suppose D0
value is 0x0100 and D1 is 0x0200.
Request message: “ 00 00 00 00 00 06 01 03 10 00 00 02”
Response message: “00 00 00 00 00 07 01 03 04 01 00 02 00”
