Delta Electronics DVP10MC11T [315/375] Appendix b
Appendix B
B-8 DVP-MC operating manual
Response message data structure:
Data order Name Byte
Byte0
Transaction identifier
High byte
Byte1 Low byte
Byte2
Protocol identifier
High byte
Byte3 Low byte
Byte4
Modbus data length
High byte
Byte5 Low byte
Byte6 Modbus ID Single byte
Byte7 Function code Single byte
Byte8
The start address of word devices where to write values in
DVP10MC11T
High byte
Byte9 Low byte
Byte10
The address number of word devices where to write values.
（Counted by Words）
High byte
Byte11 Low byte
Abnormality response message data structure:
Data order Name Byte
Byte0
Transaction identifier
High byte
Byte1 Low byte
Byte2
Protocol identifier
High byte
Byte3 Low byte
Byte4
Modbus data length
High byte
Byte5 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.
Example: To write 0x0100 and 0x0200 to 0x1000 and 0x1001 address via function code 06.
0x1000 and 0x1001 are the Modbus address of D0 and D1 in DVP10MC11T respectively.
Request message: “ 00 00 00 00 00 0B 01 10 10 00 00 02 04 01 00 02 00”
Response message: “00 00 00 00 00 06 01 10 10 00 00 02”
