Appendix B Response message data structure: Abnormality response message data structure: Note: How many bytes of data in response message depend on the read device address number in through reading device address number in DVP10MC11T. DVP10MC11T in request message. So n value in Byte n in response message can be calculated 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:
