Appendix B Response message data structure: Abnormality response message data structure: Note: The written value 0x0000 for bit device in request message or response message indicates be value written in device is 0; the written value 0xFF00 for bit device indicates the value written in device is 1. Example: Set the value of M0 in DVP10MC11T as 1 via function code 05; the address of M0 is 0x0800. Request message: “ 00 00 00 00 00 06 01 05 08 00 FF 00” Response message:
