Appendix A Data structure of response message: Data structure of abnormality response message: Note: How many bytes of data in request message are determined by the number of bit device where to write the value in the response message. Set DVP10MC11T M0~M7=1000 0001, M8~M15=0001 1000, M16~M19=0110 via function code 0F; M0 address: 0x0800 Request message: “01 0F 08 00 00 14 03 81 18 06 8B F9” Response message: “01 0F 08 00 00 14 57 A4” The Indication of Modbus Communication Port LED COM1 LED is RS-232 communication port indicator used by PLC module to show RS-232 communication state.
COM2 LED is RS-485 communication port indicator commonly used by motion control module and PLC module to show RS-485 communication state.
