Extension of RS485 Communication
Extended 485 communication does not support the DLT-645 protocol and only supports the Modbus-RTU protocol.
8.2.1
Extending RS485 Communication as a Modbus Slave Station
When the second communication serves as a slave station, as the first channel RS485 communication, only supports the 0x03
command and does not support the 0x10 command. Refer to Chapter 8 for the address table.
8.2.2 Modbus_TCP communication (Using ModScan software)
When using the Ethernet Modbus_TCP protocol, it supports 0x01 (read coil status), 0x02 (read input status), 03 (read hold register),
0x05 (write single coil). (Note: When using the 01, 02, and 05 commands, they all correspond to the APM8xx meter's own information.
DI1 and DO1 correspond to the starting address 0.)
