Chapter 9 Serial port RS485 communication protocol
9.1 Communication overview
Our series of inverters provide users with a common industrial control RS485 communication
interface, in which The MODBUS standard protocol is used for communication. The inverters
can be used as slave connected to the host (such as PLC controller, PC), both of which have
the same communication interface and protocol, for the purpose of centralized monitoring of
the inverters. Or one inverter can be used as host and other inverters as slaves, all
connected with RS485 communication interface, to achieve multi-machine interaction of the
inverters. And with this communication interface, a Keyboard can also be connected to
inverters for remote operation.
The MODBUS communication protocol of the inverter supports two transmitting ways: RTU
mode and ASCII, and either can be choose. The following is a detailed description of the
communication protocol of the inverter.
