3) Communication function
The controller supports RS485 (COM0) and CAN communication function, and may meet different
communication needs of customers. Matched resistors are provided for CAN communication and
COM0 RS485 communication and can be enabled or disenabled with the dial switch. 8pin dial switch
as shown below is applied. And the dial switch is OFF by default.

◆
RS485 communication function
For the controller and inverter, communication COM1 with the controller is achieved through internal
connector.
◆
COM1 communication interface
COM1 is same as that of general version PLC. For details on usage, please refer to COM1 of general
version PLC.
◆
CAN communication function
Controller CAN communication supports free protocol conforming to CAN2.0 protocol specification.
CAN communication baud rate: fixed to be 250 kbps.
The schematic diagram of CAN networking is as follows:
Support CANTX and CANRX free protocol command, J1939 communication protocol is implemented
by user program, and CANLink protocol is not supported. The special components for CAN
communication include:
