ac800m(pm856) and cp554(hmi) communication through rs485
In the controller ac800m(pm856) i used com3 port(rs232c) ,In cp554 i want to use rs485 port. I am using a RS232 to RS485 converter.Could you tell me the communication settings in CP554 and how to enable the RS485 port.
In CP554, RS485 is a separate port (4-pin jack connection block). Under Peripheral configuration you can find RS485 port settings. Define the controller protocol under this RS485 port to enable communication with the controller.
