Hello guys, you would have some example of RS-485 communication with the 750-653 card that you could show me so that I can continue the application is for an ABB Nexus II voltage meter. If my PLC had a serial input it would be easier as I configure the modbus TCP map .... But as the PLC 750-880 doesn’t have to do the nodbus map by hand ... if you have an example for me to follow I will be grateful ... thanks already.
