Serial Connection with Codesys OPC Server
Hello i am trying to connect my PLC PM554 eco through serial rs232 (tk503 cable) to Codesys OPC server but it is not possible. When i test it with ethernet it works. What do i do wrong?
i changed the comunication parameters in Codesys OPC configurator to match the ones in the codesys that let me connect to plc. While i can connect to PLC normally i cant connect to OPC with the same parameters (serial rs 232). How is that possible? Does the codesys OPC supports serial communication?
