Connect C200-Hg to HMI Hi Everyone This is my fist time using this site. I am a third year student at Humber College. I am doing my final project. I am trying to connect my PC and HMI through Ethernet and HMI to PLC through RS 232. The problem i am geting is that when i do all the connection my HMI shows "connecting" on the scrren nothing else. I also stop communicating with my PLC with Serial cable. I dont why i stop communicating with PLC. If anyone can help me what would be the problem. Why i stop communicating with PLC even though its in serial. PLC - Omron 200-HG CPU 43 Hmi - NS8-TV01B-V1) Thankyou
