I hope you can help me.
My company colleague is facing a situation with Rockwell PLC and Cimplicity software (HMI).
A couple of days ago we found out that the HMI had a problem to save the correct day and year. Due that we were facing problems with the Cimplicity license. The problem was solve just changing the CMOS battery. But now after restore the HMI, we could not establish de communication between PLC and the HMI. We already check a ton of options and so far without success.
I would kindly ask you any of you ever faced this kind of situation? Please give a hand up about what you think. I really appreciate that.
