I faced a similar problem related to CP5622. PLC-SCADA (S7-300 - WinCC RT) communication was working fine. After 3 days of installation at site , the PLC-SCADA communication lost. We connected the separate earthing to PC, we tested by another Profibus and MPI cable but it does not work. We removed CP card from PCI slot and installed it again, after that MPI communication started working but Profibus does not worked on the same hardware. So I placed all tags from Profibus to MPI protocol in WinCC. But after 15 days again same issue observed and communication lost. This time I tested by installing the CP card to all the PCI slot (x4, x16) available on the PC motherboard but till now PLC-SCADA communication not placed. (PG/PC interface, MPI properties, MPI parameters in tag management all are ok.) The green LED on CP card is flashing continuously. I will be thankful if anyone had faced the same problem and got the solution. ------------------------------------------------------------------------------------------ |
