Dear all I have a PLC s7-400 with a CPcard and some I/O cards beside it , On the CP i see INTF LED is red and Stop LED is yellow , and also on the CPU module i see EXTF LED is red, but the cpu is still run .What is the problem ? In the text of CP443-1 diagnostic buffer , I see one error related to synchronizing the internal clock , What is this related to ??! Also i attached a file that you can see the status of LEDs and the text related to diagnostic buffer of CPU and CP443-1 , maybe it can help to find the problem. Very Thanks AttachmentDiagnostc texts & pictures.zip (46 Downloads) |
