My CPU is going into stop mode and SF mode. The first time it happened I was able to do a warm restart but went back into stop mode 10 minutes later. The CPU was changed but would not go into run mode. The CPU was powered down overnight and restarted in the morning but after another warm restart it faulted after 2 hours. It was decided to remove the PLC and check connections and dust build up. One input and one output module was also changed. I have attached the diagnostic buffer file. Events 18 to 26 were before I reset the PLC clock, so event 26 was 6:30 AM 04/16/2024 Would appreciate any help with this. AttachmentDiagnose.txt (116 Downloads) |

To keep you all updated. The fault has now been resolved and the CPU has stayed in run for the last 30 hours. The second input and output modules were changed for the ones that were removed previously. Although not sure which module was at fault ( input or output ), I am happy the problem seems to be resolved. I have added the diagnostic file from the now happy CPU.
