This is a common issue that can be hard to diagnose, our customer was experiencing intermittent PLC stop issues that were hindering production. Unfortunately the HMI alarm page on Siemens 840D & 810D didn't give enough information to correctly diagnose route cause PLC stop issues.
Using S7 software and our Simatic Field PG, we were able to view the diagnostic buffer and identify a faulty output module. Once replaced, the issue is resolved.
