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 for engineers to correctly diagnose the route cause PLC stop issues. This is a common complaint that can be hard to diagnose without the right equipment.
Using S7 software and our Simatic Field PG, we were able to view the diagnostic buffer and identify a faulty output module. Once we replaced the module, the issue was resolved.
