As a maintenance engineer dealing with a Siemens S7-1500 PLC that suddenly loses communication with multiple servo drives during production, what systematic troubleshooting approach would you take beyond just checking cables and connections?

Q: As a maintenance engineer dealing with a Siemens S7-1500 PLC that suddenly loses communication with multiple servo drives during production, what systematic troubleshooting approach would you take beyond just checking cables and connections?

Hey, I&#39;m dealing with a frustrating situation where our S7-1500 PLC suddenly lost communication with multiple servo drives right in the middle of a production run. I&#39;ve already checked the obvious stuff like cables and connections, but I need a more systematic approach to get to the root cause. What should I be looking at next to diagnose this properly?
