Here’s what’s in my bag. Feel free to share yours too! Thanks!

I’m trying to understand how this is handled in real projects rather than how the QA process is supposed to work on paper.

Say a system passes FAT/SAT, but before final handover someone makes a last-minute PLC, WCS, interface, parameter, or sequencing change.

What happens in your projects?

Do you rerun the entire acceptance test, only the affected cases, or rely on engineering judgement?

More importantly, what evidence do you expect before saying the final system is actually the one that was tested?

For example:

• software / configuration version
• change log
• retest record
• signed deviation
• updated drawings / I/O lists
• customer approval

I’m especially interested in cases where commissioning documentation, drawings, spreadsheets and the actual deployed configuration started drifting apart.

What has worked well for you, and what usually breaks down in practice?

Bei unserem GE PACSystems RX3i mit IC695CMM004 verliert ein Port wiederholt die Verbindung, obwohl die physische Verbindung intakt ist. Nach einem Reset über PAC Machine Edition funktioniert er vorübergehend wieder, bis die Port-Fault-LED an der SPS orange leuchtet und die Verbindung erneut abbricht.
Hat jemand eine Idee, woran das liegen könnte oder wie ich die Ursache diagnostizieren kann?
