- Starting point
- Packaging facility in Central Switzerland. Sporadic plant stoppages after 3–4 hours of production, the internal team and the plant builder have not isolated the cause.
- Task
- Structured on-site fault analysis, evaluation of diagnostic buffer, drive trace and sensor logic, written findings and recommendations for the in-house team.
- Solution
- Two-day on-site visit: code review of the relevant program parts, trace recording on the drive, analysis of sensor signals under load. Finding: thermal drift issue at a Profinet switch, solution proposal with concrete replacement plan.
- Outcome
- Cause identified, plant stable again after switch replacement. Written findings documentation for the internal team.
