01
Problem
A hypothetical production machine needs more maintainable controls and clearer status information for operators.
02
Solution
Existing electrical drawings and operating sequences would inform the scope for PLC, operator panel and cabinet upgrades. Manual operation, alarm descriptions and setup screens can be designed together.
03
System architecture
Existing machine signals → new control cabinet → PLC → HMI. Retained mechanical components and replaced interfaces would be determined during an actual assessment.

05
Result
This is an example application scenario. No measured cycle time, quality improvement or completed Petra project results are claimed.
