Mira opened TwinCAT 3 and scrolled through her safety logic. It was clean. Too clean. Standard functions: two-hand controls, light curtains, e-stop monitoring. But the random trip persisted.
For every FB_Step , set a realistic tMaxTime . If a pneumatic cylinder takes 0.5 seconds normally, set the timeout to 1 second. If it exceeds that, the library will call the onTimeout method where you can trigger an alarm and abort the sequence. This turns intermittent mechanical issues into diagnosable faults. beckhoff sistema library

The result is modular, self-documenting code. If you need to insert a "Heat" step between Fill and Mix, you simply add a new step and adjust transitions. You don't risk breaking the CASE logic's index order. Mira opened TwinCAT 3 and scrolled through her safety logic
