Motion and state
Its state is used to practise permissive and trip reasoning; it is not a safety-rated engineering model.
PLC control pattern
Commission it by proving active feedback before accepting enable.
Fault practice
Inject stuck-on, stuck-off states and require the PLC sequence to detect, stop and recover deliberately.
Signal map
I/O you can reason about
PLC output Enable; PLC input Active feedback
| Signal | PLC direction | Type / range |
|---|---|---|
| Enable enable | output | bool |
| Active feedback active | input | bool |
Fault and recovery exercise
Make abnormal states part of the sequence
Inject stuck-on, stuck-off states and require the PLC sequence to detect, stop and recover deliberately.

Engineering boundary
Training model only. It does not perform a machinery risk assessment, calculate performance level or SIL, replace a safety PLC, or validate a real safety function.
