Motion and state
Its visible state changes with simulated I/O, making status and diagnosis readable in the scene.
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
The model teaches PLC sequence behaviour and diagnosis. Confirm ratings, wiring, guarding, process calculations and commissioning limits against the real manufacturer documentation and site design.
