Motion and state
Its opening state provides visible access and interlock feedback.
PLC control pattern
Commission it by proving guard closed before accepting guard unlock.
Fault practice
Inject jammed, slow states and require the PLC sequence to detect, stop and recover deliberately.
Signal map
I/O you can reason about
PLC output Guard unlock; PLC input Guard closed
| Signal | PLC direction | Type / range |
|---|---|---|
| Guard unlock unlock | output | bool |
| Guard closed closed | input | bool |
Fault and recovery exercise
Make abnormal states part of the sequence
Inject jammed, slow 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.
Free first success

Open a related browser scenario, run the PLC logic and see the component state respond. Start without installing software or entering a card.
