Motion and state
Its rotary state can be driven from a PLC output so speed and direction remain visible during a scan.
PLC control pattern
Commission it by proving valve position before accepting valve command.
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 Valve command (%); PLC input Valve position (%)
| Signal | PLC direction | Type / range |
|---|---|---|
| Valve command command | output | float · % · 0–100 |
| Valve position position | input | float · % · 0–100 |
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
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.
