Motion and state
Its process animation communicates running, stopped and abnormal machine state.
PLC control pattern
Commission it by proving damper position, measured airflow before accepting damper command.
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 Damper command (%); PLC input Damper position (%); PLC input Measured airflow (m³/h)
| Signal | PLC direction | Type / range |
|---|---|---|
| Damper command position_command | output | float · % · 0–100 |
| Damper position position_feedback | input | float · % · 0–100 |
| Measured airflow airflow | input | float · m³/h · 0–5000 |
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.
