Stack light

The stack light is a reusable 3D controls component for control panels and operator stations. In this simulator it coordinates commands, status and interlocks.

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 feedback before accepting green lamp, amber lamp, red lamp.

Fault practice

Inject stuck-on, stuck-off states and require the PLC sequence to detect, stop and recover deliberately.

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.
