SCAN CYCLE

Valcourt, 2:10 a.m. Nothing runs.

The factory's old controls engineer retired tonight and took every program along. You are the new hire. Your boss, Mireille, forgives nothing when an emergency stop is wired wrong.

Program real machines, the way automation engineers do.

• Ladder logic first: contacts, coils, seal-in circuits, set/reset, edges, timers, counters.
• Then Grafcet (IEC 60848 style sequential function charts): steps, transitions, timed conditions.
• Every machine is alive: animated in real time, scan cycle by scan cycle. Press the buttons, trigger a truck, a rainstorm, a jammed part, and see what your program does.

Then the test bench tries to break it. Each level ships with a spec sheet and a bench that replays every scenario: faults injected, sensors that lie, emergency stops pressed mid-cycle. When something fails, the bench shows you when and why.

Free demo: 10 stations, playable right here. The full game has 40 stations over four night shifts.

English and French. Mouse and keyboard.
