Ladder Logic Simulator

Experiment with a simulated Start/Stop motor circuit. Toggle the inputs, run the scan, and watch the ladder path and output status update in real time. This is a learning demo, not a controller for real machinery.

Ready. Turn on the Stop circuit OK input, then press Start to latch the motor output.

How it works

1. When Start is pressed and the stop circuit is healthy, the motor output turns on.

2. The holding contact keeps the output on after Start is released.

3. When the stop circuit opens, the logic path breaks and the output turns off.
