Test a PLC stop button at every stage and troubleshoot ladder logic with the ACC Simulator's Step mode — toggle inputs and see which contacts pass.
⚡ QUICK ANSWER
To verify a PLC stop button, press Stop during forward travel, reverse travel, and at each sensor position — the motor output should drop out immediately every time. If a step misbehaves, switch the ACC Simulator to Step mode, manually toggle each input, press Step, and watch which contacts pass power to pinpoint the failing rung.

📚 WHAT YOU'LL LEARN
✅ Test the stop button at every stage — forward travel, reverse travel, and each sensor
✅ Confirm the motor output drops out immediately on Stop
✅ Use the ACC Simulator's Step mode to debug ladder logic
✅ Toggle inputs manually and step through to see which contacts pass
❓ FREQUENTLY ASKED
Q: How do I properly test a PLC stop function?
A: Press Stop in every operating state — forward, reverse, and at each sensor — and confirm the output drops out immediately each time, not just from a standstill.
Q: My rung isn't behaving — how do I find the problem?
A: Use Step mode in the simulator: toggle inputs manually and step through so you can see exactly which contacts are passing power and which rung is breaking.
