Watch ladder logic execute in real time on a Mini PLC — see contacts and coils change state live as the program solves, right in the software.
⚡ QUICK ANSWER
When a PLC runs, it solves its ladder logic in a repeating scan — reading inputs, evaluating each rung, and updating outputs, over and over, many times a second. Monitoring the program online lets you watch that happen live: contacts and coils highlight as they go true, so you can see power flow through the rungs in real time. This is one of the best ways to understand how ladder logic actually behaves and to troubleshoot — if an output isn't turning on, you can trace the rung and see exactly which contact is blocking it. Here it's shown on the P1-M622-16DR Mini PLC. The full wiring and testing walkthrough is in the guide below.

📚 WHAT YOU'LL LEARN
✅ What it looks like to watch ladder logic execute live
✅ How contacts and coils highlight as they change state
✅ How the PLC scan solves the rungs over and over in real time
✅ How live monitoring helps you troubleshoot a rung fast
❓ FREQUENTLY ASKED
Q: What does it mean to watch ladder logic in real time?
A: When you monitor a running PLC online, contacts and coils highlight as they go true, so you can watch power flow through each rung live as the program solves. The full walkthrough is in the guide.
Q: How does live monitoring help troubleshooting?
A: If an output won't turn on, you can trace its rung and see exactly which contact is false and blocking it — far faster than guessing.
