Step-by-Step Diagnosis:

1. Upload the Ladder: Read the PMC file from the control to the software.
2. Set to "Monitor Mode": You cannot edit live on most older PMCs without stopping the machine. Use F5 (Monitor) to watch contact states change in real-time.
3. Cross-Reference: Right-click (or Ctrl+E) on a coil to see where its contacts are used. This is the fastest way to find why an interlock is active.
4. Watch Window: Add specific addresses (e.g., G8.4) to a watch list to see their value updating without scrolling through 5,000 rungs.
