Advanced: Debugging the Logic in Real-Time​

To identify errors or analyze specific logic conditions while the simulation is running, use the Online Monitoring mode:

  1. In the EasyPLC Editor, click the Connect On-Line with PLC toolbar icon.
  2. In the project tree (left panel), navigate to:
    Software -> Program -> Main -> Main_Sequence_1.
  3. The editor will display the logic with live status updates:
    • Red Color: Indicates contacts or coils that are currently ON / TRUE.
    • Blue Color: Indicates contacts or coils that are currently OFF / FALSE.
