Training course
Learning catalog for logic and PLC/FBD
Choose a track, read a lesson, open the related FBD diagram, and verify behavior in simulation.
How to use the course
- 1. Read the short article and review the signals.
- 2. Open the ready-made FBD diagram in the editor.
- 3. Toggle inputs and verify the result in simulation.
- 4. Change the diagram and check the new condition.
