Exercice 3 — Séquence automatisée (SFC + LD) But : séquencer une machine à 3 étapes (Alimentation, Traitement, Vidange). Capteurs : S_Alim OK (I1.0), S_Trait OK (I1.1), S_Vid OK (I1.2). Commandes sorties : Valve_Alim (Q1.0), Heater (Q1.1), Valve_Vid (Q1.2). Bouton cycleStart (I0.2), cycleStop (I0.3).
Once the 10th item is detected, the conveyor stops for to allow a new box to move into place, then restarts and resets the counter. The Solution (Counter Logic): Input S2 is connected to a CU (Count Up) block. Preset Value (PV) of the counter is set to 10 . When Counter.Done (Q) is reached: Trigger a Timer (T2) for 5 seconds. Deactivate Conveyor Output (M2) . When T2.Done is true: Reset the Counter. Restart Conveyor Output (M2) .
