Automatisation et technique des commandes - SCE

7.EXEMPLE D’APPLICATION

Nous allons dans notre premier programme STEP 7 résoudre une tâche simple.

Une presse avec cage de protection ne doit être déclenchée avec le bouton-poussoir de démarrage S1 que si la cage de protection est fermée. Cet état est surveillé par un capteur de cage de protection BO. Si c’est le cas, une soupape 5/2 Y0 pour le cylindre de presse est activée pendant exactement 10 secondes pour le moulage sous pression de la forme.

Pour des raisons de sécurité, la presse doit remonter lorsque le bouton-poussoir S1 est relâché ou que le capteur cage de protection B0 ne réagit pas.
