Abstract

L'invention concerne un procédé de reconfiguration d'un dispositif d'automatisation. Selon ce procédé, des données de configuration d'une nouvelle configuration logicielle peuvent être évaluées sans que le dispositif d'automatisation passe en mode ARRET. Ainsi, il n'est pas necéssaire que les modules périphériques centralisés et/ou décentralisés passent en mode commandé, ce qui signifie que la commande en boucle ouverte peut immédiatement reprendre après la reconfiguration.
