En ce qui concerne l'équipement de communication, il existe des solutions qui permettent de concevoir ledit équipement sous forme d'unité interchangeable conformément aux différentes normes de communication. Cet équipement peut être réalisé sous forme de module enfichable autonome à installer à l'intérieur de l'appareil, sous forme de module à enficher de l'extérieur dans ledit appareil ou sous forme de module enfichable sur une interface d'appareil dirigée vers l'extérieur. La chaîne fonctionnelle : fonction d'appareil - API - communication - système principal est commune à toutes les solutions de la technique actuelle. A cet effet, l'API est complètement intégré dans l'appareil aussi bien du point de vue du matériel que de celui des structures fonctionnelles et de données internes, ce qui nécessite en règle générale des composants matériels et logiciels spécifiques ainsi qu'une série de composants coûteux spécialement conçus pour la communication. L'objectif de cette invention est de concevoir un appareil doté d'une structure de commande et de communication flexible ainsi qu'un procédé correspondant, qui permettent l'interchangeabilité de pièces de l'appareil. A cet effet, l'appareil selon l'invention, qui est connecté à d'autres appareils ou à un dispositif de commande principal d'un système d'automatisation par l'intermédiaire d'un bus de données série (FES), est constitué d'au moins deux ou de plusieurs interfaces de communication (KS) et d'au moins un automate programmable industriel (API), de sorte que cet automate programmable industriel (API) est conçu sous forme d'unité interchangeable et les données sont transmises entre les interfaces de communication (KS) en étant traitées par l'intermédiaire dudit automate programmable industriel interne (API) et/ou de manière entièrement transparente. Cette invention s'applique en particulier au domaine de l'automatisation.
