Abstract

L'invention concerne un procédé et un système servant à reconnaître la configuration, c'est-à-dire les composants de ce système. Une unité de commande centrale (ZST) communique par l'intermédiaire d'un bus de communication (BUS) avec des modules de commande (STM1, STM2, STM3). Un signal d'identification (IS) est transmis d'un module à l'autre. Le module (STM) dans lequel est présent le signal d'identification (IS) émet ses propres données d'identification. L'unité de commande centrale (ZST) édite ensuite des adresses de configuration.
