Abstract

L'invention concerne un système (Sys) et un procédé permettant l'élimination automatique d'une tension perturbatrice excessive dans un bus d'alimentation (EB) par lequel des unités fonctionnelles décentralisées (E) agencées dans une installation industrielle sont alimentées en électricité. Selon le procédé, a) un système de commande maître (STW) échange des informations sur un bus de données (CB, NB1, NB2) avec les unités fonctionnelles décentralisées (E) au moyen de datagrammes ; b) des unités de nœud de réseau (SND) sont agencées séquentiellement entre deux points d'alimentation (PS1, PS2) d'un bus d'alimentation (EB) de conception annulaire et permettent aux unités fonctionnelles décentralisées (E) d'accéder au bus énergétique (EB) et optionnellement au bus de données (CB, NB1, NB2) ; c) les unités de nœud de réseau (SND) sont munies d'un module de commutation commandable (S) qui comprend un premier commutateur (S1) et un second commutateur (S2), les deux commutateurs (S1, S2) permettant de commuter respectivement un accès aux deux points d'alimentation (PS1, PS2) ; d) un module d'évaluation (CPU, SL) mesure la tension perturbatrice et la compare à une valeur limite et/ou contrôle le bus d'alimentation (EB) afin de détecter la présence éventuelle d'un défaut à la terre d'un conducteur du bus d'alimentation (EB), un des deux commutateurs (S2) d'une unité de réseau (SND4) pouvant être ouvert en présence d'une valeur inférieure à la valeur limite de la tension perturbatrice et/ou en présence d'un défaut à la terre.
