Abstract

La présente invention concerne un procédé de configuration automatique de relations de surveillance entre des appareils d'automatisation (5, 6) qui sont reliés entre eux d'une manière communicative dans un système d'automatisation (5, 6, 7) distribué. Un premier appareil d'automatisation (6) envoie une demande de surveillance (M1), un second appareil d'automatisation (5) envoie une offre de surveillance (M2) et un coordinateur de surveillance (7) vérifie à l'aide des informations reçues si le second appareil d'automatisation (5) est apte à exécuter la surveillance demandée par le premier appareil d'automatisation (6). En cas de détermination de l'aptitude, la relation de surveillance (M5) est configurée automatiquement par le coordinateur de surveillance (7) dans le système d'automatisation (5, 6, 7). Cela rend possible une surveillance mutuelle d'appareils d'automatisation (5, 6) sans nécessiter des dépenses de projet supplémentaires dans ce but. Cela produit un effet avantageux sur la fiabilité d'une installation automatisée (1).
