Abstract

L'invention concerne un outil d'ingénierie à contrôleur logique programmable (2) comprenant : une unité de communication (204) destinée à rechercher un contrôleur logique programmable dans un système de contrôleur logique programmable et à acquérir, de la part du contrôleur logique programmable trouvé lors de la recherche, des informations représentant un réseau affilié; une unité de commande d'affichage (201) destinée à générer, en se basant sur les informations acquises par l'unité de communication (204), un diagramme de configuration de système présentant la configuration de réseau du système de contrôleur logique programmable; et une unité de stockage de données (203) destinée à générer des informations de liste pour les contrôleurs logiques programmables inclus dans le diagramme de configuration de système et stockant les informations de liste et les informations acquises par l'unité de communication (204). L'unité de commande d'affichage (201) génère, au moment où le diagramme de configuration de système est mis à jour, un diagramme de configuration de système affichant la différence avec le diagramme de configuration de système généré précédemment en se basant sur les informations de liste et les informations acquises par l'unité de communication (204) et stockées par l'unité de stockage de données (203).
