Abstract

L'invention concerne un procédé pour mettre en exploitation (VIBS) une installation technique comprenant un dispositif comportant un système CAO (CAO) permettant d'établir et de représenter un dessin CAO comprenant des objets de dessin CAO (R) pour des ressources techniques de l'installation (ANL). Le dispositif comprend une plate-forme de données (DB) comprenant une bibliothèque pour les données de ressources techniques (BD), dans laquelle les attributs des objets d'instrumentation appartenant au type de ressources techniques sont inscrits, et un dispositif de commande (PLC), qui exécute un programme de commande pour l'installation technique (ANL). Selon l'invention, un type de ressources est ajouté à un objet de dessin (R) sélectionné à partir de la bibliothèque pour les données de ressources (BD). Enfin, des objets de déplacement (RF1, RF2, RT, RS1, RS2) CAO sont formés pour chaque objet d'instrumentation du type de ressources en fonction de ses attributs, et disposés, en vue d'être affichés dans un objet de dessin (R) CAO du dessin CAO correspondant. Selon l'invention, on peut quasiment commander un dessin CAO par l'intermédiaire de la commande PLC. De manière avantageuse, les ressources techniques et l'installation technique ne sont pas nécessairement existantes. De plus, un dessin CAO animé peut être utilisé dans tous les états d'une installation sélectionnée, grâce à l'utilisation du procédé de l'invention, ce qui permet de faire fonctionner virtuellement l'installation.
