Programmable controllers - Part 5 : communications

Le présent document spécifie les aspects communication des automates programmables. Il spécifie du point de vue automate programmable comment un dispositif peut communiquer avec un automate programmable serveur et comment un automate programmable peut communiquer avec un dispositif. Il spécifie en particulier le comportement de l'automate programmable en tant que fournisseur de services pour d'autres dispositifs et les services que le programme d'application de l'automate programmable peut demander à d'autres dispositifs. Ce document n'a pas pour objet de spécifier comment un dispositif peut communiquer avec un dispositif utilisant un automate programmable routeur ou portail d'accès. Le comportement de l'automate programmable en tant que client et serveur de communication est spécifié indépendamment du sous-système de communication particulier, mais la fonctionnalité communication peut dépendre des performances du sous-système de communication utilisé.
