IEC 61158-5-25:2019

Industrial communication networks - Fieldbus specifications - Part 5-25: Application layer service definition - Type 25 elements

IEC 61158-5-25:2019 specifies the structure and services of the IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI ApplicationLayer Structure (ISO/IEC 9545).FAL services and protocols are provided by FAL application-entities (AE) contained within the application processes. The FAL AE is composed of a set of object-oriented Application Service Elements (ASEs) and a Layer Management Entity (LME) that manages the AE. The ASEs provide communication services that operate on a set of related application process object (APO) classes. One of the FAL ASEs is a management ASE that provides a common set of services for the management of the instances of FAL classes

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 5-25: Définition des services de la couche application - Eléments de type 25

L'IEC 61158-5-25:2019 définit de manière abstraite le service visible de l'extérieur fourni par les différents types de la couche application de bus de terrain en termes
a) de modèle abstrait visant à la définition des ressources d'application (objets) qui peuvent être manipulées par des utilisateurs utilisant un service FAL;
b) d'événements et d'actions liées aux primitives du service;
c) de paramètres associés à chaque événement et action de primitive, ainsi que de forme prise par ces paramètres; et
d) d'interaction entre ces événements et ces actions, ainsi que de séquences valides desdits événements et actions.
