Industrial communication networks - Fieldbus specifications - Part 5-26: Application layer service definition - Type 26 elements
IEC 61158-5-26:2019 specifies the structure and services of the IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (see ISO/IEC 7498-1) and the OSI Application Layer Structure (see 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 5-26: Définition des services de la couche application - Éléments de type 26
L'IEC 6158-5-25:2019 définit de manière abstraite le service, visible par un observateur extérieur, assuré 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.
