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 LIEC 61158-5-25:2019 definit de maniere abstraite le service visible de lexterieur fourni par les differents types de la couche application de bus de terrain en termes a) de modele abstrait visant a la definition des ressources dapplication (objets) qui peuvent etre manipulees par des utilisateurs utilisant un service FAL; b) devenements et dactions liees aux primitives du service; c) de parametres associes a chaque evenement et action de primitive, ainsi que de forme prise par ces parametres; et d) dinteraction entre ces evenements et ces actions, ainsi que de sequences valides desdits evenements et actions.
