BS EN IEC 61158-5-25:2019

This standard BS EN IEC 61158-5-25:2019 Industrial communication networks. Fieldbus specifications is classified in these ICS categories:

• 25.040.40 Industrial process measurement and control
• 35.110 Networking
• 35.100.70 Application layer

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
