IEC 61158-5-12:2019

Industrial communication networks - Fieldbus specifications - Part 5-12: Application layer service definition - Type 12 elements

IEC 61158-5-12:2019 defines the services provided to the FAL user at the boundary between the user and the application layer of the fieldbus reference model, and Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model. This standard 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 application layer structure (ISO/IEC 9545). This fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
•Technical corrections; and
•Editorial improvements for clarification

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 5-12: Définition des services de la couche liaison de données - Eléments de type 12

L’IEC 61158-5-12:2019 fournit des éléments communs pour les communications de messagerie prioritaires et non prioritaires élémentaires entre les programmes d’application des environnements d’automatisation et le matériel spécifique au bus de terrain de type 12. On utilise le terme "prioritaire" pour traduire la présence d’une fenêtre temporelle, à l’intérieur de laquelle il est exigé qu’une ou plusieurs actions spécifiées soient réalisées selon un certain niveau de certitude. Si les actions spécifiées ne sont pas réalisées dans la fenêtre temporelle, les applications demandant les actions risquent de connaître une défaillance, avec les risques que cela comporte pour les équipements, les installations et éventuellement la vie humaine.
