IEC 62264-6:2020

Enterprise-control system integration - Part 6: Messaging service model

IEC 62264-6:2020 defines a technology independent model for a set of abstract services that is located above the application layer of the OSI model, and that is used for exchanging transaction messages based on the transaction models defined in IEC 62264-5. The model, which is called the Messaging Service Model (MSM), is intended for interoperability between manufacturing operations domain applications and applications in other domains.

Intégration des systèmes entreprise-contrôle - Partie 6: Modèle de service de messagerie

IEC 62264-6:2020 définit un modèle, indépendant de la technologie employée, pour un ensemble de services abstraits qui est situé au-dessus de la couche d'applications du modèle OSI et qui est utilisé pour échanger des messages de transaction sur la base des modèles de transaction définis dans l'IEC 62264-5. Le modèle, appelé Modèle de Service de Messagerie (MSM), est conçu pour l'interopérabilité entre les applications du domaine des opérations de fabrication et les applications d'autres domaines.
