IEC 61158-6-12:2014

Industrial communication networks - Fieldbus specifications - Part 6-12: Application layer protocol specification - Type 12 elements

IEC 61158-6-12:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-12, and define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 12 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 third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are:
- bug fixes;
- editorial improvements;
- support of Explicit Device Identification added in ESM.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 6-12: Spécification du protocole de la couche application - Eléments de type 12

L'IEC 61158-6-12:2014 décrit le protocole mis en place pour définir la représentation filaire des primitives de service définies dans la CEI 61158-5-12 et définir le comportement visible de l'extérieur associé à leur transfert. La présente norme spécifie le protocole de la couche application de bus de terrain de Type 12, en conformité avec le modèle de référence de base OSI (ISO/CEI 7498-1) et la structure de la couche application OSI (ISO/CEI 9545). Cette troisième édition annule et remplace la deuxième édition parue en 2010. Elle constitue une révision technique. Les principales modifications sont:
- réparations des erreurs;
- améliorations éditoriales;
- prise en charge de l'Identification Explicite d'Appareils ajoutée en ESM.
