IEC 61158-6-12:2010

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

IEC 61158-6-12:2010 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). It defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-12:2010, and the externally visible behavior associated with their transfer. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes with respect to the previous edition are: bug fixes and editorial improvements.

Réseaux de communication industriels - Spécifications de bus de terrain - Partie 6-12: Spécification de protocoles de couche Application - Eléments de Type 12

La CEI 61158-6-12:2010 spécifie le protocole de la couche Application de bus de terrain de la CEI, en conformité avec le modèle de référence de base OSI (ISO/CEI 7498) et avec la structure de la couche Application OSI (ISO/CEI 9545). Elle vise à définir le protocole mis en place pour définir le comportement visible de l'extérieur associé à leur transfert. Cette deuxième édition annule et remplace la première édition parue en 2007. Elle constitue une révision technique. Les principales modifications sont: correction d'erreurs et améliorations rédactionnelles.
