IEC 61158-1:2019

Industrial communication networks - Fieldbus specifications - Part 1: Overview and guidance for the IEC 61158 and IEC 61784 series

IEC 61158-1:2019 specifies the generic concept of fieldbuses. This document presents an overview and guidance for the IEC 61158 series explaining the structure and content of the IEC 61158 series, relating the structure of the IEC 61158 series to the ISO/IEC 7498-1 OSI Basic Reference Model and showing how to use parts of the IEC 61158 series in combination with the IEC 61784 series. It also provides explanations of some aspects of the IEC 61158 series that are common to the type specific parts of the IEC 61158 5 including the application layer service description concepts and the generic fieldbus data types. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
• updates of the references to and information about the IEC 61158 series, IEC 61784 1, IEC 61784 3, IEC 61784-5 series and IEC 61918 throughout the document;
• new Type 25 and the related profile family CPF 20;
• new Type 26 and the related profile family CPF 21.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 1 : Vue d’ensemble et recommandations pour les séries IEC 61158 et IEC 61784

l’IEC 61158-1:2019 précise le concept générique de bus de terrain. Le présent document donne également une vue d’ensemble et des recommandations relatives à la série EC 61158 en:
• expliquant la structure et le contenu de la série IEC 61158;
• associant la structure de la série IEC 61158 à l’ISO/IEC 7498-1 Modèle de référence de base OSI;
• présentant la structure logique de la série IEC 61784;
• présentant la manière d’utiliser les parties de la série IEC 61158 en combinaison avec la série IEC 61784;
• donnant des explications relatives à certains aspects de la série IEC 61158 communs aux parties spécifiques au type de l’IEC 61158 5, y compris les concepts de description de la couche d’application de service et les types de données de bus de terrain génériques
Cette deuxième édition annule et remplace la première édition publiée en 2014. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
• mises à jour des références et des informations relatives à la série IEC 61158, à l’IEC 61784 1, à l’IEC 61784 3, à la série IEC 61784-5 et à l’IEC 61918 tout au long du document;
• nouveau Type 25 et la famille de profils CPF 20 associée;
• nouveau Type 26 et la famille de profils CPF 21 associée;
