Industrial communication networks - Profiles - Part 2: Additional fieldbus profiles for real-time networks based on ISO/IEC 8802-3 (IEC 61784-2:2019)

This document specifies - performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements; - profiles and related network components based on ISO/IEC/IEEE 8802- 3, IEC 61158 series, and IEC 61784-1; - RTE solutions that are able to run in parallel with ISO/IEC/IEEE 8802-3 based applications. These communication profiles are called Real-Time Ethernet communication profiles.

EC 61784-2:2019 spécifie: • les indicateurs de performance prenant en charge les schémas de classement pour les exigences RTE (Real-Time Ethernet); • les profils et les composants de réseau connexes reposant sur l’ISO/IEC/IEEE 8802-3, la série IEC 61158 et l’IEC 61784-1; • les solutions RTE capables de fonctionner en parallèle avec les applications ISO/IEC/IEEE 8802-3. Ces profils de communication sont appelés Ethernet en temps réel (RTE). Cette quatrième édition annule et remplace la troisième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: • la mise à jour de la référence de l’ISO/IEC 8802-3 à l’ISO/IEC/IEEE 8802-3; • la mise à jour des références datées à la série IEC 61158, à l’IEC 61784 1, à la série IEC 61784-5 et à l’IEC 61918 dans tout le document; • la mise à jour des tableaux de sélection pour CPF 2, CPF 3, CPF 4, CPF 8 et CPF 17; – CPF3: mise à jour des exigences pour toutes les classes de conformité; – CPF3: mise à jour des exigences de temporisation pour les appareils d'entrée-sortie; – CPF3: affinage des classes d'application ajoutées; • l'ajout d’une nouvelle famille de profils de communication – CPF 20 à l’Article 21; • l'ajout d’une nouvelle famille de profils de communication – CPF 21 à l’Article 22. La présente version bilingue (2020-04) correspond à la version anglaise monolingue publiée en 2019-04.

Industrijska komunikacijska omrežja - Profili - 2. del: Dodatni profili procesnih vodil za omrežja, ki delujejo v realnem času po ISO/IEC 8802-3 (IEC 61784-2:2019)

Ta dokument določa: – kazalnike delovanja, ki podpirajo razvrstitvene sheme za zahteve RTE (Real-Time Ethernet); – profile in povezane omrežne komponente na osnovi standarda ISO/IEC/IEEE 8802- 3, skupine standardov IEC 61158 in standarda IEC 61784-1; – rešitve RTE, ki lahko delujejo vzporedno z aplikacijami, ki temeljijo na standardu ISO/IEC/IEEE 8802-3. Ti komunikacijski profili se imenujejo komunikacijski profili RTE (Real-Time Ethernet).
