Industrial communication networks - Profiles - Part 2: Additional fieldbus profiles for real-time networks based on ISO/IEC/IEEE 8802-3
IEC 61784-2:2019 specifies the performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements; the profiles and related network components based on ISO/IEC 8802-3 or IEEE 802.3, IEC 61158 series, and IEC 61784-1 and the RTE solutions that are able to run in parallel with ISO/IEC 8802-3 or IEEE 802.3 based applications. These communication profiles are called Real-Time Ethernet communication profiles. This fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. The main changes are:
• update of reference from ISO/IEC 8802-3 to ISO/IEC/IEEE 8802-3;
• update of the dated references to the IEC 61158 series, to IEC 61784 1, to the IEC 61784-5 series and to IEC 61918 throughout the document;
• update of selection tables for CPF 2, CPF 3, CPF 4, CPF 8 and CPF 17;
• CPF3: update of the requirements for all conformance classes;
• CPF3: updated timing requirements for IO devices;
• CPF3: refining the added application classes;
• addition of a new Communication Profile Family – CPF 20 in Clause 21;
• addition of a new Communication Profile Family – CPF 21 in Clause 22

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.
