IEC 61784-2-3:2023

Industrial networks - Profiles - Part 2-3: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 3

IEC 61784-2-3:2023 defines extensions of Communication Profile Family 3 (CPF 3) for Real-Time Ethernet (RTE). CPF 3 specifies a set of Real-Time Ethernet (RTE) communication profiles (CPs) and related network components based on the IEC 61158 series (Type 10), ISO/IEC/IEEE 8802-3 and other standards.
For each RTE communication profile, this document also specifies the relevant RTE performance indicators and the dependencies between these RTE performance indicators.

Réseaux industriels – Profils – Partie 2-3: Profils de bus de terrain supplémentaires pour les réseaux en temps réel fondés sur l’ISO/IEC/IEEE 8802-3 <em>– </em>CPF 3

L’IEC 61784-2-3:2023 définit les extensions de la famille de profils de communication 3 (CPF 3) pour l’Ethernet en temps réel (RTE). La CPF 3 spécifie un jeu de profils de communication (CP) Ethernet en temps réel (RTE) et les composants de réseau connexes basés sur la série IEC 61158 (type 10), l’ISO/IEC/IEEE 8802-3 et d’autres normes.
Pour chaque profil de communication RTE, le présent document spécifie également les indicateurs de performance RTE correspondants et les dépendances entre ces indicateurs de performance RTE.
