Industrial networks - Profiles - Part 2-12: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 12

IEC 61784-2-12:2023 defines Communication Profile Family 12 (CPF 12). CPF 12 specifies a set of Real-Time Ethernet (RTE) communication profiles (CPs) and related network components based on the IEC 61158 series (Type 12), 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. NOTE 1 All CPs are based on standards or draft standards or International Standards published by the IEC or on standards or International Standards established by other standards bodies or open standards processes. NOTE 2 The RTE communication profiles use ISO/IEC/IEEE 8802-3 communication networks and its related network components and in some cases amend those standards to obtain RTE features.

Réseaux industriels – Profils – Partie 2-12: Profils de bus de terrain supplémentaires pour les réseaux en temps réel fondés sur l’ISO/IEC/IEEE 8802-3 – CPF 12

L’IEC 61784-2-12:2023 définit la famille de profils de communication 12 (CPF 12). La CPF 12 spécifie un ensemble de profils de communication (CP) Ethernet en temps réel (RTE, Real-Time Ethernet) et de composants de réseau associés basés sur la série IEC 61158 (type 12), 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. NOTE 1 Tous les CP sont fondés sur des normes ou projets de normes, ou des Normes internationales, publiés par l’IEC, ou bien sur des normes ou des Normes internationales établies par d’autres organismes de normalisation ou des processus de normalisation ouverts. NOTE 2 Les profils de communication RTE utilisent les réseaux de communication ISO/IEC/IEEE 8802-3 et leurs composants de réseau connexes et amendent dans certains cas ces normes, pour obtenir les fonctions RTE.

Industrijska omrežja - Profili - 2-12. del: Dodatni profili procesnih vodil v realnem času po ISO/IEC/IEEE 8802-3 - CPF 12 (IEC 61784-2-12:2023)

Standard IEC 61784-2-12:2023 določa družino komunikacijskih profilov 12 (CPF 12). Družina komunikacijskih profilov 12 določa sklop komunikacijskih profilov (CP) Real-Time Ethernet (RTE) in povezanih omrežnih komponent na osnovi skupine standardov IEC 61158 (tip 12), standarda ISO/IEC/IEEE 8802-3 in drugih standardov.
Za vsak komunikacijski profil RTE ta dokument določa tudi povezane kazalnike uspešnosti RTE in odvisnosti med temi kazalniki uspešnosti RTE.
OPOMBA 1: Vsi komunikacijski profili temeljijo na standardih ali osnutkih standardov ali mednarodnih standardih, ki jih je objavila komisija IEC, oziroma na standardih ali mednarodnih standardih, ki so jih določili drugi organi za standarde ali procesi odprtih standardov.
OPOMBA 2: Komunikacijski profili RTE uporabljajo komunikacijska omrežja v skladu s standardom ISO/IEC 8802-3 in z njimi povezane omrežne komponente ter v nekaterih primerih za pridobitev funkcij RTE te standarde spremenijo.
