Industrial networks - Profiles - Part 2-19: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 19

This document defines extensions of Communication Profile Family 19 (CPF 19) for Real-Time Ethernet (RTE). CPF 19 specifies a Real-Time Ethernet (RTE) communication profile (CP) and related network components based on the IEC 61158 series (Type 27), 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 from standards or International Standards established by other standards bodies or open standards processes. NOTE 2 The RTE communication profile uses ISO/IEC/IEEE 8802-3 communication networks and its related network components and may in some cases amend those standards to obtain RTE features. NOTE 3 Some CPs of CPF 19 are specified in IEC 61784-1-19.

Réseaux industriels – Profils – Partie 2-19: Profils de bus de terrain supplémentaires pour les réseaux en temps réel fondés sur l’ISO/IEC/IEEE 8802-3 - CPF 19

L’IEC 61784-2-19:2023 définit les extensions de la famille de profils de communication 19 (CPF 19) pour Ethernet en temps réel (RTE). La CPF 19 spécifie un profil de communication (CP) Ethernet en temps réel (RTE, Real-Time Ethernet) et des composants de réseau associés basés sur la série IEC 61158 (Type 27), l’ISO/IEC/IEEE 8802-3 et d’autres normes.

Industrijska omrežja - Profili - 2-19. del: Dodatni profili procesnih vodil v realnem času po ISO/IEC/IEEE 8802-3 - CPF 19 (IEC 61784-2-19:2023)

Ta dokument določa razširitve družine komunikacijskih profilov 19 (CPF 19) za Real-Time Ethernet (RTE). Družina komunikacijskih profilov 19 določa komunikacijski profil (CP) Real-Time Ethernet (RTE) in povezane omrežne komponente na osnovi skupine standardov IEC 61158 (tip 27), 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 profil RTE uporablja komunikacijska omrežja v skladu s standardom ISO/IEC 8802-3 maj in z njimi povezane omrežne komponente ter lahko v nekaterih primerih za pridobitev funkcij RTE te standarde spremeni.
OPOMBA 3: Nekateri komunikacijski profili iz družine komunikacijskih profilov 19 so določeni v standardu IEC 61784-1-19.
