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.

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.
Industrijska omrežja - Profili - 2-3. del: Dodatni profili procesnih vodil v realnem času po ISO/IEC 8802-3 - CPF 3 (IEC 61784-2-3:2023)
Ta del standarda IEC 61784-2 določa razširitve družine komunikacijskih profilov 3 (CPF 3) za Real-Time Ethernet (RTE). Družina komunikacijskih profilov 3 določa sklop komunikacijskih profilov (CP) Real-Time Ethernet (RTE) in povezanih omrežnih komponent na osnovi skupine standardov IEC 61158 (tip 10), 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.
OPOMBA 3: Nekateri komunikacijski profili iz družine komunikacijskih profilov 3 so določeni v standardu IEC 61784-1-3.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretatio
