Industrial networks - Profiles - Part 2-18: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 18 (IEC 61784-2-18:2023)

This part of IEC 61784-2 defines Communication Profile Family 18 (CPF 18). CPF 18 specifies
a set of Real-Time Ethernet (RTE) communication profiles (CPs) and related network
components based on the IEC 61158 series (Type 22), 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 profile(s) use ISO/IEC/IEEE 8802-3 communication networks and its related
network components or IEC 61588 and in some cases amend those standards to obtain RTE features.

Industrijska omrežja - Profili - 2-18. del: Dodatni profili procesnih vodil v realnem času po ISO/IEC/IEEE 8802-3 - CPF 18 (IEC 61784-2-18:2023)

Ta del standarda IEC 61784-2 določa družino komunikacijskih profilov 18 (CPF 18). Družina komunikacijskih profilov 18 določa sklop komunikacijskih profilov (CP) Real-Time Ethernet (RTE) in povezanih omrežnih komponent na osnovi skupine standardov IEC 61158 (tip 22), 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 ali IEC 61588 ter v nekaterih primerih za pridobitev funkcij RTE te standarde spremenijo.

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
