Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 1: General rules (IEC 62026-1:2019)

This part of IEC 62026 applies to interfaces between low-voltage switchgear, controlgear, and
controllers (e.g. programmable controllers, personal computers, etc.).
This document does not apply to higher level industrial communication networks that have
become known as fieldbuses and are considered by IEC subcommittee 65C.
The purpose of this document is to harmonize and define rules, components and requirements
of a general nature applicable to industrial CDIs. Those features of the various CDI standards
which can be considered as general have therefore been brought together in this document.
For each CDI, two main documents are necessary to determine all requirements and tests:
a) this document, referred to as “IEC 62026-1” in the relevant CDI parts covering the various
types of CDIs;
b) the specific CDI part of the IEC 62026 series.
A specific CDI part may omit a general requirement if it is not applicable, or it may add to it if
it is inadequate in the particular case.
NOTE Product-specific requirements for products incorporating a CDI are given in the relevant product standards.
These requirements apply in addition to those given in this document.

Appareillage à basse tension - Interfaces appareil de commande-appareil (CDI) - Partie 1: Règles générales (IEC 62026-1:2019)

IEC 62026-1:2019 est disponible sous forme de IEC 62026-1:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62026-1:2019 s’applique aux interfaces entre l’appareillage à basse tension et des appareils de commande (par exemple automates programmables, ordinateurs personnels, etc.). Le présent document ne s’applique pas aux réseaux de communication industriels de plus haut niveau connus sous le nom de bus de terrain et qui relèvent du sous-comité 65C de l’IEC. Cette troisième édition annule et remplace la deuxième édition parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) exigences supplémentaires pour les informations et les instructions relatives à la sécurité, notamment les mesures à prendre, s’il y a lieu, pour parvenir à la conformité CEM; b) alignement des exigences CEM concernant l’immunité sur celles de la série de normes IEC 61000-6. Niveau d’essai des champs électromagnétiques rayonnés aux fréquences radioélectriques porté à 6 GHz; c) alignement des exigences CEM concernant les émissions sur celles de la publication CISPR 11 actuelle.

Nizkonapetostne stikalne in krmilne naprave - Vmesniki krmilnikov (CDIs) - 1. del: Splošna pravila (IEC 62026-1:2019)

Ta del standarda IEC 62026 se uporablja za vmesnike med nizkonapetostnimi stikalnimi in krmilnimi napravami ter krmilniki (npr. programirljive krmilnike, osebne računalnike itd.).
Ta dokument se ne uporablja za visokonivojska industrijska komunikacijska omrežja, ki so bila poimenovana »vodila« in jih obravnava pododbor IEC 65C.
Namen tega dokumenta je uskladiti in določiti pravila, komponente ter splošne zahteve, ki se uporabljajo za industrijske vmesnike krmilnikov. Te značilnosti različnih standardov za vmesnike krmilnikov, ki jih je mogoče obravnavati kot splošne, so tako združene v tem dokumentu.
Za vsak vmesnik krmilnika sta potrebna dva glavna dokumenta, ki določata vse zahteve in preskuse:
a) ta dokument, imenovan »IEC 62026-1« v zadevnih delih o vmesnikih krmilnikov, ki zajemajo različne vrste vmesnikov krmilnikov;
b) poseben del o vmesnikih krmilnikov iz skupine standardov IEC 62026.
Poseben del o vmesnikih krmilnikov lahko izpušča splošno zahtevo, če se ne uporablja, ali pa jo dopolnjuje, če je neustrezna v določenem primeru.
OPOMBA: Posebne zahteve za izdelke, ki vključujejo vmesnik krmilnika, so podane v ustreznih standardih za izdelek.
Te zahteve se uporabljajo poleg zahtev, podanih v tem dokumentu.

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

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62026-1 has been prepared by subcommittee 121A: Low-voltage

switchgear and controlgear, of IEC technical committee 121: Switchgear and controlgear and

their assemblies for low voltage.

This third edition cancels and replaces the second edition published in 2007. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) additional requirements for safety information and instructions, including the measures to

be taken, if any, for achieving EMC compliance;

b) EMC immunity requirements aligned with current IEC 61000-6 series of standards.

Radiated radio-frequency electromagnetic fields test level increased to 6 GHz;
c) EMC emissions requirements aligned with current CISPR 11 publication.
