IEC 62026-1:2007

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

This International Standard applies to interfaces between low-voltage switchgear, controlgear, and controllers (e.g. programmable controllers, personal computers, etc.). This standard 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 standard 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 part of IEC 62026.

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

La présente Norme internationale s'applique aux interfaces entre l'appareillage à basse tension et des appareils de commande (par exemple automates programmables, ordinateurs personnels, etc.). La présente norme ne s'applique pas aux réseaux de communication industriels de plus haut niveau connus sous le nom de bus de terrain et développés par le sous-comité 65C de la CEI. La présente norme vise à harmoniser et définir les règles, les composants et les exigences de nature générale applicables aux CDI industriels. Les caractéristiques générales des normes des différents CDI ont donc été rassemblées dans la présente partie de la CEI 62026.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 17B: Low-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
This second edition of IEC 62026-1 cancels and replaces the first edition published in 2000.
It represents some general updating without technical changes with regard to the previous
edition.
The text of this standard is based on the following documents:
CDV Report on voting
17B/1505/CDV 17B/1544/RVC
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the IEC 62026, under the general title Low-voltage switchgear and

controlgear – Controller-device interfaces (CDIs), can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until the

maintenance result date indicated on the IEC web site under “http://webstore.iec.ch” in the data

related to the specific publication. At this date, the publication will be

• reconfirmed;

INTRODUCTION
The class of controller-device interfaces (CDIs) covered in this International Standard includes

industrial CDIs for control systems, factory automation and process automation.

Industrial CDIs have proliferated to meet specific user needs, but no single CDI meets all

needs. The reason for multiple solutions is the wide range of physical, usage, information

content and configuration requirements. The physical requirements have resulted in CDIs with

widely differing
