EN IEC 62026-1:2019

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

IEC 62026-1:2019 is available as IEC 62026-1:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62026-1:2019 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. 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.

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

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
