IEC 61918:2018
(Main)Industrial communication networks - Installation of communication networks in industrial premises
Industrial communication networks - Installation of communication networks in industrial premises
IEC 61918:2018 specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC 61784-5 series.
This fourth edition cancels and replaces the third edition published in 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the reference to ISO/IEC 24702 has been replaced with reference to the new ISO/IEC 11801-3; this affects Table 2;
b) some terms and abbreviated terms have been modified in Clause 3;
c) Subclauses 4.1.2, 4.4.2.5, 4.4.3.4.1 and 5.7 have been updated;
d) Figure 2 and Figure 3 have been updated; Figure 13, Figure 16, Figure 30 and Figure 49 have been added;
e) Table 7 has been updated;
f) Annex D and Annex M have been extended to cover additional communication profile families; Annex H has been extended to cover the M12-8 X-coding connector use;
g) Annex O has been modified by including references to the new edition of the
ISO/IEC 11801 series, ISO/IEC TR 11801-9902 and ISO/IEC 14763-4;
h) Annex P has been added.
This standard is to be used in conjunction with the IEC 61784-5 series with regard to the installation of communication profiles (CPs).
Réseaux de communication industriels - Installation de réseaux de communication dans des locaux industriels
IEC 61918:2018 spécifie les exigences de base pour l’installation d'un support de réseaux de communication à l'intérieur et entre des îlots d'automatisation de sites industriels. Le présent document couvre le câblage symétrique et à fibres optiques. Elle couvre également l’infrastructure de câblage des supports sans fil, mais pas le support sans fil lui-même. D’autres supports sont couverts par l'IEC 61784-5 (toutes les parties).
Cette quatrième édition annule et remplace la troisième édition publiée en 2013. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) la référence à l'ISO/IEC 24702 a été remplacée par la référence à la nouvelle ISO/IEC 11801-3, ce qui a un impact sur le Tableau 2;
b) certains termes et abréviations ont été modifiés à l'Article 3;
c) les Paragraphes 4.1.2, 4.4.2.5, 4.4.3.4.1 et 5.7 ont été mis à jour;
d) la Figure 2 et la Figure 3 ont été mises à jour. La Figure 13, la Figure 16, la Figure 30 et la Figure 49 ont été ajoutées;
e) le Tableau 7 a été mis à jour;
f) l'Annexe D et l'Annexe M ont été développées afin de couvrir des familles de profils de communication supplémentaires. L'Annexe H a été développée pour couvrir l'utilisation du connecteur M12-8 codage X;
g) l'Annexe O a été modifiée en intégrant des références à la nouvelle édition de la série ISO/IEC 11801, à l'ISO/IEC TR 11801-9902 et à l'ISO/IEC 14763-4;
h) l'Annexe P a été ajoutée.
La présente norme doit être utilisée conjointement avec la série IEC 61784-5 en ce qui concerne l’installation des profils de communication (CP).
