DIN EN IEC 61918:2025-05

This document provides a general reference for the installation of media for the most commonly used industrial communication networks in industrial premises. This document consists of uniform installation guidelines for industrial automation islands that contain control applications. In addition, it provides support on the definition and installation of interfaces between automation island networks and application-neutral cabling. This document specifies basic requirements for the installation of media for communication networks within and between the automation islands, of industrial sites. This document 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 IEC 61784-5 (all parts). This document is a companion standard to the communication networks of the industrial automation islands and especially to the communication networks specified in IEC 61158 (all parts) and IEC 61784 (all parts). This document does not take the implementation of power transmission using or via Ethernet cabling systems into consideration. The standard differs from DIN EN IEC 61918 (VDE 0800-500):2023-03 and DIN EN IEC 61918/A12 (VDE 0800-500/A12):2023-09 as follows: a) subclauses 4.1.2, 4.1.3, 4.2.1.2, 4.2.2, 4.2.3.2, 4.3.2.1, 4.3.2.3, 4.4.1.2.1, 4.4.2.2, 4.4.2.5, 4.4.3.1, 4.4.3.2.1, 4.4.3.4.1, 4.4.7.1.4, 4.4.7.3.1, 5.1.1, 5.7, 6.1, 6.2.8.3, 6.3.2.1.2, and 8.3.3 have been updated; b) Annex O has been amended by replacing the references to ISO/IEC TR 11801-9902 with references to ISO/IEC 11801-3:2017/AMD1:2021; c) Table B.3 has been updated; d) Clause B.6 has been added; e) Annexes D, I, J, K, and M have been updated; f) Annex Q has been added; g) the document has been editorially revised. This document is intended for use by planners, installers, testers, acceptance testing personnel, system administrators, and maintenance personnel of communication network installations in industrial premises, as it describes, among other things, the respective responsibilities.
