Industrial networks - Coexistence of wireless systems - Part 2: Coexistence management
IEC 62657-2:2025 specifies: – the fundamental assumptions, concepts, parameters, and procedures for wireless communication coexistence; – specifies coexistence parameters and how they are used in an application requiring wireless coexistence; – provides guidelines, requirements, and best practices for wireless communication's availability and performance in an industrial automation plant; it covers the life‑cycle of wireless communication coexistence; – helps the work of all persons involved with the relevant responsibilities to cope with the critical aspects at each phase of life-cycle of the wireless communication coexistence management in an industrial automation plant. Life-cycle aspects include: planning, design, installation, implementation, operation, maintenance, administration and training; – provides a common point of reference for wireless communication coexistence for industrial automation sites as a homogeneous guideline to help the users assess and gauge their plant efforts; – deals with the operational aspects of wireless communication coexistence regarding both the static human/tool-organization and the dynamic network self-organization. This document provides a major contribution to national and regional regulations by supporting to fulfil the requirements using coexistence management. This edition includes the following significant technical changes with respect to the previous edition: a) alignment of some definitions and specifications of coexistence parameters in order to facilitate their future inclusion in the IEC Common Data Dictionary (IEC CDD) maintained by the IEC; b) alignment of some definitions and specifications to be consistent with the new IEC 62657-3 and IEC 62657-4; c) edition 3 of this document was published in June 2022. Some comments were made in the last development stages of this document asking for explanations on how the parts of the IEC 62657 series were structured and how they were related to each other. Resolution of these comments was deferred until a next edition, which means this edition.
Industrielle Kommunikationsnetze - Koexistenz von Funksystemen - Teil 2: Koexistenzmanagement
Réseaux industriels - Coexistence des systèmes sans fil - Partie 2: Gestion de coexistence
L'IEC 62657-2:2025 spécifie: – les hypothèses, concepts, paramètres et procédures de base qui permettent la coexistence de communications sans fil; – spécifie les paramètres de coexistence et comment ils sont utilisés dans une application qui exige une coexistence sans fil; – fournit les lignes directrices, exigences et meilleures pratiques en matière de disponibilité et de performance des communications sans fil dans une installation d'automatisation industrielle. Elle couvre le cycle de vie de la coexistence de communications sans fil; – facilite la tâche des personnes appelées à faire face aux aspects fondamentaux à chaque phase du cycle de vie de la gestion de coexistence de communications sans fil dans une installation d'automatisation industrielle. Les aspects du cycle de vie incluent: la planification, la conception, l'installation, la mise en œuvre, le fonctionnement, la maintenance, l'administration et la formation; – fournit une référence commune sur la coexistence de communications sans fil pour des sites d'automatisation industrielle sous la forme de ligne directrice homogène aidant les utilisateurs à évaluer et mesurer les efforts de leur installation; – traite des aspects fonctionnels de la coexistence de communications sans fil concernant tant l'organisation statique homme-outil que l'autoorganisation dynamique du réseau. Le présent document apporte une contribution majeure aux règlements nationaux et régionaux en fournissant un appui pour respecter les exigences en utilisant la gestion de coexistence. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) certaines définitions et spécifications des paramètres de coexistence ont été alignées afin de faciliter ultérieurement leur ajout dans le dictionnaire de données communes de l'IEC (CDD de l'IEC) géré par l'IEC; b) certaines définitions et spécifications ont été alignées pour des raisons de cohérence sur les nouvelles IEC 62657-3 et IEC 62657-4; c) l'édition 3 du présent document a été publiée en juin 2022. Des commentaires ont été formulés au cours des dernières étapes d'élaboration du présent document pour demander des explications concernant la structure des parties de la série IEC 62657 et les liens qui existent entre elles. Le traitement de ces commentaires a été reporté jusqu'à une prochaine édition, autrement dit la présente édition.
