工业自动化中的无线共存管理

[中文适用范围]： IEC 62657-2:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有变化。IEC 62657-2:2025 规定： – 无线通信共存的基本假设、概念、参数和程序； – 规定共存参数及其在需要无线共存的应用中的使用方式； – 为工业自动化工厂中的无线通信可用性和性能提供指南、要求和最佳实践；它涵盖了无线通信共存的生命周期； – 帮助所有参与相关职责的人员应对工业自动化工厂中无线通信共存管理生命周期每个阶段的关键方面。生命周期方面包括：规划、设计、安装、实施、操作、维护、管理和培训； – 为工业自动化站点的无线通信共存提供共同的参考点，作为帮助用户评估和衡量其工厂工作的同质指南； – 处理无线通信共存的操作方面，包括静态人/工具组织和动态网络自组织。 该文件通过支持使用共存管理来满足要求，为国家和地区法规做出了重大贡献。 此版本与上一版相比包括以下重大技术变化：a) 调整共存参数的一些定义和规范，以方便将来将其纳入 IEC 维护的 IEC 通用数据字典 (IEC CDD)；b) 调整一些定义和规范以与新的 IEC 62657-3 和 IEC 62657-4 保持一致；c) 本文件第 3 版于 2022 年 6 月发布。在本文件的最后开发阶段提出了一些意见，要求解释 IEC 62657 系列各部分的结构以及它们之间的关系。这些评论的解决被推迟到下一版，也就是这个版本。 [外文原描述]： IEC 62657-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
