IEC 62657-2:2022 this part:
• 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;

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. It does not exempt devices from conforming to all requirements of national and regional regulations.

IEC 62657-4:2022 specifies a concept and methods for central coordination (CC) of automation applications using wireless communications to extend the coexistence management according to IEC 62657-2. It establishes system elements, interfaces and relationships for a central coordination. Functions, data, and data exchange for assessing and maintaining the coexistence state are specified.
This document specifies the central coordination point (CCP) approach as one example of the usage of the formal description given in IEC 62657-3.
This document is applicable to develop, implement, or modify procedures or solutions.
This document provides requirements for automated coexistence management systems.
This document provides requirements for:
• determination of the coexistence state,
• automated coexistence management procedures,
• CC amendments for existing wireless communication solutions,
• CC functions that coordinate legacy and new wireless communication systems.
This document is not restricted to a specific radio frequency range nor is it restricted to a specific wireless communication technology.

This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision.
This second edition includes the following significant technical changes with respect to the previous edition:
a) update of the normative references, terms, definitions, symbols and abbreviations;
b) addition of terms;
c) checking of the life-cycle terms of this document versus the terms used in IEC 62890: and addition of explanations;
d) addition and modification of text to make the text more readable;
e) 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.

IEC 62657-1:2017 provides the wireless communication requirements dictated by the applications of wireless communication systems in industrial automation, and requirements of related context. The requirements are specified in a way that is independent of the wireless technology employed. The requirements are described in detail and in such a way as to be understood by a large audience, including readers who are not familiar with the industry applications.
This first edition cancels and replaces the first edition of IEC TS 62657-1 published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TS 62657‑1:2014:
a) update of requirements for wireless industrial applications;

IEC TS 62657-1:2014(en) provides the wireless communication requirements dictated by the applications of wireless communication systems in industrial automation, and requirements of related context. The requirements are specified in a way that is independent of the wireless technology employed. The requirements are described in detail and in such a way as to be understood by a large audience, including readers who are not familiar with the industry applications. Social aspects, environmental aspects, health aspects and market requirements for wireless communication systems in industrial automation are described to justify the wireless communication requirements. This Technical Specification describes requirements of the industrial automation applications that can be used to ask for additional dedicated, worldwide unique spectrum. This additional spectrum is intended to be used for additional wireless applications while continuing using the current ISM bands.
