IEC 62657-2:2017, – 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 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.<\/p>\n
