Description of BS EN IEC 62657-4:2025 2025IEC 62657-4:2025 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, – CC sequences and message formats for data exchange. This document is not restricted to a specific radio frequency range nor is it restricted to a specific wireless communication technology. This edition includes the following significant technical changes with respect to the previous edition: a) The data item (parameter) to be exchanged between CCP and CMWCA and CMWD to ensure interoperability between CCP providers and device providers. b) The sequence of services conducted between CCP and CMWCA and CMWD are now defined. When the CCP providers and the device providers implement similar process, clearly defined sequence and unified execution specifications ensure interoperability as expected. c) The message formats of sequence diagram to be exchanged between CCP and CMWCA and CMWD are defined. By defining the message formats, the hierarchical structure of each data (parameter), and implementing the same message format by the CCP provider and the device provider, enables to exchange data correctly and ensure interoperability.
