DIN EN IEC 62657-4:2024-04

This part of IEC 62657 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 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 document is applicable to develop, implement, or modify procedures or solutions. This document is intended for manufacturers of industrial radio equipment, system integrators, and operators of radio systems. Equipment manufacturers should provide quantitative parameters for their radio equipment and systems based on IEC 62657-2 to improve the handling of coexistence of industrial radio applications. This document specifies the relevant parameters and interfaces for automatic coexistence management. System integrators should develop, implement, and manage industrial radio automation systems in cooperation with the plant owner and equipment manufacturers throughout the entire lifetime of the plant. This document provides essential parameters and interfaces for coexistence management for system integrators.
