DIN EN 14908-9:2025-02

This document enables utilization of wireless communication in the general title Control Network Protocol (CNP) in the EN 14908 series. The wireless communication can provide fast and easy system deployment, robust, de-centralized and autonomous network operation for EN 14908 based applications. In addition, this document defines the requirements for the radio communication applicable for CNP layer operation. This document specifies an adaptation layer for the control network protocol (CNP), as described in EN 14908-1 to utilize wireless communication network. This document defines the services of the wireless communication provided to CNP layer for delivering data and commands towards and from sensors, actuators, etc. which are wirelessly connected as part of the EN 14908-1 network. For the radio communication different frequency bands can be utilized. Annex A defines requirement for operation in different frequency bands.
