标准摘要
[中文适用范围]： 本部分IEC 61139规定了无线单点数字通信接口（SDCI无线）。这是对IEC 61131-9中规定的单点数字通信接口（SDCI）技术的扩展。 本文件规定了W-Masters和W-Devices的无线通信服务和协议（根据ISO/OSI参考模型的物理层、数据链路层和应用层）。 注：本文件不涵盖与更高级别系统（如现场总线）的集成。 [外文原描述]： IEC 61139-3:2023 specifies a wireless single-drop digital communication interface (SDCI wireless). This is an extension to the single-drop digital communication interface (SDCI) technology that is specified in IEC 61131-9. This document specifies the wireless communication services and protocol (physical layer, data link layer and application layer in accordance with the ISO/OSI reference model) for W‑Masters and W‑Devices. NOTE This document does not cover the integration into higher level systems such as fieldbuses.
