工业网络 以太网-APL端口配置文件/以太网-SPE配置文件规范

[中文适用范围]： 本文件适用于使用符合10BASE-T1L（见IEEE Std 802.3-2022第146条）物理层（PHY）的过程自动化设备。具有不同预定义实体或限制参数（例如电压、电流、功率、电容、电感、电缆长度）的以太网APL本质安全配置简化了不同以太网APL端口互连的检查。此外，本文件也适用于使用符合10BASE-T1L和Power over Data Lines（PoDL）物理层（PHY）的工厂和楼宇自动化及控制设备，用于非本质安全以太网安装。注：在本文件中，术语“以太网SPE”用于PoDL兼容的PHY。本文件包括以下技术特性：– 主干/支线安装能力拓扑；– 2线技术（10 Mbit/s全双工通信数据速率）；– 长距离（指数百米电缆长度，跨度可达1000 m）；– 本质安全（在危险区域安装支持以太网的现场设备）；– 通过用于数据通信的同一2线电缆为现场设备供电；– 工厂和楼宇自动化中的非本质安全以太网安装。 [外文原描述]： IEC TS 63444:2026 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 63444:2026 is applicable to process automation equipment using a 10BASE-T1L compliant Physical Layer (PHY). Ethernet-APL intrinsically safe profiles with different predefined entity or limitation parameters (for example voltage, current, power, capacitance, inductance, cable length) simplify the examination of the interconnection of different Ethernet-APL ports. Furthermore, this document is also applicable to factory and building automation and control equipment using a 10BASE-T1L compliant, and Power over Data Lines (PoDL) compliant Physical Layer (PHY) for non-intrinsically safe Ethernet installations. NOTE In this document the term Ethernet-SPE is used for PoDL compliant PHY. The following technical features are part of this document: - topology with trunk and spur installation capability; - 2-wire technology (full-duplex communication data rate of 10 Mbit/s); - long distance (refers to cable lengths of several hundred meters, with spans up to 1 000 m); - intrinsic safety (installation of Ethernet-capable field devices in hazardous areas); - power supply to field devices over the same 2-wire cable used for data communication; - non-intrinsically safe Ethernet installation in factory and building automation. This second edition cancels and replaces the first edition published in 2023. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new power class for Ethernet-APL; b) addition of Ethernet-SPE; c) clarification of usability of Ethernet-APL in non-hazardous locations.
