标准摘要
[中文适用范围]: 本文件适用于使用符合10BASE-T1L标准的物理层(PHY)(见IEEE Std 802.3-2022第146条)的工艺自动化设备。Ethernet-APL本质安全配置文件具有不同的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),简化了不同Ethernet-APL端口互连的检查。 本文件包含以下技术特点: • 具有主干/支线安装能力的拓扑结构; • 2线技术(全双工通信数据速率为10 Mbit/s); • 长距离(指电缆长度可达数百米,最长可达1000米); • 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。 [外文原描述]: IEC TS 63444:2023 is applicable to process automation equipment using a 10BASE-T1L compliant (see IEEE Std 802.3-2022, Clause 146) 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. The following technical features are part of this document: - topology with trunk/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.
