标准摘要
[中文适用范围]： IEC 61326-2-7:2025 规定了适用于至少使用一个符合 IEC TS 63444 的以太网 APL（以太网高级物理层）端口的工业过程自动化设备的电磁兼容性（EMC）测试要求。本文件涵盖的设备类型包括基础设施设备（如交换机）以及测量和控制设备。本文件为用于过程控制和过程测量设备的 APL 接口的 EMC 测试设置提供了相关要求。设备的其他功能由 IEC 61326 系列的其他部分进行覆盖。注：以太网-APL 使用 IEEE 标准 802.3 2022 以太网物理层 10BASE-T1L，适用于通过单根平衡导线对进行全双工通信。测试等级依据产品规格或用户文档中所说明的预期环境，并从 IEC 61326-1 中适当选择。 [外文原描述]： IEC 61326-2-7:2025 specifies the EMC test requirements for process automation equipment using at least one Ethernet APL (Ethernet ADVANCED PHYSICAL LAYER) compliant port according IEC TS 63444. The type of equipment covered by this document includes INFRASTRUCTURE DEVICES such as switches as well as measurement and control devices. This document provides requirements for the EMC test setups of the APL interface for devices intended for use in process control and process measurement. The other functions of the equipment remain covered by other parts of the IEC 61326 series. NOTE Ethernet-APL uses IEEE Std. 802.3 2022 Ethernet Physical Layer 10BASE-T1L, suitable to be used for full-duplex communication over a single balanced pair of conductors. The test levels are based on the intended environment as stated in the product’s specification or user documentation and selected appropriately from IEC 61326-1.
