CLC/TC 65X/WG 04 - Harmonization of standards under EMCD and LVD

In addition to the requirements of IEC 61326-1, this part of IEC 61326 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.

This part of IEC 61131 specifies functional and electromagnetic compatibility requirements and related verification tests for industrial control equipment of the following types: - programmable controllers (PLC); - programmable automation controller (PAC); - remote I/O; - programming and debugging tools (PADTs); - industrial PC (computers) and industrial panel PC; - displays and human-machine Interfaces (HMI) for industrial use; - distributed control system (DCS), and DCS components that are listed here in the scope; - any product where the primary purpose is performing the function of industrial control equipment, including PLC and/or PAC, and/or their associated peripherals which have as their intended use the control and command of machines, automated manufacturing and industrial processes, e.g. discrete, batch and continuous control. In this document "control equipment" is equivalent to "industrial control equipment" as are PLC and PAC.
