Defines safety requirements and related verification tests for control equipment of the following types: - Programmable controllers (PLC and PAC); - the components of Distributed Control Systems (DCS); - the components of remote I/O - systems; - industrial PC (computers) and Programming and Debugging Tools (PADTs); - Human-Machine Interfaces (HMI); - any product performing the function of control equipment 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 and continuous control.

IEC 61010-2-201:2013 specifies the complete safety requirements for control equipment (e.g. programmable controller (PLC)), the components of Distributed Control Systems, I/O devices, Human Machine Interface (HMI)). Safety terms of general use are defined in IEC 61010-1. More specific terms are defined in each part. This part incorporates the safety related requirements of Programmable Controllers. Annex DD provides a cross reference between clauses of this standard and those of IEC 61010-1 or IEC 61131-2:2007. It has the status of a basic safety publication in accordance with IEC Guide 104.

This publication is to be read in conjunction with IEC 61010-1:2010.
