Product safety requirements for PLC and the other types of industrial control equipment now in the scope of this standard are specified in IEC 61010-2-201, which replaces the requirements of Clauses 11 to 14 of IEC 61131-2:2007.
IEC 61131 is an IEC standard for programmable controllers. It was first published in 1993;[1] the current (third) edition dates from 2013.[2] It was known as IEC 1131 before the change in numbering system by IEC. The parts of the IEC 61131 standard are prepared and maintained by working group 7, programmable control systems, of subcommittee SC 65B of Technical Committee TC65 of the IEC.
IEC 61131-2:2017 specifies functional and electromagnetic compatibility requirements and related verification tests for 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.This fourth edition cancels and replaces the third edition published in 2007. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) removal of safety requirements and instead pointing to IEC 61010-2-201;b) addition of negative logic digital inputs and outputs;c) addition of Type 3-d digital input;d) addition of 2,7 GHz to 6 GHz requirement for Radio-frequency electro-magnetic amplitude modulated immunity;e) clarification of temperature testing;f) clarification of type testing;g) deprecation of certain technologies;h) general update of multiple aspects of functionality and EMC;i) reorganization of clauses to associate requirements and verifications more closely. 153554b96e
