ÍST EN 61131-2:2007

IEC 61131-10:2019 specifies an XML-based exchange format for the export and import of IEC 61131-3 projects. A complete IEC 61131-3 project implemented in an IEC 61131-3 environment can be transferred between different programming environments. It allows for the exchange of configuration elements, data types, and POUs written in:• the textual language, instruction list (IL),• the textual language, structured text (ST),• the graphical language, ladder diagram (LD),• the graphical language, function block diagram (FBD), and• sequential function chart (SFC).The exchange format is specified as a corresponding XML schema. The XML schema is an independent file with the .xsd extension and as such part of this specification. The specification of this schema is contained in Annex A. Annex B provides recommended schemata for extensions. An example XML document is given in Annex C. It is assumed that the reader of this document is familiar with XML technology.

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
