IEC 61131-10:20 19为IEC 61131-3项目的导出和导入指定了基于XML的交换格式。在IEC 61131-3环境中实现的完整IEC 61131-3项目可以在不同的编程环境之间传输。它允许交换配置元素、数据类型和POU: ？文本语言，指令列表(IL)， ？文本语言，结构化文本(ST)， ？图形语言梯形图（LD）， ？图形语言、功能框图(FBD)和 ？顺序功能图（SFC）。 交换格式被指定为相应的XML架构。XML模式是一个独立的文件，扩展名为.xsd，因此是本规范的一部分。该模式的规范包含在附录A中。附录B提供了扩展的推荐模式。附录C中给出了一个示例XML文档。假设本文档的读者熟悉XML技术。

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.
