IEC 61499-2:20 12定义了软件工具的要求，以支持IEC 61499-1中列举的以下系统工程任务: -功能块类型的说明； -资源类型和设备类型的功能规范； -分布式IPMCS的规范、分析和验证； -分布式IPMCS的配置、实现、操作和维护； -软件工具之间的信息交换。第二版取消并取代了2005年出版的第一版，构成了技术修订。本版相对于上一版包括以下重大技术变更:附录A的内容已更新，以符合IEC 61499-1第二版的技术变更。表A.4和A.5中算法的文本内容现在允许使用CDATA部分。

IEC 61499-2:2012 defines requirements for software tools to support the following systems engineering tasks enumerated in IEC 61499-1:
- the specification of function block types;
- the functional specification of resource types and device types;
- the specification, analysis, and validation of distributed IPMCSs;
- the configuration, implementation, operation, and maintenance of distributed IPMCSs;
- the exchange of information among software tools. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The contents of Annex A have been updated to conform to the technical changes of the second edition of IEC 61499-1. CDATA sections are now allowed for the textual contents of algorithms in Tables A.4 and A.5.
