IEC 62881:2018解决了C&E矩阵的设置和实施，以便在工程活动中一致使用。它旨在描述一种简单的格式，用于支持项目或维护活动中涉及的不同工程学科之间的一致信息交换。该文件定义了C&E矩阵内容的最低要求，该内容源自现有设计文件，例如P&ID或口头描述。将C&E矩阵中定义的关系转换为用于PLC/DCS应用编程的功能或源代码超出了本文档的范围。此外，本文档不涵盖在专用自动化平台上实现复杂和/或顺序逻辑，这将需要完成/遵循额外的规定。应当理解，C&E矩阵实际上可以用于记录工厂设备的故障反应，因此可以用作要应用的必要安全验证的参考点。本文档中定义的C&E矩阵不具有与鱼骨图或石川图相同的范围，鱼骨图或石川图在文献中通常被称为因果图。

IEC 62881:2018 addresses the setting and implementation of C&E matrices for a consistent use in engineering activities. It aims to describe a simple format used to support a consistent exchange of information between different engineering disciplines involved in project or maintenance activities. The document defines the minimum requirements of the C&E matrix content, which is derived from existing design documents, for example P&ID or verbal descriptions.
The transfer of the relations defined in C&E matrices into a functional or source code for the application programming of PLC/DCS is out of the scope of this document. In addition, this document does not cover the implementation of complex and/or sequential logics at a dedicated automation platform, which will require additional stipulations to be done/ followed.
It is understood, that C&E matrices in fact can be used to document the fault reactions of the plant equipment and therefore can be used as reference point for the necessary safety verifications to be applied.
C&E matrices as defined in this document do not have the same scope as Fishbone or Ishikawa diagrams, which are often named in the literature as cause and effect diagrams.
