标准范围

IEC 62424:2016规定了如何在P&ID中表示过程控制工程请求，以便在P&ID和PCE工具之间自动传输数据，并避免对PCE的图形P&ID符号的误解。它还定义了通过数据传输语言（称为CAEX）在过程控制工程工具和P&ID工具之间交换过程控制工程请求相关数据。这些规定适用于此类工具的出口/进口申请。这第二版取消并取代了2008年出版的第一版。本版构成技术修订版。它是第一版的兼容扩展。主要变化和扩展有:-更新的定义和新的定义；-标识替换为参考名称；-更新PCE类别和流程功能；-CAEX 3.0版，引入:原生多角色支持；-嵌套接口；-生命周期元信息；-单独的属性库；-更新的示例；-更新的PCE请求的电子数据模型:用于基本PCE请求属性的新规范属性库；-用于进一步PCE请求属性的新的信息扩展属性库；-PCE请求的新信息电子数据模型。

IEC 62424:2016 specifies how process control engineering requests are represented in a P&ID for automatic transferring data between P&ID and PCE tool and to avoid misinterpretation of graphical P&ID symbols for PCE. It also defines the exchange of process control engineering request relevant data between a process control engineering tool and a P&ID tool by means of a data transfer language (called CAEX). These provisions apply to the export/import applications of such tools. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. It is a compatible extension of the first edition. The main changes and extensions are:
- updated definitions and new definitions;
- identification replaced with reference designation;
- updated PCE categories and process functions;
- CAEX version 3.0, introduction of: native multiple role support;
- nested interfaces;
- life cycle meta information;
- a separate Attribute library;
- updated examples;
- updated electronic data model of the PCE request: new normative attribute library for basic PCE request attributes;
- new informative extended attribute library for further PCE request attributes;
- new informative electronic data model for the PCE request.
