标准摘要
[中文适用范围]: 本规范描述了如何在 PI 图中表示过程控制工程请求。它还定义了过程控制工程工具和PI工具之间通过数据传输语言(称为CAEX)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/进口应用。 PI 图中 PCE 功能的表示由最少数量的规则定义,以清楚地指示其类别和处理功能@,独立于实现技术(参见第 6 条)。过程设备图形符号的定义(例如容器@阀门@柱子@等)@其实施和编号系统规则不属于本标准的范围。这些规则独立于本标准,可以在 DIN EN ISO 10628 或 ISO 14617 中找到@例如@。第 7 条指定不同工具和数据模型 CAEX 之间的数据流。 [外文原描述]: IEC 62424:2008 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. It cancels and replaces IEC/PAS 62424 published in 2005. This first edition constitutes a technical revision.
