IEC 62424 Ed. 2.0 b:2016

Representation of process control engineering - Requests in P&I diagrams and data exchange between P&ID tools and PCE-CAE tools

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.
