FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62424 has been prepared by IEC technical committee 65:
Industrial-process measurement, control and automation.
This standard cancels and replaces IEC/PAS 62424 published in 2005. This first edition
constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
65/420/FDIS 65/428/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
Efficient process engineering requires highly sophisticated tools for the different needs of the
involved work processes and departments. These engineering tools are normally specialized
in Process Design (PD), in Process Control Engineering (PCE), etc. Therefore a working
interoperability is essential to optimize the engineering process in total. Thus, the definition of
a harmonized interface and data management is a core task to ensure a smooth workflow
during the whole project and to guarantee data consistency in the different tools.
This standard defines procedures and specifications for the exchange of PCE relevant data
provided by the Piping and Instrumentation Diagram (P&ID) tool. The basic requirements for a
change management procedure are described. A generally accepted technology for machine
information exchange, the Extensible Markup Language (XML) is used. Hereby, a common
basis is given for information integration.
However, a definition for uniform semantics is still necessary. CAEX (Computer Aided
Engineering eXchange) as it is defined in this document is an appropriate data format for this
purpose. This concept of data exchange is open for different applications.
The main task of a data exchange is transporting/synchronizing information from the P&ID
database to the PCE databases and vice versa. The owner's reference designation system
and a unique description of the processing requirement is the key for a
...
