REPRESENTATION OF ELECTRICAL & INSTRUMENTATION OBJECTS IN
DIGITAL 3D PLANT MODELS DURING ENGINEERING

Engineering of process plant instrumentation – 3D model requirements

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 63261 has been prepared by subcommittee SC65E Devices and
integration in enterprise systems, of IEC technical committee SC65E WG 13.

INTRODUCTION
Engineering and construction in the process industries typically require the cooperation of
multiple companies.Due to economic reasons, special knowledge, special license, authorization
or simply capacity utilization the work is divided between partners. They will arrange their
cooperation for each individual project differently. This requires well defined divison of work
and responsibilities across the different phases of project execution.
Efficient engineering of a digital 3D plant model requires highly sophisticated tools for the
different needs of the involved work processes and departments. By nature of the plant model
all engineering disciplines meet in the model and need clear definitions of the content and
interfaces.
Digital 3D plant models play an important part in electrical and instrumentation engineering to
create technical drawings and avoid clashes between the elements provided by different
engineering disciplines.
The first aim of this standard is to define the level of details of electrical and instrumentation
equipment representations placed in the 3D plant model. It specifies minimum requirements at
the different maturity grades of the model for each equipment, its related metadata and reports
retrieved from the 3D plant model.
The second aim of this document is to define a timeline and project milestones with the
associated level of detail for the incorporation of electrical and instrumentation equipment into
the 3D plant model.
This document aims at avoiding misunderstandings and erroneous design work in order to
reduce additional corrective works and expenses for clarification.

Engineering of process plant instrumentation – 3D model requirements

1 Scope
This document provides requirements for the E&I objects of a digital 3D plant model, used in
the engineering phase to design and construct a process plant and its instrumentation. It
provides guidance how to model plants and their electrical and instrumentation equipment.
This document also specifies the content and the possible output of the 3D plant model at
project milestones.
This document can be used by the contractual partners to agree upon the content
