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.

INTRODUCTION
The exchange of product data between companies, business systems, engineering tools, data
systems within companies and, in the future, control systems (electrical, measuring and
control technology) can run smoothly only when both the information to be exchanged and the
use of this information has been clearly defined.
Prior to IEC 61987, requirements on process control devices and systems were specified by
customers in various ways when suppliers or manufacturers were asked to quote for suitable
equipment. The suppliers in their turn described the devices according to their own
documentation schemes, often using different terms, structures and media (paper, databases,
CDs, e-catalogues, etc.). The situation was similar in the planning and development process,
with device information frequently being duplicated in a number of different information
technology (IT) systems.
Any method that is capable of recording all existing information only once during the planning
and ordering process and making it available for further processing, gives all parties involved
an opportunity to concentrate on the essentials. A precondition for this is the standardization
of both the descriptions of the objects and the exchange of information.
IEC 61987 (all parts) propose a method for standardization which will help both suppliers and
users of process control equipment to optimize workflows both within their own companies
and in their exchanges with other companies. Depending on their role in the process,
engineering firms can be considered here to be either users or suppliers.
The method specifies process control equipment by means of blocks of properties. These
blocks are compiled into lists of properties (LOPs), each of which describes a specific
equipment (device) type. IEC 61987 (all parts) covers both properties that can be used in an
inquiry or a proposal and detailed properties required for integration of the equipment in
computer systems for other tasks.
Part 10 of IEC 61987 defines structure elements for constructing lists of properties for
electrical and process control equipment in order to facilitate automatic data exchange
between any two computer systems in any possible workflow, for example engineering,
maintenance or purchasing workflow and to allow both the customers and the suppliers of the
equipment to optimize their processes and workflows. Part 10 also provides the data model
for assembling the LOPs.
Part 11 of IEC 61987, while specifying a generic structure for measuring equipment, provides
several important detail descriptions, such as the handling of composite devices that are also
required for LOPs describing devices of other areas like the automated valves.
Part 21 of IEC 61987 specifies the generic structure for operating and device lists of properties
(OLOPs and DLOPs) for automated valves. It lays down the framework for further parts of
IEC 61987 in which complete LOPs for final control elements of different construction and
functional principle will be specified. The generic structure can also serve as a basis for the
specification of LOPs for other industrial-process control instrument types.
This part of IEC 61987 concerns flow modification accessories. It provides operating LOPs which
can be used, for example, as a request for quotation for various purposes. The DLOPs for the
accessories provided in this document can be used in very different ways in the computer
systems of equipment manufacturers and suppliers, in CAE and similar systems of EPC
contractors and other engineering companies and especially in the various plant maintenance
systems of plant owners. The OLOP and the DLOPs provided correspond to the guidelines
specified in IEC 61987-10, IEC 61987-11 and IEC 61987-21.
