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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. 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 this document, 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.
This standard series proposes a method for standardization which will help both suppliers and
users of measuring 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 measuring 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. This standard series 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.
IEC 61987-10 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. IEC 61987-10 also provides the data model for
assembling the LOPs.
IEC 61987-11 specifies the generic structure for operating and device lists of properties (OLOPs
and DLOPs) It lays down the framework for further parts of IEC 61987 in which complete LOPs
for device types measuring a given physical variable and using a particular measuring 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 such as control valves and signal
processing equipment.
IEC 61987-31 concerns infrastructure devices, i.e. devices mostly to be found in the switching
room and the control room. It provides a classification, a generic DLOP and an OLOP for a
range of device types of this device group.
IEC 61987-32 concerns I/O modules. It provides an OLOP for I/O modules that can also be
used for other infrastructure devices and a DLOP for I/O modules that can be used for input
modules, output modules and combined input/output modules of various types.

4.1 Overview
The LOPs provided by this document are intended for use in electronic data exchange
processes performed between any two computer systems. The two computer systems can both
belong to the same company or they can belong to different companies as described in Annex C
of IEC 61987-10:2009.
The OLOP for the family of infrastructure devices is to be found in Annex A while the DLOPs of
the individual I/O modules types are to be found in Annex B.
Structural elements such as LOP type, block and property defined in this document are available
in electronic form in the "Process automation" domain of the IEC Component Data Dictionary
(CDD).
4.2 Examples of DLOP block usage
4.2.1 DLOP for I/O modules
In Table 1, an excerpt of the DLOP for I/O modules with values and units of measure assigned
to the properties is shown. This is a possible configuration for a four-channel binary input
module (see also Figure 1). Not all properties of an LOP have to be used. Thus, in Table 1 there
are empty properties. "…" indicates there a property area that has not been used in the example.
