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 61987-92 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.

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 standard, 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 may 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 may 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 may 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 61987-12 to IEC 61987-16 specify the OLOPs and DLOPs for measuring equipment for
flow, pressure, temperature, level and density measurement respectively. Whereas a DLOP
describes a device itself, an OLOP describes the most important aspect of a device, namely
the conditions and infrastructure to be found at the point of installation. Thus, it contains the
ambient conditions and the technical requirements that the device must fulfil during operation.
IEC 61987-92 contains additional aspects that are common to all devices, for example,
“Packaging and transportation”, “Calibration and test results” and “Device documents
supplied”. The associated LOPs can accompany any DLOP as described in IEC 61987-11.

4.5 Qualifiers
An important attribute of a dynamic digital communication parameter, e.g. a value output by a
block, is the time at which the sampling was made. In practice, this information is provided by
a time stamp. The time stamp is not a property in itself, but a so-called qualifier.
Qualifiers provide additional information to a value assigned to a property, an instance of the
property and the respective LOP or are assigned to a LOP as a whole. The qualifier concept
is defined in IEC 61360-1.
– 14 – IEC 61987-92:2018 © IEC 2018
Another example of a qualifier is the life cycle qualifier. This is defined in IEC 62569-1 where
further useful value qualifiers are to be found. In the IEC CDD, these qualifiers are found in
the domain “IEC 61360-4” under “feature” (0112/2///61360_4#AAA233) in the class “qualifier”
(AAB001).
The qualifier “time stamp” is to be found in the IEC CDD in the domain Process automation in
the List of Qualifiers (ABJ604) under ABA000 ABV001.
The time stamp qualifier has the ID: IEC-ABJ605:
preferred name time stamp

element type the qualifier is assigned to has been created or changed
