This part of IEC 61987 provides
• operating list of properties (OLOP) for the description of the operating parameters and the
collection of requirements for level measuring equipment, and
• device lists of properties (DLOPs) for the description of a range of level measuring
equipment types.
The structures of the OLOP and the DLOPs correspond to the general structures defined in
IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in
IEC 61987-10.
Aspects other than the OLOP, needed in different electronic data exchange processes
described in IEC 61987-10, will be published in IEC 61987-921.
The locations of the libraries of properties and of blocks used in the LOPs concerned are
listed in the Annexes C and D.

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 61987-15 has been prepared by subcommittee 65E: Devices and

integration in enterprise systems, of IEC technical committee 65: Industrial-process

measurement, control and automation.
The text of this standard is based on the following documents:

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.

IEC 61987 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. IEC 61987 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 61987-15 concerns level measuring equipment. It provides one operating LOP for all

types of level measuring equipment which can be used, for example, as a request for various

sorts of quotation. The DLOPs for the various level transmitter and gauge types provided in

this part of IEC 61987 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 different plant maintenance systems of the

plant owners. The OLOP and the DLOPs provided correspond to the guidelines specified in

IEC 61987-10 and IEC 61987-11.
