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 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 quantity 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 concerns flow measuring equipment. It provides one operating LOP for all types
of flow transmitter which can be used, for example, as a request for various sorts of quotation.
The DLOPs provided in this standard for a range of flow transmitter types 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 used by plant owners. The OLOP and the DLOPs
provided correspond to the guidelines specified in IEC 61987-10 and IEC 61987-11.

Part 12: Lists of properties (LOPs) for flow measuring
equipment for electronic data exchange

1 Scope
This part of IEC 61987 provides an
• operating list of properties (OLOP) for the description of the operating parameters and the
collection of requirements for a flow measuring equipment and
• device lists of properties (DLOP) for the description of a number of flow measuring
equipment types.
The structures of the OLOP and the DLOP 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 61987-92 .
Libraries of properties and of blocks used in the LOPs in this standard are listed in Annex C
and Annex D.

Under consideration
4 General
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 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 flow measuring equipment is to be found in Annex A while the
DLOPs of the individual flow device types are to be found in Annex B.
Structural elements such as LOP type, block and property defined in this standard are
available in electronic form in the “Automation equipment” domain of the IEC Common Data
Dictionary (CDD).
4.2 Depiction of OLOPs and DLOPs
4.2.1 General
The properties of the OLOPs and DLOPs used in this part of IEC 61987 have been created in
conformance to the requirements of the IEC 61360 series. As such, the structural elements,
properties and attributes to be found in the IEC Common Data Dictionary are normative.
4.2.2 Structural roles
The entities within a list of properties can have one of a number of structural roles.
a) Property
A property exists as a property only.
b) Ref. property + Block
A reference property connects a block to the superordinate block or LOP in which it is
embedded.
Properties and sub-blocks listed below a block name and placed one position to the right
are elements of the block. A block ends when another block name appears in the same
column as the block name or in any other column to its left.
The reference property has the same preferred name as the block to which it refers. All
attributes of these properties are available in the IEC Common Data Dictionary (CDD).
c) Cardinality property
A cardinality property is connected to the block which immediately follows it. The value of
the property (0 … n) in a transaction file determines the number of times the associated
block shall be repeated. It is identified by the identifier in the column “Property identifier”.
The preferred name of a cardinality property is “Number of “, where is
derived from name of the block with which it is associated.
In the transaction file (see examples in 4.3), it can be seen that a block has been repeated
twice:
– the cardinality property directly before the block has a value greater than 1,
– the name of the repeated block is extended by “_” followed by the repetition number.
Example:
If the block “Signal function” is repeated 3 times, the following construction occurs in the transaction file:
“number of signal function” has the value “3” - cardinality property
“Signal function_1” - first repeated block
…
“Signal function_2” - second repeated block
…
– 8 – IEC 61987-12:2016  IEC 2016
“Signal function_3” - third repeated block
…
d) Ref. property + Block
This role is similar to b) but the block concerned can be repeated according to value of the
cardinality property which precedes it.
e) Polymorphic control property
A polymorphic control property provides the means of introducing complete blocks of
properties describing different realizations of a particular device function, for instance
inputs and outputs. The property has a value list containing the designations of the blocks
that may be introduced. When in a transaction file a polymorphic control property is
assigned a value, the corresponding block follows (see examples in Tables 2 and 3).
A polymorphic control property is identified in the IEC Common Data Dictionary by the
identifier in the column “Property identifier”. The preferred name of a polymorphic property
is “ type“, where is normally the derived from name of the block with which
it is associated.
f) Ref. property + Polymorphic block
This role is similar to b) but the block concerned is created by polymorphism.
g) Polymorphic control property with the fixed value: “”
This property appears directly behind the polymorphic block property. It is the same
property as the polymorphic control property for the block, but with the fixed value used to
create the block (see IEC 61987-10).
4.2.3 Marking of polymorphic areas
To help identify the possible polymorphic blocks in a list of properties in a printable version of
this standard, a number with grey background has been added to the rightmost column of the
DLOP to indicate the properties associated with the block. It should be noted that in
transaction file, only the polymorphic block selected from value list of the polymorphic control
property would appear in the superordinate block.
Block Name (containing a polymorphic area)
Properties and sub-blocks
(of the common part, valid for all alternative cases)

Name of the polymorphic control property (which has a value list consisting
of exactly n values)
Block Name (for alternative case 1)
Properties and sub-blocks
(for alternative case 1)
Block Name (for alternative case 2)
Properties and sub-blocks
(for alternative case 2)
…
Block Name (for alternative case n)
Properties and sub-blocks
(for alternative case n)
IEC
Figure 1 – Structure of a polymorphic area

Every polymorphic area corresponds to a block, the structure of which is shown in Figure 1. A
polymorphic area begins with the name of this block containing this area.
The block name can be optionally followed by any number of additional properties or sub-
blocks, provided that they are valid for all alternative sub-blocks that can be generated by the
polymorphism.
The polymorphic control property follows, by means of which one of the alternative blocks can
be selected. The alternative sub-blocks with their properties and sub-blocks are now listed
one after the other.
The polymorphic area ends with the last property of the last sub-block that can be selected
using the value list of the polymorphic control property.
In order to facilitate the analysis of the LOPs the following non-normative numerical marking
system has been used. A polymorphic area can have one or more subordinate, polymorphic
areas embedded in it. Table 1 shows the structure of the polymorphic areas implemented in
the DLOPs of Annex B. In Table 1, each individual polymorphic area has been assigned a
unique number. The areas have been numbered in the sequence which they occur in the LOP,
not according to their level in the structure. The number of an embedded area has therefore a
marking number greater than the marking number of area in which it is embedded.
For example, the majority of the content of the “Output” block is generated from the
polymorphic area marked with the number 8, which starts at “Type of output” and can include
any of the specializations which also are marked with the number 8. Each specialization also
includes in this case a further polymorphic area, “Assigned variable” which is marked by its
own number (>8).

Structural design
Structural design of a thermal mass flow transmitter
In the OLOP for flow measuring equipment, there is only one polymorphic area. It appears in
the block “Phase”.
In order to make clear how the structural elements such as block, cardinality and
polymorphism can be implemented using the LOPs of this standard some examples are
provided in 4.3.
4.3 Examples of DLOP block usage
4.3.1 Block “Input”
A Coriolis mass flowmeter with DN25 process connections has three input variables: mass
flow, density and temperature. An additional binary voltage input can be configured to operate
a totalizer reset or to start/stop batching. The Input block in the DLOP is configured as shown
in Table 2 (… indicates a property or properties that have not been used; grey shading
indicates polymorphism).
