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 61970-453 has been prepared by IEC technical committee 57:
Power systems management and associated information exchange.
This second edition cancels and replaces the first edition published in 2008. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The SVG elements and its data model have been replaced by the Diagram Layout
Package, which is now an integral part of the IEC 61970-301 (CIM) model.
b) The exchange is in accordance with and is a part of the IEC 61970 profile concept.
c) A glue point object has been introduced to model explicit connections between graphics
elements.

INTRODUCTION
This standard is part of the IEC 61970 series that define an application program interface
1 2
(API ) for an Energy Management System (EMS ).
3
The IEC 61970-3x series specify a Common Information Model (CIM ): a logical view of the
physical aspects of EMS information. The IEC 61970-3x series includes IEC 61970-301,
Common Information Model (CIM) Base.
This standard is one of the IEC 61970-4x series that define utility control centre component
4
interface specifications (CIS ). IEC 61970-4x specifies the functional requirements for
interfaces that a component (or application) shall implement to exchange information with
other components (or applications) and/or to access publicly available data in a standard way.
The component interfaces describe the specific message contents and services that can be
used by applications for this purpose. The implementation of these messages in a particular
technology is described in the IEC 61970-5x series.
Energy Management Systems employ a variety of schematic and quasi-geographic
presentations in their user interfaces. These are sometimes generated automatically, but
more often are hand-drawn and require considerable labour to create and maintain. Most of
this labour goes into the arrangement, or ‘layout’ of the power system elements within the
overall diagram. When network models are exchanged, as defined in IEC 61970-452 and
IEC 61968-13 standards, it is desirable to be able to exchange these layouts.
IEC 61970-453 specifies guidelines for the exchange of diagram layout information for
schematic data that is encoded using IEC 61970-552.

IEC 0423/14
Figure 1 – System overview
An examination of the use cases for such exchanges revealed that the diagrams being
exchanged are not fixed graphic presentations. Instead the diagrams vary considerably in
appearance as attributes of CIM objects change, and they support important user interaction.
For example, a SCADA one-line in its creator’s system is supporting live control of the power
system, while in a receiver’s system it is merely used for reference so that a neighbour can
understand what the system looks like beyond its own border. These variations are typically
not easy or appropriate to map between the source and receiving systems because of the
degree of difference in the way those systems are designed.
In the specification of diagrams, one common element is that the style of displaying an object
of a certain kind is usually defined once and then re-used, but the placement of objects must
be adjusted whenever new elements are added to the data model. This placement and
maintenance of placement is where most of the labour investment takes place that users
would like to preserve. As a result, this standard is limited to the exchange of diagram layouts
(meaning the arrangement of CIM objects in a display space) rather than a complete
exchange of all characteristics of a graphic presentation.
With this proposed standard, instead of maintaining duplicate schematics for different
applications, the schematics are exported by one system and imported by the other system.
Diagram layout profile is an extension to the CIM power system model exchange IEC 61970-
452, and will be orchestrated along with the existing CIM XML model exchange and updates
provided using the existing CIM XML Incremental file format as defined in IEC 61970-552.
IEC 61970-552 also describes how payload headers provide information as to how payloads
fit together.

This process can be applied for initial schematics construction as well as for continuous
maintenance.
The importing system can create its graphics displays from the imported data, or the diagram
layout data can serve as additional documentation and means of understanding for the
domain data exchange.
4.2 Simple bay diagram example
Diagrams are constructed using different approaches. This subclause illustrates this using a
simple bay drawing. Figure 2 shows a typical representation of a bay.
IEC 0424/14
Figure 2 – Bay diagram as rendered
In a GIS system, lines are typically drawn up to the centre point of the symbol. This is shown
in Figure 3 (transparent symbol is used for illustration). This construction method is
independent if the symbol size, i.e. the drawing looks “pretty” even when the importing system
used a smaller symbol size than the original one.

Figure 3 – Bay diagram drawn in GIS style
In a SCADA system, lines are typically drawn to align with the terminals of the object
represented by the symbol. This is shown in Figure 4 (transparent symbol is used for
illustration). This construction method gives a closer representation of the electrical topology,
but depends on a certain symbol size.

5 Diagram layout exchange profile
5.1 General
Profile namespace: http://iec.ch/TC57/61970-453/DiagramLayout/2#
This standard specifies an exchange profile for schematics with the following characteristics.
• A generic method for linking the diagram object to the domain data. Domain data and
diagram layout data can be exchanged together with the domain data, or separately from
each other with the assumption that domain data will have already been imported should
diagram layout data be imported separately.
• It does not require or imply a specific domain data format. Therefore, it supports domain
data modelled according to the IEC 61970-301 Common information model (CIM) that is
exchanged in the IEC 61970-501 format (CIM RDF schema). Diagram layout data
references domain data in compliance with IEC/TR 62541-1, OPC Unified Architecture).
• The intended usage of this standard is that the source of a diagram will use the standard
to encode the layout of their diagram as they created it. It is then incumbent upon any
receiver to supply the means of using that diagram layout in their system.
– In the simplest situation, if the source uses Switch object placements, the receiver
creates a generic Switch template in the receiver’s system that will be used to render
Switches (i.e. there is no exchange of Switch templates).
– In more complex situations, a 1:1 correspondence may not be desirable, and receivers
may have to create generic transformations in order to use exchanges.
– However, in both situations, it is expected that once an investment is made in a
strategy for rendering, repeated imports may be carried out automatically.
• Supports the exchange of diagram objects that have no relationship to domain data, i.e.,
pure static background objects.

• Supports multiple representations of the same domain object in the same or different
diagrams.
• Allows the diagram to be used as the unit of exchange, providing a straightforward
approach to partial exchange, or an exchange between systems that have a separate
model and repository for diagram layout data.
• Supports assignment of diagram objects to layers or other means, for showing or hiding
information based on zoom level and/or user interest.
