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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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
This standard is one of the IEC 61970 series that define an application program interface
(API) for an Energy Management System (EMS).
The Part 3 series of IEC 61970 specify a Common Information Model (CIM): a logical view of
the physical aspects of EMS information. The Part 3 series includes Part 301: Common
Information Model (CIM) Base.
This standard is one of the IEC 61970, Part 4 series that define utility control center
component interface specifications (CIS). Part 4 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 Part 5 of this series of standards.
Energy Management Systems display CIM data mostly in tabular lists and graphic schematic
displays. The graphics schematic definitions may be included in the CIM, as defined by the
location package IEC 61968, Part 11, or they may be stored in various proprietary formats.
Part 453 specifies guidelines for the exchange of graphic schematic definitions. Part 553-4
defines the SVG format for exchanging graphic schematic definitions.

1 Scope
This part of IEC 61970 is a member of the Part 450 to 499 series that, taken as a whole,
defines, at an abstract level, the content and exchange mechanisms used for data transmitted
between control center components.
Included in this part of IEC 61970 are the general use cases for exchange of graphic
schematic display definitions, and guidelines for linking the schematic definitions with CIM
data. Guidelines for management of schematic definitions through multiple revisions are also
included.

3 Terms and definitions
The following terms and definitions as well as the entries in the international electrotechnical
vocabulary, IEC 60050, apply.
3.1
domain object
an instance of a class that models a Real-World Object with a unique identity
NOTE A domain object inherits from a CIM IdentifiedObject. A domain object is normally not a graphics object.
3.2
graphics display
electronic equivalent of a seamless paper plan
NOTE The graphics display is an identified container for the graphics objects. Examples of graphics displays
include substation diagrams, transportation or distribution network orthogonal schematics, or pseudo-geographical
schematics. A graphics display has a well-defined coordinate space.

61970-453 © IEC:2008(E) – 7 –
3.3
graphics object
the graphics display is composed of graphics objects. The graphics objects define the
representation of domain objects, static background, or user interaction elements
NOTE An example for domain objects includes breakers. An example for static background object includes lakes,
and an example for user interaction elements includes buttons.
3.4
presentation logic
defines how to render graphic objects possibly based on the state of domain objects
NOTE Typically, the presentation logic is solved in a very specific way for
