FOREWORD
This amendment 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 2003.
Compared to the first edition, this second edition:
• defines new common data classes used for new standards defining object models for other
domains based on IEC 61850 and for the representation of statistical and historical data;
• provides clarifications and corrections to the first edition of IEC 61850-7-3;
Compared to the second edition, this first revision of the second edition:
a) provides clarifications and corrections to the second edition of IEC 61850-7-3, based on the
tissues = { 690, 691, 692, 697, 698, 707, 709, 711, 722, 814, 816, 819, 832, 839, 846, 868,
887, 919, 924, 925, 926, 929, 953, 954, 962, 968, 996, 1078, 1079, 1122, 1127, 1184, 1187,
1189, 1220, 1233, 1240, 1242, 1247, 1253, 1265, 1270, 1311, 1372, 1387, 1388, 1403,
1430, 1438, 1578, 1581, 1598, 1602, 1623 };
b) includes semantic of attributes within tables in Clauses 6 and 7 and thus removes the need
for explicit semantic definition in Clause 8;
c) Clause 8 now contains definitions of newly introduced explicit enumerated types (with
tables); this is fully backward compatible as the value of the literals have not changed;
d) some subclauses in Clause 7 have different numbering because of introduction of some
abstract types (that group common attributes for several concrete types);
e) first subclause under any CDC group in Clause 7, that contained the tables with applicable
services with respect to functional constraints, have been removed; that information is
explicitly defined in IEC 61850-7-2 with functional constraints, and temporarily included as
Annex B, Functional constraints;
f) contents of 6.2.7 and 6.2.8 have been moved to the normative Annex D of IEC 61850-7-2:
Clarification on usage of quality;
g) implements extension introduced by IEC 62351-6 for security;
h) presence conditions have been redesigned and renamed to support their uniform usage in
all of the IEC 61850-7-xxx series as necessary. Below is the table containing the old and
the new presence conditions:

networks and systems for power utility automation, can be found on the IEC website.
Contrary to usual IEC practice, for ease of use in this case, all tables and figures (including
those which have been added since Edition 2) have been numbered consecutively in the
amendment and the consolidated version.
This IEC standard includes Code Components i.e. components that are intended to be directly
processed by a computer. Such content is any text found between the markers BEGINS> and , or otherwise is clearly labeled in this standard as a Code
Component. In the current version of this document, such indication is made at the beginning
of each concerned top-level clause.

INTRODUCTION
This document is part of a set of specifications, that details layered substation communication
architecture. This architecture has been chosen to provide abstract definitions of classes and
services such that the specifications are independent of specific protocol stacks and objects.
The mapping of these abstract classes and services to communication stacks is outside the
scope of IEC 61850-7-x and may be found in IEC 61850-8-x (station bus) and IEC 61850-9-x
(process bus).
IEC 61850-7-1 gives an overview of this communication architecture. This part of IEC 61850
defines constructed attributed classes and common data classes related to applications in the
power system using IEC 61850 modeling concepts such as substations, hydro power or
distributed energy resources. These common data classes are used in IEC 61850-7-4 to define
compatible dataObject classes. The SubDataObjects, DataAttributes or SubAttributes of the
instances of dataObject are accessed using services defined in IEC 61850-7-2.
This part of IEC 61850 is used to specify the abstract common data class and constructed
attribute class definitions. These abstract definitions are mapped into concrete object definitions
that are to be used for a particular protocol (for example MMS, ISO 9506 series).
Some restructuration of the document was done between Edition 2 and Ed 2.1. The following
table provides a cross reference.

for download, but the usage remains under the licensing conditions.
The link for downloading the light version of this code component is:
http://www.iec.ch/public/TC57/supportdocuments/IEC_61850-7-3.NSD.2007B3.light.zip

The Code Components for IEC 61850 data models (like basic types, presence conditions, …
definition in this IEC standard) are available as the file format NSD defined by standard
IEC 61850-7-7.
The Code Component(s) included in this IEC standard are potentially subject to maintenance
works and user shall select the latest release in the repository located at:
http://www.iec.ch/TC57/supportdocuments

The latest version/release of the document will be found by selecting the file IEC_61850-7-
2.NSD.{VersionStateInfo}.light.zip with the filed VersionStateInfo of the highest value.

Each Code Component is a ZIP package containing the electronic representation of the Code
Component itself, with a file describing the content of the package (IECManifest.xml).
The IECManifest contains different sections giving information on:

– 10 – IEC 61850-7-3:2010/AMD1:2020
© IEC 2020
– The copyright notice
– The identification of the code component
– The publication related to the code component
– The list of the electronic files which compose the code component
– An optional list of history files to track changes during the evolution process of the code
component
The life cycle of a code component is not restricted to the life cycle of the related publication.
The publication life cycle goes through two stages, Version (corresponding to an edition) and
Revision (corresponding to an amendment). A third publication stage (Release) allows
publication of Code Component without need to publish an amendment.
This is useful when InterOp Tissues need to be fixed. Then a new release of the Code
Component will be released, which supersedes the previous release, and distributed through
the IEC TC57 web site.

6.1 General
Add the following new paragraph before the existing first paragraph of Subclause 6.1:
The constructed attribute classes structure and descriptions are part of the Code Component
of this IEC standard and are available as electronic machine readable file in related NSD file.
6.2 Quality
Delete existing Subclauses 6.2 and 6.3 and renumber subsequent subclauses accordingly.
6.2 Configuration of analogue value (ScaledValueConfig)
Replace the existing text of this subclause with the following new text:
This type shall be used to configure the integer value representation of the analogue value. See
AnalogueValue.i.
NOTE If a server does not support transmission of floating point values, the client may retrieve these values from

This clause groups all the variants of the analogue value types used for monitoring, control,
settings and tracking.
6.11.2 Analogue value (AnalogueValue)
Analogue values may be represented as a basic type integer (attribute 'i') or as a floating point
(attribute 'f'). At least one of the attributes shall be used. If both 'i' and 'f' exist, the application
in the server shall insure that both values remain consistent. When the analogue values
represent measured process value, they shall be the primary values.
NOTE Except for the usage in the CDC SAV, it is recommended to support the representation as a floating point
(attribute 'f') since the representation as an integer (attribute 'i') may be deprecated in the future.

7 Common data class specifications
7.1 General
Replace the existing text of Subclause 7.1 with the following new text:
The common data classes structure and descriptions are part of the Code Component of this
IEC standard and are available as electronic machine readable file in related NSD file.
Common data classes are defined for use in IEC 61850-7-4. Common data classes are
composed of the following:
– constructed attribute classes defined in Clause 6,
– types defined in IEC 61850-7-2,
– common data classes defined in this clause,
– enumerated data attribute types defined in Clause 8.
The common data classes define the relation between their attributes and the functional
constraint as well as the possible trigger options. Sometimes, both dchg and dupd are specified
as a possible trigger option for the DataAttribute. In that case, the concrete implementation
shall select one of them, based on the purpose of the data object typed by that common data
class.Trigger option dchg shall be used for DataAttribute where a change of the value is
necessary to create an event, whereas trigger option dupd shall be used for DataAttribute where
an update of the value (with or without change) is enough to create an event.

Figure 3 – Class diagram CommonDataClasses::CommonDataClasses
Figure 5: This diagram shows all the common data class groups, with their contents.
Classes displayed in italic and ending with "CDC" are abstract common data classes that allow
avoiding duplication in definition of attributes used by multiple concrete common data classes.
Abstract common data classes are never instantiated; their attributes are inherited by concrete
common data classes which are instantiable.
