AMENDMENT 1
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 61850-1-2:2020 has been prepared by IEC technical committee 57: Power
systems management and associated information exchange.
The text of this Amendment is based on the following documents:
Draft Report on voting
57/2370/DTS 57/2408/RVDTS
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this Amendment is English.

 IEC 2022
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The "colour inside" logo on the cover page of this document indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

____________
Replace, throughout the document (with the exception of Subclause 6.1.7), "http" with "https".
3 Terms and definition
Add, between 3.1 and 3.2, the following new term:
3.14
deprecation (of an element of a given model)
action consisting in tagging this element specifically in order to discourage future usage of this
element
Note 1 to entry: The deprecation of an element implies the deprecation of all included sub-elements.
Note 2 to entry: A deprecation is often the latest stage before withdrawing a given element.
Note 3 to entry: Once deprecation has applied to an element, this element is tagged as "deprecated".
Note 4 to entry: Deprecation may apply to any types of element of the model, including (but not restricted to)
attribute, class, object, abbreviation, enumerated element, package, namespace.

6.1.5.2 Document introduction
Replace the existing text of Subclause 6.1.5.2 by the following new text:
As soon as code components are attached to the deliverables some "legal” specific information
need to be added to the foreword (refer to section 5 of the guidelines document for handling
code component as introduced in 6.1.4.2).
It is highly recommended to have namespace related information (see 6.1.6.2) included in
Clause 1 of any IEC concerned publication (part of the scope).

– 4 – IEC TS 61850-1-2:2020/AMD1:2022
 IEC 2022
More specifically, Clause 1 of such document should be broken down as below:
• Clause 1: Scope
• Subclause 1.1: General
As usual …
• Subclause 1.2:
In Clause 1, "Scope", a Subclause 1.2 "Published versions of this standard and related
namespace name” shall be added with a table that provides a reference between all IEC
editions, amendments or corrigenda and the full name of the namespace as shown in
Table 10:
Table 10 – Reference between published versions
of the standard and related namespace name
Edition Publication date Webstore Namespace NSD
Edition 1.0 2003-05 IEC 61850-7-3:2003 IEC 61850-7-3:2003
Edition 2.0 2010-12 IEC 61850-7-3:2010 IEC 61850-7-3:2007

If the deliverable includes more than one namespace, additional columns shall be added.
• Subclause 1.3: Identification of the namespaces included in this IEC deliverable
For all the namespaces, the following information shall be provided:
– The nameplate of the namespace with identifier, version, revision and release and
associated code components
– Namespace dependencies
Depending on the namespace technology, additional information may be provided (see
6.1.6.2 for further details related to data model namespaces and to 6.1.7 for XML
namespaces)
• Subclause 1.4 "Code component distribution”
As soon as at least one code component is present in an IEC deliverable, a Subclause 1.4
"Code component distribution" shall be added with some general explanations about code
components and the description of the available code components per namespace (refer to
section 5 of the guidelines document for handling code component as introduced in 6.1.4.2).
Typically this subclause shall start with the following generic explanation about the distribution
of the code component:
"This document is associated with code components.
Each code component is a ZIP package containing at least the electronic representation of the
code component itself and a file describing the content of the package (IECManifest.xml)."
If further versions/revisions may apply, due to some maintenance works, the above shall then
be followed by the following:
"The life cycle of a code component is not restricted to the life cycle of this document. 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 the code component in case of urgent fixes of InterOp Tissues, thus without need
to publish an amendment.
Consequently, new release(s) of the code domponent(s) may be released, which supersede(s)
the previous release, and will be distributed through the IEC web site at:

 IEC 2022
https://www.iec.ch/tc57/supportdocuments.
The latest version/release of the document will be found by selecting the file for the code
component with the highest value for VersionStateInfo, e.g.
IEC_61850-7-3.NSD.{VersionStateInfo}.Light.zip.”
For each code component, the following shall be described:
– The reference to the schema file or any other file that describes the format of the code
component
– If there is a full and light version available or only a full version
– The technical content of the code component
An example of this is as follows:
"The Code Components associated with this document are reflecting the data model specified
in this document formatted in NSD files as described in IEC 61850-7-7. They are available in
light and full version:
– The full version contains definition of the whole data model defined in this standard with the
documentation associated and access is restricted to purchaser of this part
– The light version does not contain any documentations but contains the whole data model
as per full version"
This shall be followed by a link to the code component that can be downloaded (note if the code
component is only published as a full version, that will be the one that is freely downloadable;
otherwise it will be the light version). An example is as follows:
"The light version is freely accessible on the IEC website for download at:
https://www.iec.ch/tc57/supportdocuments, but the usage remains under the licensing
conditions."
Because IEC de facto publishes the same content through two channels (the document and the
code component), an additional sentence shall also indicate for each code component, which
publication is of highest priority in case of differences/discrepancies:
If the downloadable code is of highest priority (typically because of maintenance work):
"In case of any differences between the downloadable code and the IEC pdf published content,
the downloadable code(s) is(are) the valid one; it may be subject to updates. See history files."
If the pdf published version is of highest priority:
"In case of any differences between the downloadable code and the IEC pdf published content,
the IEC pdf published content is the valid one."
