FOREWORD
This amendment has been prepared by IEC technical committee 57: Power systems
management and associated information exchange.
The motivation and goal of the amendment is to improve consistency of the data model over
all application domains of IEC 61850. Data (Logical Nodes, Data Objects, Data Attributes)
with the same semantics shall have the same naming where this part of IEC 61850 refers to
Logical Nodes and Data Objects and IEC 61850-7-3 to the Data Attributes.
Therefore, the amendement complements and updates the second edition of this part of
IEC 61850, which was published in 2010. It constitutes editorial revisions for consistency and
technical corrections of bugs as far as interoperability is touched.
To reach this goal and to keep it for all future as common working source a comprehensive
back-office UML version was created and will be maintained for future standard development.
The published parts of IEC 61850such as IEC 61850-7-4, on which the amendment is based,
are generated automatically from the UML version. This allows publishing, voting and reading
the various parts of IEC 61850-7 as in the past.
This amendment includes the following changes with respect to IEC 61850-7-4:2010:
• provides clarifications and corrections to the second edition of IEC 61850-7-4, based on
the tissues = {671, 672, 674, 675, 676, 677, 679, 680, 682, 683, 685, 686, 689, 693, 694,
695, 696, 712, 713, 714, 715, 716, 724, 725, 732, 734, 735, 736, 742, 743, 744, 748, 749,
772, 773, 774, 775, 776, 800, 802, 808, 819, 830, 831, 835, 838, 842, 843, 844, 849, 871,
877, 878, 879, 881, 882, 902, 908, 909, 910, 911, 912, 913, 920, 928, 932, 933, 937, 939,
940, 952, 967, 991, 1007, 1029, 1044, 1046, 1071, 1075, 1076, 1077, 1081, 1086, 1117,
1119, 1128, 1137, 1139, 1176, 1177, 1190, 1191, 1203, 1205, 1229, 1235, 1236, 1244,
1250, 1256, 1258, 1259, 1261, 1269, 1273, 1278, 1282, 1292, 1294, 1310, 1316, 1330,
1331, 1333, 1339, 1347, 1348, 1364, 1368, 1375, 1380, 1390, 1404, 1411, 1420, 1423,
1425, 1426, 1456, 1568};
• adds to each functional LN group a parent abstract Logical node where the functional
nodes are children from (full object oriented model). Since all abstract LNs are in a
common clause, the relative position of the functional LNs is not changed within their
clause.
• adds new abbreviated terms
• has extension of the list of abbreviate terms to be used for object names
• has more precise combination rules for abbreviated terms to object names
• has extensions by new logical nodes mainly from power quality domains and others
• has corrections of editorial errors.
Clauses 4 through 8 and their subclauses (except for 5.1, 5.2, and 5.3) and XML
enumerations from Annex H are automatically generated from the UML model.
The structure of the document has been changed for the following reasons:
– To split the description of logical nodes preliminaries (Clause 5) from logical node
specification (Clause 6). Some content of this clause has been moved from the previous
description of logical nodes (was in IEC 61850-7-4:2007(revision A – 5.1 and 5.2).
– To include abstract logical nodes. These abstract logical nodes have been described in
6.2.
– The specification of logical nodes begins with 6.3 (was in IEC 61850-7-4:2007 (revision A
– 5.3). In consequence all clauses in IEC 61850-7-4:2007 (revision A beginning with 5.3
count one number higher (beginning with 6.3) than they were in IEC 61850-7-4
(revision A).
IEC 61850-7-4:2010/AMD1:2020 – 3 –
 IEC 2020
– The description of data object semantics and enumerations starts with Clause 7. A new
clause has been included to specify the enumerations used in IEC 61850-7-4 separately.
Annex J and Annex K have been added.
The text of this amendment is based on the following documents:
FDIS Report on voting
57/2102A/FDIS 57/2133/RVD
Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The content of this part of IEC 61850 is based on existing or emerging standards and
applications. In particular the definitions are based upon:
• the specific data objects types defined in IEC 60870-5-101 and IEC 60870-5-103;
• the common class definitions from the Utility Communication Architecture 2.0: Generic
Object Models for Substation and Feeder Equipment (GOMSFE) (IEEE TR 1550);
• CIGRE Report 34-03, Communication requirements in terms of data flow within
substations, December 1996.
A list of all parts of the IEC 61850 series under the general title Communication networks and
systems for power utility automation, can be found on the IEC website.
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 clauses
The purchase of this IEC standard carries a copyright license for the purchaser to sell
software containing Code Components from this standard directly to end users and to end
users via distributors, subject to IEC software licensing conditions, which can be found at:
http://www.iec.ch/CCv1.
If any updates are required to the published code component that needs to apply immediately
and can not wait for an amendment (i.e. fixing a major problem), a new release of the Code
Component will be issued and distributed through the IEC WebSite. Any new release of the
Code Component related to this part will supersede any previously published Code
Component including the one published within the current document.
This publication contains attached nsd files which compose the Code Component of this part.
These files are intended to be used as a complement and do not form an integral part of this
standard.
