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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC TS 61850-80-4, which is a technical specification, has been prepared by IEC technical
committee 57: Power systems management and associated information exchange.

INTRODUCTION
IEC 61850 defines communication networks and systems for power utility automation, and
more specifically the communication architecture for subsystems such as substation
automation systems, feeder automation systems and SCADA for distributed energy resources.
In essence, IEC 61850 is a description of the communication architecture for the overall
power system management when the combined total of the above mentioned subsystems are
considered.
The devices in the electricity grid are becoming more intelligent with an increasing number of
elements and increasing complexity of data to be processed in a distributed environment.
Introduction of comprehensive data models simplifies the handling and management of the
data drastically since the models can be re-used once standardized. By defining a number of
standardized hierarchical names, it can drastically reduce errors in the field. The names in the
standard can be directly used for the configuration of devices and the communication between
devices.
This part of IEC 61850, which is a technical specification, defines the one-to-one relationship
of IEC 62056 OBIS codes to IEC 61850 Logical Nodes. The purpose is to increase the
availability of revenue meter information to other applications defined within the IEC 61850
framework. This increased visibility will contribute to information available for smart grid
applications.
The other benefit of defining these relationships is in regards to the design of protocol
converters. With a cle
