ELECTRICITY METERING DATA EXCHANGE –
THE DLMS/COSEM SUITE –

Part 6-1: Object Identification System (OBIS)

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 International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this International Standard may involve the use of a maintenance service concerning the stack of protocols on
which the present standard IEC 62056-6-1 is based.
The IEC takes no position concerning the evidence, validity and scope of this maintenance service.
The provider of the maintenance service has assured the IEC that he is willing to provide services under
reasonable and non-discriminatory terms and conditions for applicants throughout the world. In this respect, the
statement of the provider of the maintenance service is registered with the IEC. Information may be obtained from:

INTRODUCTION
The competitive electricity market requires an ever-increasing amount of timely information
concerning the usage of electrical energy. Recent technology developments enable to build
intelligent static metering equipment, which is capable of capturing, processing and
communicating this information to all parties involved.
To facilitate the analysis of metering information, for the purposes of billing, load-, customer-
and contract management, it is necessary to uniquely identify data items, whether collected
manually or automatically, via local or remote data exchange, in a manufacturer-independent
way. The definition of identification codes to achieve this – the OBIS codes – is based on
DIN 43863-3:1997, Electricity meters – Part 3: Tariff metering device as additional equipment
for electricity meters – EDIS – Energy Data Identification System.

THE DLMS/COSEM SUITE –

Part 6-1: Object Identification System (OBIS)



1 Scope
This part of IEC 62056 specifies the overall structure of the OBject Identification System
(OBIS) and the mapping of all commonly used data items in metering equipment to their
identification codes.
OBIS provides a unique identifier for all data within the metering equipment, including not only
measurement values, but also abstract values used for configuration or obtaining information
about the behaviour of the metering equipment. The ID codes defined in this standard are
used for the identification of:
• logical names of the various instances of the ICs, or objects, as defined in
2
IEC 62056-6-2 ;
• data transmitted through communication lines,
• data displayed on the metering equipment, see A.2.
This standard applies to all types of metering equipment, such as fully integrated meters,
modular meters, tariff attachments, data concentrators etc.
To cover metering equipment measuring energy types other than electricity, combined
metering equipment measuring more than one type of energy or metering equipment with
several physical measurement channels, the concepts of medium and channels are
introduced. This allows meter data originating from different sources to be identified. While
this standard fully defines the structure of the identification system for other media, the
mapping of non-electrical energy related data items to ID codes needs to be completed
separately.
NOTE EN 13757-1 defines identifiers for metering equipment other than electricity: heat cost allocators, cooling,
heating, gas, cold water and hot water.
2 Normative references

4 OBIS code structure
4.1 General
OBIS codes identify data items used in energy metering equipment, in a hierarchical structure
using six value groups A to F, see Figure 1.
A B C D E F
IEC  1091/13

Figure 1 – OBIS code structure
4.2 Value group A
Value group A is used to identify the media (energy type) to which the metering is related.
Non-media related information is handled as abstract data.
4.3 Value group B
Value group B is generally used to identify the measurement channel number, i.e. the number
of the input of a metering equipment having several inputs for the measurement of energy of
the same or different types (for example in data concentrators, registration units). Data from
different sources can thus be identified.
Value group B may also be used to identify the communication channel, and in some cases
for other purposes.
The definitions for this value group are independent from the value group A.

---------------------- Page: 11 ----------------------
– 10 – 62056-6-1 © IEC:2013
4.4 Value group C
Value group C is used to identify the abstract or physical data items related to the information
source concerned, for example current, voltage, power, volume, temperature. The definitions
depend on the value in the value group A.
Further processing, classification and storage methods are defined by value groups D, E
and F.
For abstract data, value groups D to F provide further classification of data identified by value
groups A to C.
4.5 Value group D
Value group D is used to identify types, or the result of the processing of physical quantities
identified by values in value groups A and C, according to various specific algorithms. The
algorithms can deliver energy and demand quantities as well as other physical quantities.
4.6 Value group E
Value group E is used to identify further processing or classification of quantities identified by
values in value groups A to D.
4.7 Value group F
Value group F is used to identify historical data, identified by values in value groups A to E,
according to different billing periods. Where this is not relevant, this value group can be used
for further classification.
4.8 Manufacturer specific codes
In value groups B, C, D, E and F, the following ranges are available for manufacturer-specific
purposes:
• group B: 128…199;
• group C: 128…199, 240;
• group D: 128…254;
• group E: 128…254;
• group F: 128…254.
If any of these value groups contain a value in the manufacturer sp
