Electricity metering - Data exchange for meter reading, tariff and load control -- Part 61: Object identification system (OBIS)

The OBject Identification System (OBIS) defines the identification codes (ID-codes) for commonly used data items in electricity metering equipment. This part of IEC 62056 specifies the overall structure of the identification system and the mapping of all data items 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 interface classes, or objects, as defined in IEC 62056-62; data transmitted through communication lines, see Clause A.1; data displayed on the metering equipment, see Clause A.2. This standard applies to all types of electricity 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.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62056-61 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

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.
For further analysis of this information, for the purposes of billing, load, customer and contract
management, it is necessary to uniquely identify all data in a manufacturer independent way,
collected manually or automatically, via local or remote data exchange.
The definition of identification codes is based on DIN 43863-3:1997.

ELECTRICITY METERING – DATA EXCHANGE FOR
METER READING, TARIFF AND LOAD CONTROL –

Part 61: Object identification system (OBIS)



1 Scope
The OBject Identification System (OBIS) defines the identification codes (ID-codes) for
commonly used data items in electricity metering equipment. This part of IEC 62056 specifies
the overall structure of the identification system and the mapping of all data items 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 interface classes, or objects, as defined in
IEC 62056-62;
• data transmitted through communication lines, see Clause A. 1;
• data displayed on the metering equipment, see Clause A. 2.
This standard applies to all types of electricity 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.

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  302/02
Figure 1 – OBIS code structure
4.2 Value group A
The value group A defines the media (energy type) to which the metering is related. Non-
media related information is handled as abstract data.
4.3 Value group B
The value group B defines the 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
(e.g. in data concentrators, registration units). Data from different sources can thus be
identified. The definitions for this value group are independent from the value group A.
4.4 Value group C
The value group C defines 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 of 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
The value group D defines types, or the result of the processing of physical quantities
identified with the 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
The value group E defines further processing or classification of quantities identified by value
groups A to D.
4.7 Value group F
The value group F defines the storage of data, identified by value groups A to E, according to
different billing periods. Where this is not relevant, this value group can be used for further

ELECTRICITY METERING – DATA EXCHANGE
FOR METER READING, TARIFF AND LOAD CONTROL –

Part 61: 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62056-61 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 with applicants throughout the world. In this respect, the
statement of the provider of the maintenance service is registered with the IEC. Information - see also 5.1 - may be

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 are capable of capturing, processing and
communicating this information to all parties involved.
For further analysis of this information, for the purposes of billing, load-, customer- and
contract management, it is necessary to uniquely identify all data in a manufacturer
independent way collected manually or automatically, via local or remote data exchange.
The definition of identification 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.

ELECTRICITY METERING – DATA EXCHANGE FOR
METER READING, TARIFF AND LOAD CONTROL –

Part 61: Object identification system (OBIS)

1 Scope
The OBject Identification System (OBIS) defines the identification codes (ID-codes) for
commonly used data items in electricity metering equipment. This part of IEC 62056 specifies
the overall structure of the identification system and the mapping of all data items 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 interface classes, or objects, as defined in
IEC 62056-62;
• data transmitted through communication lines, see clause A.1;
• data displayed on the metering equipment, see clause A.2.
This standard applies to all types of electricity 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 concept 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 13757-1:2002: Communication system for meters and remote reading of meters – Part 1: Data
exchange, published by CEN TC 294, "Communication systems for meters and remote reading meters" defines
identifiers for metering equipment other than electricity: heat cost allocators, cooling, heating, gas, cold water and
hot water.

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  302/02
Figure 1 – OBIS code structure
4.2 Value group A
The value group A defines the media (energy type) that the metering is related to. Non-media
related information is handled as abstract data.
4.3 Value group B
The value group B defines the 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
(e.g. in data concentrators, registration units). Data from different sources can thus be
identified. The definitions for this value group are independent from the value group A.

4.4 Value group C
The value group C defines the abstract or physical data items related to the information
source concerned, e.g. current, voltage, power, volume, temperature. The definitions depend
on the value of 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
The value group D defines types, or the result of the processing of physical quantities
identified with the 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
The value group E defines further processing or classification of quantities identified by value
groups A to D.
4.7 Value group F
The value group F defines the storage of data, identified by 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 specificcodes
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;
• Group D: 128…254;
• Group E: 128.254;
• Group F: 128…254;
If any of these value groups contain a value in the manufacturer specific range, then the
whole OBIS code shall be considered as manufacturer specific, and the value of the other
groups does not necessarily carry a meaning defined in this standard or in IEC 62056-62.
In addition, manufacturer specific ranges are defined in Table 14 with A = 0, C = 96 and Table
16 with A = 1, C = 96.
4.9 Reserved ranges

By default, all codes not allocated are reserved.
4.10 Summary of rules for manufacturer, utility, consortia and country specific codes
Table 1 summarises the rules for handling manufacturer specific codes defined in 4.8, utility
specific codes defined in 5.2, consortia specific codes defined in 5.4.3 and country specific
codes defined in 5.4.4.
