FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
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 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 chapter 5.1)
may be obtained from:
DLMS User Association
Geneva / Switzerland
www.dlms.ch
The IEC takes no position concerning the evidence, validity and scope of this maintenance service.
International Standard IEC 62056-61 has been prepared by IEC technical committee 13: Equip-

ment for electrical energy measurement and load control.
The text of this standard is based on the following documents:
FDIS Report on voting
13/1269/FDIS 13/1275/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

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 –
