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 interna-
tional 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, Techni-
cal 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 organiza-
tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-
ganization 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 inter-
ested 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 misinter-
pretation 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 be-
tween 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 equip-
ment 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 ex-
penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-
tions.
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. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example, "state of the art".
IEC 62051-1, which is a technical report, has been prepared by IEC technical committee 13:
Equipment for electrical energy measurement and load control.

The text of this technical report is based on the following documents:
Enquiry draft Report on voting
13/1299/DTR 13/1302/RVC
Full information on the voting for the approval of this technical report can be found in the re-
port on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of June 2005 have been included in this copy.

3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the following definitions, as well as those given in IEC
60050-714 and IEC 60050-716-1, apply.
3.1.1
3-layer, connection-oriented, HDLC-based profile (relevant to IEC 62056-46)
communication profile based on the OSI collapsed architecture, which consists of a physical
layer, a data link layer based on the HDLC standard and the COSEM application layer
containing the connection-oriented Application Control Service Element (ACSE)
3.1.2
abstract data and objects (relevant to IEC 62056-61 and IEC 62056-62)
data, other than measurement values, which may be related to an energy type and which are
modelled using abstract interface objects
3.1.3
ACTION (relevant to IEC 62056-53)
xDLMS data communication service used with logical name (LN) referencing for the
invocation of methods of COSEM interface objects. The availability of this service is indicated
in the xDLMS conformance block and its use is negotiated upon application association
establishment
– 6 – TR 62051-1 IEC:2004(E)
3.1.4
activation mask (relevant to IEC 62056-62)
element of the mask_list attribute of the COSEM interface class “Register activation”.
Activation masks define which “Register”, “Extended Register” and “Demand Register” objects
are enabled when an activation mask is active. Masks can be added to or deleted from the
mask list. At any time, only one mask is active
3.1.5
activity calendar (relevant to IEC 62056-62)
COSEM interface class used to model handling of different tariff structures. It defines
scheduled actions inside the meter, which follow the classical method of using calendar-
based schedules by defining seasons, weeks, etc. An “activity calendar” object may coexist
with the more general object “Schedule” and can even overlap with it
3.1.6
application association (AA) (relevant to IEC 62056-53 and IEC 62056-62)
logical connection between two application processes, defining the context of the information
exchange. In DLMS/COSEM, application associations are always established by the client
application process, using the COSEM-OPEN services. Application associations are identified
by lower layer addresses (SAP-s)
3.1.7
application association request (AARQ) (relevant to IEC 62056-53)
application protocol data unit (APDU) sent by the client application layer to the server
application layer, as a result of invoking the COSEM-OPEN.request service. It holds the
parameters defining the proposed application context and xDLMS context. It is carried by the
supporting layer
3.1.8
application association response (AARE) (relevant to IEC 62056-53)
application protocol data unit (APDU) which may be sent by the server application layer to the
client application layer proposing the association, as a result of invoking the COSEM-
OPEN.response service. It holds the parameters of the negotiated application context and
xDLMS context, or in case of failure, diagnostic information. It is carried by the supporting
layer
3.1.9
application context (relevant to IEC 62056-53)
common set of rules that govern the data exchange in a given application association.
In DLMS/COSEM, application contexts are pre-defined and they are identified by the
Application_Context_Name parameter of the COSEM-OPEN service
3.1.10
application control service element (ACSE) (relevant to IEC 62056-53)
service element of the application layer, controlling the establishment and release of
application associations
3.1.11
association LN (relevant to IEC 62056-62)
COSEM interface class used to model application associations between client and server
application processes when the server uses logical name (LN) referencing. A COSEM Logical
Device has one instance of this IC for each association the device is able to support. An
Association LN object holds the parameters of the application association context and the
xDLMS context, it provides a list of COSEM objects available within the given application
association together with access rights to their attributes and methods, and it handles the
authentication process (see also 3.1.12.)
TR 62051-1 IEC:2004(E) – 7 –
3.1.12
association SN (relevant to IEC 62056-62)
COSEM interface class used to model application associations between client and server
application processes when the server uses short name (SN) referencing. A COSEM Logical
Device has one instance of this IC for each association the device is able to support. An
Association SN object provides a list of COSEM objects available within the given association
and it has specific methods to provide inf
