3. Terms, definitions and abbreviations
3.1 Terms and definitions
For the purpose of data exchange with metering equipment, using DLMS/COSEM, the following
definitions apply:
3.1.1
3-layer, connection-oriented, HDLC based profile [IEC 62056-46]
A 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 contain-
ing the connection-oriented Application Control Service Element (ACSE).
3.1.2
Abstract data and objects [IEC 62056-61] [IEC 62056-62]
Abstract data are data other than measurement values. They may be related to an energy type.
Abstract data are modelled using abstract interface objects.
3.1.3
ACTION [IEC 62056-53]
An xDLMS data communication service used with logical name (LN) referencing for the invoc a-
tion 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 as sociation establish-
ment.
3.1.4
Activation mask [IEC 62056-62]
An element of the mask_list attribute of the COSEM interface class Register activation. Acti-
vation 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 ac tive.
3.1.5
Activity calendar [IEC 62056-62]
A COSEM interface class used to model handling of different tariff structures. It defines sched-
uled actions inside the meter, which follow the classical way of calendar based schedules by
defining seasons, weeks etc. An Activity calendar object may coexist with the more general
object Schedule and it can even overlap with it.
3.1.6
Application association (AA) [IEC 62056-53] [IEC 62056-62]
A logical connection between two application processes, defining the context of the information
ex change. In DLMS/COSEM, application associations are always established by the client ap-
plication process, using the COSEM-OPEN services. Application associations are identified by
lower layer addresses (SAP-s). DLMS User Association, Glossary of Terms, First Edition

3.1.7
Application Association Request (AARQ) [IEC 62056-53]
An application protocol data unit (APDU) sent by the client application layer to the server ap-
plication layer, as a result of invoking the COSEM-OPEN.request service. It holds the parame-
ters defining the proposed application context and xDLMS context. It is carried by the support -
ing layer.
3.1.8
Application Association Response (AARE) [IEC 62056-53]
An 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 [IEC 62056-53]
A common set of rules that govern the data exchange in a given application association. In
DLMS/COSEM, appl
