Electricity metering data exchange - The DLMS/COSEM suite - Part 5-3: DLMS/COSEM application layer (IEC 62056-5-3:2013); English version EN 62056-5-3:2014
Datenkommunikation der elektrischen Energiemessung - DLMS/COSEM - Teil 5-3: DLMS/COSEM-Anwendungsschicht (IEC 62056-5-3:2013); Englische Fassung EN 62056-5-3:2014
Overview
This standard specifies the DLMS/COSEM application layer in terms of structure, services and protocols for COSEM clients and servers, and defines how to use the DLMS/COSEM application layer in various communication profiles. It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface objects, defined in IEC 62056-6-21, using either logical name (LN) or short name (SN) referencing. Annex A (normative) defines how to use the COSEM application layer in various communication profiles. It specifies how various communication profiles can be constructed for exchanging data with metering equipment using the COSEM interface model, and what are the necessary elements to specify in each communication profile. The actual, media-specific communication profiles are specified in separate parts of the IEC 62056 series. The responsible committee is DKE/K 461 "Elektrizitätszähler" ("Electricity meters") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
