IEC 62056-5-3:2016

IEC 620565-3:2013 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 62056-6-2, using either logical name (LN) or short name (SN) referencing. This edition cancels and replaces IEC 62056-53 published in 2006. It constitutes a technical revision.

IEC 62056-5-3:2017 specifies the DLMS/COSEM application layer in terms of structure, services and protocols for DLMS/COSEM clients and servers, and defines rules to specify the DLMS/COSEM 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 62056-6-2 using either logical name (LN) or short name (SN) referencing. This third edition cancels and replaces the second edition of IEC 62056-5-3, published in 2016. It constitutes a technical revision.
