List of standard OBIS codes and COSEM objects

Documents listing standard COSEM objects

These documents contain the list of standard COSEM objects.

Each COSEM object is identified by its logical name given by OBIS, class identifier and version. The interface class definitions also specify the data types to be used for each attribute. In some cases, a choice between data types is allowed.

The document DLMS UA 1001-6 “COSEM conformance testing – List of standardised OBIS codes” lists valid combinations of logical names / OBIS codes and interface class(es).

The documents DLMS UA 1001-7 “COSEM conformance testing – Object definition tables” lists valid combinations of logical names / OBIS codes and interface class(es), as well as the data types allowed where a choice of data types for value attributes is allowed.

The documents are regularly maintained to accommodate new COSEM object definitions. Newer versions are upper compatible with older ones therefore the older versions remain valid.

These documents are used by the DLMS/COSEM Conformance Test Tool to test the COSEM objects implemented in meters. For this purpose, the documents are translated to .dat files.

From DLMS UA 1001-6, .dat files are generated for use with CTT V1.x.

From DLMS UA 1001-7, .dat files are generated for use with CTT V1.x and with CTT V2. From version 1.7, .dat files are only generated for use with CTT V2.

The .dat files can be downloaded by licensed users of the CTT from the following link: http://www.eurodcs.com/.

The following table lists the documents currently valid:
