scope:

This part of IEC 62056 specifies DLMS/COSEM communication profiles for transmitting metering data modelled by COSEM interface objects through a Local Data Transmission Interface (LDTI). The LDTI may be part of a meter or of a Local Network Access Point (LNAP) hosting a DLMS/COSEM server.

The main body of this standard specifies the common aspects of the different communication profiles for the LDTI interface.

The Annexes specify the communication protocol specific elements. The Annexes form an integral part of this International Standard.

Annex A (normative) specifies a communication profile using the protocol specified in IEC 62056-21. Clause A.1 specifies the communication profile that supports the DLMS/COSEM application layer and Clause A.2 specifies the communication profile using the legacy Mode D. The physical interface is the optical interface specified in IEC 62056-21:2002, 4.3.

Annex B (normative) specifies a communication profile using the protocol specified in IEC 62056-3-1. Clause B.1 specifies the communication profile that supports the DLMS/COSEM application layer and Clause B.2 specifies the communication profile using the legacy mode. The physical interface is twisted pair using carrier signalling known as the Euridis Bus.

Annex C (normative) specifies a communication profile based on the DLMS/COSEM 3-layer, connection oriented HDLC based profile specified in IEC 62056-7-6. The physical interface is RS 485 or TIA-232-F.

Annex D (normative) specifies a communication profile using the physical layer specified in EN 13757-2 and the HDLC based data link layer specified in IEC 62056-46. The physical interface is twisted pair with baseband signalling.

Annex E (normative) species a communication profile using UDP/IP. The physical layer is out of the scope of this International Standard.

The communication profiles in Clauses A.1, B.1, and Annexes C, D and E support the DLMS/COSEM application layer.

Annex F (informative) specifies an LDTI configuration example.

Annex G (informative) provides encoding examples. Additional communication profiles for other media/communication protocols may be added in the future.

The scope of these communication profiles is restricted to aspects concerning the use of communication protocols in conjunction with the DLMS/COSEM data models. Data structures specific to a communication protocol should be defined in the specific protocol standards. Any project specific definitions of data structures and data contents shall be provided in project specific companion specifications.
