Electricity metering data exchange – The DLMS/COSEM suite – Part 7-5: Local data transmission profiles for Local Networks (LN) - Edition 1.0
 N 62056-7-5

Annotation

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.
