Part 7-5: Local data transmission profiles for Local Networks (LN)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this International Standard may involve the use of a maintenance service concerning the stack of protocols on
which the present standard IEC 62056-7-5 is based.
The IEC takes no position concerning the evidence, validity and scope of this maintenance service.
The provider of the maintenance service has assured the IEC that he is willing to provide services under
reasonable and non-discriminatory terms and conditions for applicants throughout the world. In this respect, the
statement of the provider of the maintenance service is registered with the IEC. Information may be obtained from:

INTRODUCTION
As defined in IEC 62056-1-0, the IEC 62056 DLMS/COSEM suite provides specific
communication profile standards for communication media relevant for smart metering.
Such communication profile standards specify how the COSEM data model and the
DLMS/COSEM application layer can be used on the lower, communication media-specific
protocol layers.
Communication profile standards refer to communication standards that are part of the
IEC 62056 DLMS/COSEM suite or to any other open communication standard.
This International Standard specifies DLMS/COSEM communication profiles for transmitting
metering data modelled by COSEM interface objects through Local Data Transmission
Interfaces (LDTI). The LDTI may be part of a meter or of a Local Network Access Point
(LNAP) hosting a DLMS/COSEM server.
The specification of the communication profiles follows the rules defined in
IEC 62056-5-3:2016, Annex A.
A major driver for the introduction of smart metering is to provide the consumer with suitable
metering information to optimise his/her energy consumption and/or production. For that
purpose, smart meters are equipped with local interfaces providing metering data for the
consumer on consumer devices.
IEC 62056-21 and IEC 62056-3-1 are communication standards that specify direct local data
exchange and data exchange through local networks. They provide protocol modes that
support the DLMS/COSEM application layer and thus the COSEM object model. They also
specify legacy modes that do not support the DLMS/COSEM application layer.
In order to allow connecting legacy consumer equipment to the LDTI, this International
Standard also specifies communication profiles using protocol modes that do not support the
DLMS/COSEM application layer.
It is assumed, however, that in all cases the metering application is modelled by COSEM
interface objects.
It is also assumed that the meter has interfaces that fully support DLMS/COSEM and allow
the configuration of the local data transmission interface by a DLMS/COSEM client.
The requirements on the physical type of the interface, the choice of the data transmitted and
the transmitting pattern highly depends on the markets and projects the meter is designed for.

Part 7-5: Local data transmission profiles for Local Networks (LN)



1 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
