IEC 62056-8-4:2018 specifies DLMS/COSEM communication profiles for narrow-band OFDM power line carrier PRIME neighbourhood networks using the modulation as specified in Recommendation ITU-T G.9904:2012.
Three communication profiles are specified:
• a profile using the IEC 61334-4-32 LLC layer;
• a profile using TCP-UDP/IPv4;
• a profile using TCP-UDP/IPv6.

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 62056-8-4 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 using

Recommendation ITU-T G.9904:2012 Narrow-band orthogonal frequency division multiplexing

power line communication transceivers for PRIME networks. It applies for devices installed on

the neighbourhood network.

It follows the rules defined in IEC 62056-5-3:2017, Annex A, and in IEC 62056-1-0 and the

IEC TS 62056-1-1 recommendations for its structure.

The communication profile specified in this document is based on the results of the European

OPEN Meter project, Topic Energy 2008.7.1.1, Project no.: 226369, www.openmeter.com, and

has been prepared by the PRIME Alliance Technical Working Group, www.prime-alliance.org.

1 Scope

This part of IEC 62056 specifies DLMS/COSEM communication profiles for narrow-band

OFDM power line carrier PRIME neighbourhood networks using the modulation as specified in

Recommendation ITU-T G.9904:2012.
Three communication profiles are specified:
• a profile using the IEC 61334-4-32 LLC layer;
• a profile using TCP-UDP/IPv4;
• a profile using TCP-UDP/IPv6.
