EN 62056-62:2007

Electricity metering - Data exchange for meter reading, tariff and load control - Part 62: Interface classes

specifies a model of a meter as it is seen through its communication interface(s). Generic building blocks are defined using object-oriented methods, in the form of interface classes to model meters from simple up to very complex functionality.

This European Standard was approved by CENELEC on 2006-12-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,

Foreword
The text of document 13/1389/FDIS, future edition 2 of IEC 62056-62, prepared by IEC TC 13, Equipment
for electrical energy measurement and load control, was submitted to the IEC-CENELEC parallel vote
and was approved by CENELEC as EN 62056-62 on 2006-12-01.
This European Standard supersedes EN 62056-62:2002.
It includes the following significant technical changes with respect to EN 62056-62:2002:
– the list of common data types has been amended, some new types have been added;
– formatting for floating point numbers has been added;
– new HLS mechanisms have been added;
– instance specific data types have been replaced with a well-defined set of applicable data types;
– new units have been added;
– encoding of application_context_name and authentication_mechanism_name attributes of the
Association LN class has has been clarified;
– new interface classes “Register table” and “Status mapping” have been added;
– a new version of the “IEC local port setup”, “Modem configuration”, “Auto connect” and “HDLC setup”
interface classes have been added;
– new interface classes for setting up a TCP/IP based communication profile have been added.
References to related IETF RFCs and standards, as well as related definitions have been added;
– several amendments in Annex D “Relation to OBIS” have been made.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-09-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-12-01
with the EN have to be withdrawn
The International Electrotechnical Commission (IEC) and CENELEC draw attention to the fact that it is
claimed that compliance with this International Standard / European Standard may involve the use of a
maintenance service concerning the stack of protocols on which the present standard IEC 62056-62 /
EN 62056-62 is based.
The IEC and CENELEC take 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 with applicants throughout the world. In this
respect, the statement of the provider of the maintenance service is registered with the IEC. Information
