Electricity metering - Payment systems - Part 31: Particular requirements - Static payment meters for active energy (classes 0,5, 1 and 2)
EN IEC 62055-31:2022

This part of IEC 62055 applies to newly manufactured, static watt-hour payment meters of
accuracy classes 0,5, 1 and 2 for direct connection, for the measurement of alternating current
electrical energy consumption of a frequency in the range 45 Hz to 65 Hz that include a supply
control switch for the purpose of interruption or restoration of the electricity supply to the load
in accordance with the current value of the available credit maintained in the payment meter. It
does not apply to static watt-hour payment meters where the voltage across the connection
terminals exceeds 1 000 V (line-to-line voltage for meters for polyphase systems).
It applies to payment meters for indoor application, operating under normal climatic conditions
where the payment meter is mounted as for normal service (i.e. together with a specified
matching socket where applicable).
Payment meters are implementations where all the main functional elements are incorporated
in a single enclosure, together with any specified matching socket. There are also multi-device
payment metering installations where the various main functional elements, such as the
measuring element, the user interface unit, token carrier interface, and the supply control switch
are implemented in more than one enclosure, involving additional interfaces.
Functional requirements that apply to payment meters are also defined in this document, and
include informative basic functional requirements and tests for the prepayment mode of
operation in Annex A. Allowances are made for the relatively wide range of features, options,
alternatives, and implementations that may be found in practice. The diverse nature and
functionality of payment meters prevent the comprehensive specification of detailed test
methods for all of these requirements. However, in this case, the requirements are stated in
such a way that tests can then be formulated to respect and validate the specific functionality
of the payment meter being tested.
This document does not cover specific functionality or performance requirements for circuit
protection, isolation or similar purposes that may be specified through reference to other
specifications or standards. Safety requirements removed from Edition 1.0 have been replaced
with references to the safety requirements now contained in IEC 62052-31:2015, the product
safety standard for newly manufactured electricity meters. In-service safety testing (ISST) is
not covered by IEC 62052-31:2015 and is left to national best practice usually as an extension
of existing in-service testing (IST) of metrology stability.
This document does not cover software requirements. This document covers type-testing
requirements only. For acceptance testing, the requirements given in IEC 62058‑11:2008 and
IEC 62058-31:2008 may be used.
Dependability aspects are addressed in the IEC 62059 series of standards. Additional reliability,
availability, maintenance and life cycle aspects are provided by IEC TC 56.

Electricity metering - Payment systems - Part 42: Transaction Reference Numbers (TRN)
EN IEC 62055-42:2022

This document specifies a token generation mechanism and token structure for smart
prepayment functionality in markets where IEC 62055-41 compliant systems are not used, and
where a different security mechanism is required by project-specific or national requirements.
This document specifies token structure, authentication and an anti-replay mechanism, token
operating model, and protocol.
This document is informed by the STS Association key management services, and by the key
management mechanisms used within the DLMS/COSEM security model within IEC 62056‑6‑2.
Reference is made to the international STS token standards (IEC 62055-41, IEC 62055-51 and
IEC 62055-52) for payment metering systems, and interworking has been considered where
appropriate in terms of token carrier ranges in the decimal domain. IEC 62055-41 tokens and
those described in this document are not interoperable, however their domains are designed to
be mutually exclusive to ensure the two kinds of tokens do not interfere with each other.
Metering application processing and functionality, HAN interface commands and attributes,
WAN interface commands and attributes are outside the scope of this document; however,
reference is made to other standards in this regard.
The mechanism for auditing and retrieving data from the meter relating to tariffication, meter
readings, profile data and other legal metrology information is outside the scope of this
document; however, this is defined as part of any overall metering solution. Such interfaces for
retrieving data from a meter may be defined using suitable protocols such as DLMS/COSEM as
defined in the IEC 62056 series.

Electricity metering data exchange - The DLMS/COSEM suite - Part 3-1: Use of local area networks on twisted pair with carrier signalling
EN IEC 62056-3-1:2021

This part of IEC 62056 describes two sets of profiles: the first set of profiles allows a
bidirectional communication between a client and a server. This set of profiles is made of three
profiles allowing local bus data exchange with stations either energized or not. For nonenergized
stations, the bus supplies energy for data exchange. Three different profiles are
supported:
• base profile: this three-layer profile provides remote communication services;
NOTE 1 This first profile was published in IEC 61142:1993 and became known as the Euridis standard.
• profile with DLMS: this profile allows using DLMS services as specified in IEC 61334-4-41;
NOTE 2 This second profile was published in IEC 62056-31:1999.
• profile with DLMS/COSEM: this profile allows using the DLMS/COSEM Application layer and
the COSEM object model as specified in IEC 62056-5-3 and in IEC 62056-6-2 respectively.
The three profiles use the same physical layer and they are fully compatible, meaning that
devices implementing any of these profiles can be operated on the same bus. The transmission
medium is twisted pair using carrier signalling and it is known as the Euridis Bus.
The second set of profiles allows unidirectional communication between a given Energy
Metering device and a Customer Energy Management System. This second set is made up of
three profiles.
Subclause 4.2.1 to Clause 8 included specify the bidirectional communication using twisted pair
signalling and Clause 9 to 9.5 the unidirectional communication using twisted pair signalling.
