Electricity metering data exchange - The DLMS/COSEM suite - Part 6-1: Object Identification System (OBIS) (IEC 62056-6-1:2023)
EN IEC 62056-6-1:2024

This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS)
and the mapping of all commonly used data items in metering equipment to their identification
codes.
OBIS provides a unique identifier for all data within the metering equipment, including not only
measurement values, but also abstract values used for configuration or obtaining information
about the behaviour of the metering equipment. The ID codes defined in this document are used
for the identification of:
• logical names of the various instances of the ICs, or objects, as defined in
IEC 62056‑6‑2:2023;
• data transmitted through communication lines;
• data displayed on the metering equipment, see Clause A.2 in Annex A.
This document applies to all types of metering equipment, such as fully integrated meters,
modular meters, tariff attachments, data concentrators, etc.
To cover metering equipment measuring energy types other than electricity, combined metering
equipment measuring more than one type of energy or metering equipment with several physical
measurement channels, the concepts of medium and channels are introduced. This allows
meter data originating from different sources to be identified. While this document fully defines
the structure of the identification system for other media, the mapping of non-electrical energy
related data items to ID codes is completed separately.
NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators,
thermal energy, gas, cold water and hot water.

Electricity metering data exchange - The DLMS/COSEM suite - Part 8-12: Communication profile for Low Power Wide Area Networks (LPWAN) (IEC 62056-8-12:2023)
EN IEC 62056-8-12:2023

IEC 62056-8-12:2023 describes the use of DLMS®/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS®/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN.
This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN. Low-Power Wide Area Networks (LPWANs) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application-layer data sizes, and long battery life operation. This document does not provide functionality to manage the lower layers of the LPWANs.
This part of the DLMS®/COSEM suite specifies the communication profile for Low-Power Wide Area Networks (LPWANs).
The DLMS®/COSEM LPWAN communication profiles use connection-less transport layer based on the Internet Standard User Datagram Protocol (UDP) and Internet Protocol (IPv6).
The adaptation layer is based on IETF RFC 8724 which provides both a header compression/decompression mechanism and an optional fragmentation/reassembly mechanism. SCHC compression is based on static context with small context identifier to represent full IPv6/UDP/COSEM wrapper headers. If required, SCHC fragmentation is used to support IPv6 MTU over the LPWAN technologies.
This document follows the rules defined in IEC 62056-5-3:2023, Annex A, and in IEC 62056-1-0, and IEC TS 62056-1-1:2016 for its structure. See also Annex A for examples

This part of IEC 62056 specifies the DLMS®/COSEM application layer in terms of structure, services and protocols for DLMS®/COSEM clients and servers, and defines rules to specify the DLMS®/COSEM communication profiles.
It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface objects, defined in IEC 62056-6-2:2021 using either logical name (LN) or short name (SN) referencing.
Annex A (normative) defines how to use the COSEM application layer in various communication profiles. It specifies how various communication profiles can be constructed for exchanging data with metering equipment using the COSEM interface model, and what are the necessary elements to specify in each communication profile. The actual, media-specific communication profiles are specified in separate parts of the IEC 62056 series.

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 - 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.
