THE

STANDARD OF CHOICE FOR SMART METER DATA EXCHANGE

Energy metering has been deeply transformed by new energy policies, market environments and technologies. The new, smart generation of meters handle not only energy but also data flows supporting a wide range of business and operational processes and functions. Smart meters play a key role in operating energy markets and improving efficiency by providing suppliers and users with energy information. Deployed in large numbers they change the way energy is generated, distributed and used. Well specified, widely accepted standards are essential in building efficient, interoperable metering systems. DLMS/COSEM meets the need for such standards. The DLMS/COSEM standardization framework is based on the principle of one common data model and application layer, used over a range of communication media. This principle reflects the fact that the data model standards are driven by the use cases while data communication standards are driven by technology evolution. DLMS/COSEM specifies the COSEM data model, the DLMS application layer protocol and communication profiles. It continuously evolves to meet new requirements. It is the only global standard for meter data exchange adopted by global, regional and national standards organizations.

The Blue Book Specifies the functional data model of the meter as seen through its interfaces. Using the object oriented approach, it specifies COSEM objects that interact with each other to realize the functions required. The objects – and the data they hold – are identified by the OBIS codes.

The Green Book Specifies how to access data and how to transport the resulting messages over the communication media. DLMS application layer services allow establishing secure associations between applications running in meters and central systems, and accessing COSEM objects to read / write data and execute actions re-motely. Pull and push operation is supported. The Green Book also specifies how application data and messages are protected using cryptographic algorithms. Communication profiles specify how DLMS/COSEM is used over various communication channels and media. Lower protocol layers use widely accepted international standards.

The Yellow Book Specifies abstract conformance test plans and the testing and certification process.

The White Book Contains a glossary of terms that help understanding the specification.

Key characteristics DLMS/COSEM has been conceived to model advanced metering and control functions for all energy types in all market segments and to exchange metering data over all communication media. Specific COSEM objects – currently some 50 different interface classes – are available to hold individual measurement and configuration data or groups of such data, to control functions based on time or events, to control access to data, to manage the meter, its security functions and its communication interfaces. The various kinds of COSEM objects can be used the same way for metering and controlling electrical, gas, water, heat energy and more. The OBIS codes are energy type specific to reflect the differences in physical quantities and the way they are processed. With the COSEM model a large range of metering and control functions, like billing, load profiling, power quality measurement, revenue protection, customer information, load and supply control can be modelled. Management functions include configuration, parametrization, firmware update, security, meter and communication channel supervision.

Evolutive Standard extension mechanisms are available that facilitate adding new features while maintaining backward compatibility. The COSEM model, the DLMS services and the communication profiles can be extended independently.

Flexible The standard elements can be freely combined to tailor the system to the target application.

Interoperable The self-descriptive COSEM object model, negotiation of the features implemented, standard identifiers and data types ensure interoperability between products of different vendors. Companion specifications specify choices where these are provided to close any interoperability gaps.

Secure end-to-end Advanced data access and data transport security features based on proven cryptographic standards ensure end-to-end security between systems of market participants and the meter through the metering head end system.

Efficient Data organization tools, efficient encoding as well as adaptation to communication channel characteristics ensure low overhead and efficient data exchange.

INTERNATIONAL

STANDARDIZATION AND COMPLIANCE CERTIFICATION IEC

International standardization and certification of compliance to the standard are key elements of the activities of the DLMS UA. The development and maintenance of the DLMS/COSEM specification takes place in working groups bringing together the best experts in the industry. Market requirements and use cases are analysed and mapped to COSEM interface classes, OBIS codes, protocols and test procedures. The contents of the Coloured Books are offered to international and regional standards organizations. The DLMS UA has developed and operates a compliance certification process in cooperation with the company EuroDCS GmbH. The abstract test plans are specified by the DLMS UA. The Conformance Test Tool is available for members through EuroDCS GmbH. Test reports are verified and Certificates are issued by the DLMS UA.

DLMS/COSEM was adopted in 2002 by the IEC as the IEC 62056 suite for electricity metering. The second edition was published in 2006 and the third edition in 2013. The DLMS UA is liaised with IEC TC 13 WG 14 and acts as the registration authority.

CEN DLMS/COSEM was adopted in 2002 by CEN as part of the EN 13757 suite for metering energy types other than electricity. A second edition was published in 2013. The DLMS UA is liaised with CEN TC 294 and acts as the registration authority.

CENELEC DLMS/COSEM is the basis of developing new communication profiles using power line carrier by CENELEC TC 13 WG 02 under the smart metering standardization mandate M/441. The DLMS UA is a Technical Liaison Partner of CENELEC.
