Full title and description

IEC 62056-62:2006 — Electricity metering — Data exchange for meter reading, tariff and load control — Part 62: Interface classes. Specifies an object-oriented model of a meter presented via its communication interfaces (the COSEM/ DLMS object model), defining generic interface classes and common data types used for meter data exchange.

Abstract

This standard defines the COSEM interface classes used to model meter functionality (registers, profiles, clocks, schedules, associations, utility tables, etc.), data formats, common data types and basic authentication/association concepts so that metering devices and systems from different vendors can interoperate for meter reading, tariff management and load control. The 2006 edition is the second edition of Part 62.

Scope

IEC 62056-62:2006 specifies a model of an electricity meter as exposed through its communication interfaces using COSEM interface classes. It defines the class descriptions and attribute/method semantics, common data types and formats (including date/time and numeric encodings), the COSEM server model and basic authentication/association procedures used for meter reading, tariff and load control applications. The standard is part of the DLMS/COSEM suite used for interoperable meter communications.

Key topics and requirements

• Definition of COSEM interface classes (Data, Register, Extended Register, Demand Register, Profile Generic, Clock, Schedule, Activity Calendar, Association LN/SN, etc.).
• Common data types and data formats for attributes and methods (incl. date/time, numeric encodings and units).
• COSEM server model and logical device/association concepts for secure access and authentication.
• Relationship and mapping to OBIS (object identification) and to other DLMS/COSEM parts (application and transport layers).
• Maintenance rules for interface classes (adding/removing classes, versioning).

Typical use and users

Used by electricity meter manufacturers, firmware and communications protocol engineers, utility system integrators, smart metering solution providers, certification and test laboratories, and standards/implementation bodies (e.g., DLMS User Association) implementing DLMS/COSEM-based metering and data-collection solutions. It serves as a normative reference when designing meter object models and implementing meter communication stacks.

FAQ

Q: What is this standard?

A: IEC 62056-62:2006 is the part of the IEC 62056 suite that defines COSEM interface classes — the object-oriented model and class definitions that represent meter functionality for meter reading, tariff and load control.

Q: What does it cover?

A: It covers the definition and semantics of interface classes (attributes, methods, data types), data formats, the COSEM server model, and basic association/authentication mechanisms used in DLMS/COSEM communications.

Q: Who typically uses it?

A: Meter manufacturers, firmware developers, utility integration teams, test laboratories and organisations implementing DLMS/COSEM for automated meter reading and smart-grid applications.

Q: Is it current or superseded?

A: The 2006 Part 62 edition has been superseded — the COSEM interface-classes work has been restructured and published under IEC 62056-6-2 (2013 and later editions/EN/IEC replacements). The IEC webstore records the 2006 Part 62 publication as replaced by IEC 62056-6-2:2013 (withdrawal date listed). Implementers should use the current IEC/EN IEC 62056-6-2 edition appropriate for their region.

Q: Is it part of a series?

A: Yes — it is one part of the IEC 62056 series (the DLMS/COSEM suite) which includes parts for application layer, transport layers, OBIS (object identification), and other protocol/physical-layer specifications used together for interoperable meter communications.

Q: What are the key keywords?

A: COSEM, DLMS, interface classes, OBIS, meter data exchange, smart metering, profile generic, register, schedule, authentication.
