Full title and description
St IEC 62056-53-2006 — Electricity metering — Data exchange for meter reading, tariff and load control — Part 53: COSEM application layer. Specifies the COSEM application layer in terms of structure, services and protocols for COSEM clients and servers and describes how to use the COSEM application layer in various communication profiles (services for establishing/releasing application associations, data communication services for accessing COSEM interface objects using Logical Name or Short Name referencing).
Abstract
This part of IEC 62056 defines the COSEM application layer (xDLMS/COSEM) used for meter data exchange. It specifies the structure of application protocol data units (APDUs), defines application services for association management and data access to COSEM objects (methods and attributes) and includes guidance and examples for using the application layer across different communication profiles. Annexes provide the xDLMS application service element, profile usage notes, APDU encoding examples and background on data models and protocols for meter data exchange.

Scope
The standard specifies the COSEM application layer used by DLMS/COSEM for utility metering data exchange. It covers structure and encoding of application protocol data units, services to establish and release application associations, and data communication services to access COSEM interface objects (attributes and methods) using either Logical Name (LN) or Short Name (SN) referencing. The scope includes guidance for using the application layer in defined communication profiles and illustrative encoding examples.
Key topics and requirements
- Definition of the COSEM application layer and APDU structures (xDLMS application service element).
- Services for establishing, maintaining and releasing application associations between COSEM clients and servers.
- Data communication services for reading and writing attributes and invoking methods on COSEM interface objects (LN and SN referencing).
- Specification of behaviour for COSEM clients and servers across multiple communication profiles (profile usage rules).
- Encoding rules and APDU examples for interoperability (annex with encoding examples).
- Guidance on the role of data models (COSEM interface classes) and protocols within meter data exchange ecosystems.
Typical use and users
Used by electricity (and other utility) meter manufacturers, firmware and protocol implementers, utility system integrators, smart meter solution vendors, test and conformance laboratories, and standards/technical committees. Typical activities include implementing COSEM application-layer stacks in meters and head-end systems, developing conformance tests, and integrating DLMS/COSEM-based metering into AMI/Smart Grid systems.
Related standards
Part of the IEC 62056 (DLMS/COSEM) suite. Closely related and commonly used together with IEC 62056-62 (COSEM interface classes / data model), IEC 62056-5-3 (which replaced this edition in 2013), IEC 62056-21 (optical/serial readout modes) and other IEC 62056 parts that define communication profiles, transport layers and conformance testing. DLMS User Association (DLMS/COSEM) specification documents (Blue/Green/Yellow Books) are also part of the ecosystem for implementation and conformance.

FAQ
Q: What is this standard?
A: IEC 62056-53:2006 defines the COSEM application layer used by DLMS/COSEM for exchanging metering data; it specifies APDU structures, application services and how to access COSEM interface objects.
Q: What does it cover?
A: It covers application-layer structures and services (association management, data access to attributes/methods), encoding and APDU examples, and guidance on using the COSEM application layer across communication profiles; it references the COSEM object model defined in IEC 62056-62.
Q: Who typically uses it?
A: Meter manufacturers, firmware developers, head-end system integrators, test laboratories, utilities and standards bodies involved in implementing or testing DLMS/COSEM-based metering solutions.
Q: Is it current or superseded?
A: It is superseded. IEC 62056-53:2006 was withdrawn (withdrawal effective 5 June 2013) and replaced by IEC 62056-5-3:2013 (the newer part consolidates and updates application-layer specifications).
Q: Is it part of a series?
A: Yes — it is one part of the IEC 62056 series (the DLMS/COSEM suite) that together define data models, communication profiles, transport and conformance testing for meter data exchange.
