DLMS/COSEM Vocabulary

• DLMS, “Device Language Message Specification” – COSEM object related messaging services – evolution from DLMS “Distribution Line Message Specification”:

• DLMS IEC 61334-4-41 by IEC TC57) >> • xDLMS (IEC 62056 by IEC TC13)

– DLMS provides the syntax of the message exchange • COSEM, “Companion Specification for Energy Metering”

– object model of meter functions as seen through its interfaces • OBIS, “Object Identification System”

– naming system of the objects – COSEM and OBIS provide the semantics of the application

• DLMS/COSEM – comprises the model, the application layer protocol and the

communication profiles

• Data model, to view the meter functionality at its interface(s) • COSEM objects • OBIS Object Identification System

• Messaging method to communicate with the model and to represent data as a series of bytes (APDUs)

• Transportation method to carry the messages over the media between the meter and remote parties

Separation of model and protocol: “orthogonality”

DLMS/COSEM is OPEN

Specification is – freely available for DLMS UA members – internationally standardised: IEC, CENELEC, CEN – free of IP rights on any parts of the standards – the basis of several project-specific companion specifications

DLMS UA membership is open to anybody at nominal fee – participation in technical work – training and technical support – conformance test tool is available at equal and fair terms – forum for exchanging best practices

DLMS/COSEM is MANAGEABLE (ITU-T X.700 FCAPS classification)

Performance • selective access to large data • with-list requests for multiple data • compact encoding, templates,

compression • pull and push operation • negotiation of comm. parameters

Configuration • active / passive parameter sets • parameter monitoring and logs • image transfer and activation • negotiation of contexts and capabilities

Security • peer authentication, access rights • end-to-end, multi-layer protection of messages and data • security suites, security policies, key management • security logs

Fault management • alarms and alarm monitors • diagnostic information • error logs • event notification

Accounting • client user white listing and log • event logs • parameter logs


device


DLMS/COSEM is INTEROPERABLE

• Interconnectivity: all, what has to be connected, can be connected (physical and abstract level)

• Interoperability: ability of diverse systems to work together – syntactic: ability to exchange data - protocols, formats – semantic: data exchange produces (agreed) useful results

• Interchangeability: elements providing the same function

• Reaching true interoperability – open international standards – partnership and co-operation – discipline in following the standard – conformance testing – companion specifications make the choice between options, and specify project

specific elements that cannot be specified internationally – project specific interoperability testing


device


DLMS/COSEM: The standard of first choice

…in metering, we speak the same language

Data models, messaging methods and protocols with enhanced security, for meter data exchange

Multi-utility and multi-media Self-descriptive, negotiable features Efficient data organization and access Meters of any complexity, from standard building blocks Covers smart metering use cases Balance between flexibility and overhead Open, international standard, widely supported Supports innovation and competition Future proof Testable interoperability
