• 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

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

DLMS/COSEM: The standard of first choice
 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
…in metering, we speak the same language
