Inter...what?


• 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 the same way

• 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

Reaching interoperability: International standards and companion specifications

• International standards – specify what can be agreed on – specify only few mandatory elements – leave choices for flexibility – specify the semantics and the syntax of functions but not their details

• Companion specifications close interoperability gaps

– specify elements that must be present to support project use cases – make choices between options to optimize performance and costs – specify project specific elements (e.g. events) – specify processes for data exchange – should be jointly specified by project participants – Examples: Dutch DSMR, French Linky, Spanish T5, GBCS, Indian, Saudi

Arabian, Italian Gas, IDIS....

Companion spec. example - The IDIS project

• Initiative of Iskraemeco, Itron and Landis+Gyr

• learning from Dutch, French, Spanish projects

• Objective: create a market for interoperable meters with standard functions

• Companion specification to IEC 62056 DLMS/COSEM

• specifies details of the functions

• only selections made: nothing modified, nothing added

• IDIS interoperability test

• IDIS meters pass DLMS conformance test

• Publicly available, anybody can make IDIS meters

• Members committed to produce IDIS meters

• http://idis-association.com/


device


• Purpose: to verify correct implementation in meters (DLMS/COSEM servers)

• Protocol and object model tests • Helps product development

– Optional log module provides detailed, human readable information • Helps system integration • Self testing or third party testing • Accessible to any DLMS UA member

under fair and equal terms

Reaching interoperability: conformance testing
