ETHOS European Utilities

• In UK, France, Italy, and Denmark electricity
  meters will supply the same type of Information
• Tariff
• Economy-level
• Index, etc.

Heaters, Hot Water, Domestic Appliances can use
this information

Trialog EHS Road Map

• 1992 Trialog in EHS Components ESPRIT project
• 1994 Implementation of EHS lt 10 KB
• First EHS software on one microprocessor
• 1995 Decision to deliver the software as a
  library
• Development of a new library EHSLite
• Tests Environment, Certification
• 1996 Financial Investment and Products
• Complexity several Media, Micro,
  Standardisation,
• Convergence with EIB and BBus.

Trialog Libraries Approach

• Library tested on
• thousands of test cases
• ensures interoperability
• eases development
• short time to market
• ensures compatibility

Only the necessary part of the protocol is
included in a node
A library includes the FULL EHS Protocol
16
The Library Approach Avantages

• To address
• Technology dimensions
• Evolution of specification
• Interoperability and Conformance
• Reliability / Performance / Optimisation
• Trialog provides to Manufacturers
• EHS Technology Libraries, Tools, Support,
  Training
