ETS = the unique, common tool for the design, configuration and servicing of KNX sites.

• The ETS tool suite is vendor /

manufacturer-independent.

– User imports “Product Libraries” from any

desired manufacturers.

• A toolkit for product manufacturers

supports product testing and creation of

Product Libraries.

• The ETS end-user edition now comes in 2

versions:

– ETS 3 Starter – entry level / single-home

projects = 149,- €

– ETS 3 Professional – full edition – 895, - €

The building blocks for KNX Application Interworking.

• The KNX specification essentially fixes:

– The “atoms” of interworking: Datapoint TypesDatapoint Types

– The “molecules” of interworking: Functional BlocksFunctional Blocks

= a grouping of typed datapoints, representing the operational interface (with inputs and outputs) of one instance (“channel”) of a function.

– The “organisms” of interworking:
