BACnet and EIB/Konnex make intelligent partners


I read Peter Manolescue's article on the benefits of the intelligent, integrated building (AJ 20.2.03) with interest. My company, Andromeda Telematics, is already delivering such buildings using the EIB/Konnex protocol. I have to disagree with Manolescue's point regarding LonWorks, BACnet and Konnex, that they are incompatible.

On 18 January, BACnet was approved as an ISO standard and BACnet states on its website that addendum D to the BACnet protocol 'describes how to interconnect BACnet devices with devices that use the EIB/Konnex protocol'. In Europe there is a large installed base of EIB/Konnex products and defining a way to interconnect Konnex and BACnet devices was one of the keys to the recent adoption of BACnet as an ISO standard.

In fact, BACnet and EIB/Konnex are a natural fit, both using an object-oriented approach that makes passing data a breeze, and both being complementary in that BACnet handles the BMS and Automation layers while EIB/Konnex functions at the floor layer.
