The Europeans voted in 2003 to approve BACnet as a European standard within CEN, the Committee for European Standardization. EIB, Batibus and EHS are being "converged" into a new standard called Konnex. Importantly, CEN has now concluded that the various protocols should no longer be rigidly associated with any particular level - any protocol may now be used to carry out the functional requirements of any level as desired. This is good for BACnet which has always been capable of being used from "top to bottom"!
