Regarding the alarm & zone status updates to the KNX bus: it is essential that the UCM/KNX responds to status reads. I've noticed in large installations (>16 zones) that packet drops are possible, thus you cannot be certain if a zone is open or not (so as to show it on a KNX touchpanel). UCM/KNX has to be more frugal regarding the sending of bursts of packets on the KNX bus. Thus, if a KNX screen displays all zones on a floor it could query the bus for the zone status.
Responding to KNX READ request packets shouldn't be too hard to implement (if UCM/KNX has its own CPU and memory, why not?).
