Hi,

I'me writing some software to directly control EIB output actuators (4-8 actuators per device). I know I can use the physical address to send a telegram to a specific device. My question is: is it possible to use the physical address to set an individual output on the KNX Device?

I realise this is normally handled locally by the KNX device using groups, but I have a limitation due to the number of devices and the number of groups I have available.

Thanks,

shark

In my opinion it is impossible. You are using as destination: group address (funtion) or physical address (f.e. to commision device). There is DAF flag in telegram, which determines kind of telegram.

As I know physical messeging is not the operational mode in KNX. Physical messaging is uded only during commissiong but not used (or maybe recommended) in operating mode.

Thanks for the responses Gents. I suspected as much, but was hoping that someone knew of another method! As each output needs to be controlled individually, I'll have to drop every single output into a unique group (we're designing up to 50 devices on a KNX segment - so lot's of groups!).
