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. Regards |

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!). |
