Summary:

I am debugging the KONNEX driver and am trying to determine how the Unit Address displayed relates to my Tag database or KNX address?

 

Solution:
The hex Unit Address corresponds to the Konnex Address x/y/z according to the following rule:
  • The lowest order 12 bits are unused
  • The next 8 bits correspond to Z - the group address
  • The next 3 bits correspond to Y - the sub group/middle number
  • The next 4 bits correspond to X - the main group number The next 5 bits are unused

e.g. an address of 0x01220000 is

0000 0001 0010 0010 0000 0000 0000 0000
            \---/\-/  \--------/
                 |      |            |
             X    Y         Z

                          

Unused
X = 0x2
Y = 0x2
Z = 0x20

Thus the Konnex address is 2/2/32
