Standard KNX Group Addresses
Standard KNX group addresses are used to communicate with real KNX devices connected to the KNX bus. These devices must be properly configured and commissioned using ETS.
Format
A standard KNX group address is a 16-bit integer, represented in the format:
a/b/c – where each part is a decimal number separated by slashes:
|
Size (bits) |
Range |

|---|---|---|
|
a |
5 |
0 – 31 |
|
b |
3 |
0 – 7 |
|
c |
8 |
0 – 255 |
The address 0/0/0 is not allowed.
However, addresses with zeroes in one or two components are valid, such as:
-
0/0/1
-
2/0/0
-
0/3/0
-
0/4/5
-

Total possible addresses: 65 535 (32 * 8 * 256 – 1 = 65 535)
