The idea is ether to add fields that can't be edited that display 2 and Free styles for 3-level address or to show in the editable parameter for KNX IP Router -> Group Address Styles.
|3-Level;||2/2/2 = 00010/010/00000010b|
|2-Level;||2/514 = 00010/010 00000010b|
|Free-Level;||4610 = 00010 010 00000010b|
A project can be switched between levels 2 and 3 in ETS. But if it is FREE, one has to think that 2/2/2 has to be sent to 4610 address.
