block addresses within the logic machine itself - ALEJANDRO - 14.05.2026
It is possible to block group addresses within a logic machine; I don't mean blocking it from sending data to other logic machines, but rather preventing it from filtering these addresses itself. These addresses are values received by Modbus that are passed to KNX; they are standard, non-virtual addresses.

You should use Virtual objects instead.
A work around is to make sure to not select: wirte to bus in the mapping page.
This will block only writing to TP. To block writing to IP you must use KNX filter table and block these groups in the filter (Local to IP)

thanks,
Good morning,
I have a considerable number of standard group addresses. I now realize I should have made them virtual, but I can't change them at the moment.
I'm wondering if there's any way to prevent the logic machine from writing to these addresses; that is, I don't want it to write to the KNX bus (TP), because I've seen that this isn't possible in ETS6.
The reason is that these group addresses are not linked to any KNX device communication objects; they are empty.
