Modbus TCP values filtering to KNX TP?

[Habib]

Hi,

today I have a question to my modbus connection.
I have 3 Modbus TCP Powermeters which I have successfully integrated in my spaceLYnk.
Now I get on each change a new value (4 Byte) for my visualisation. That's fine, but I don't need them in my KNX TP Netzwork, but the SL is sending them...

In first step I tried to filter them via IP>TP filter rules, but it doesn't work, so I tried it with TP>IP Filter (maybe I missunderstood the direction) but it doesn't matter also?

What I'm doing wrong, or is it impossible to make a filter between modbus TCP->KNX TP?

Happy new year

Hi Habib,

In modbus, click on configuration for on of you device and then click on one of the linked object.
You should see a checkbox: write on bus.
Is it check or not? try to change the status of the object and look if it's working as expected.

If not, maybe it's a bug.
I'll let @admin check this.

HNY to you too.

Yes, keep "Write to bus" unchecked and telegrams won't get sent to KNX/TP

Yes that was the solutions :-) thank you :-))
