Hello guys i need your help i have a building with 4 ip routers and 1 Lm the routers have ip 192.168.7.x and logic machine has ip 171.16.1.x and when i move the Lm
in the 192.168.7. subnet i get to many telegrams reapets and i checked the error logs and i found high temprature alert. When i turn on and off a light lm made it many times.

Please draw some architecture to show how everything is connected.

What about TP connection? Is LM connected to the same TP line as one of the routers?

In such architecture LM should be connected only to IP and routers should have filter table for groups which LM should see.
If you want to keep TP connected then change LM multicast an then LM will only see telegrams from TP but not IP.

Your previous network configuration is wrong: 171.16.1.x is public IP range, private range is 172.16.1.x

Do as Daniel suggested. You have created a loop between TP and IP when LM and IP Router were connected to the same TP line.

so do you think that the mode, in the Logic Machine, at the setting 'KNX connection" is wrong?
We have set it to TP-UART. should we change it to IP Routing?
what settinngs do you suggest we should use to avoid repetitions?
thank you once more for your help

If you switch to IP routing then all will be fine.

Or remove IP router 7.11 as LM is functioning as it.. saves you 1 device (:

hello guys,
i tried all your suggestions.
As a result both worked.
First we tried with the same hardware setup and disabled the multicast, changed mode to IP Routing, and changed the ip address of the logic machine to 192.168.7.10 . everything fine and normal operation and telegrams.
Secondly we removed the first IP router (192.168.7.11), we enabled multicast with mode TP-UART, and everything runs smoothly as above.
thank you for your help once more.
