Hello!
I have used in past KNX MDT IP Router to communicate with Beckhoff PLC. So I have custom made Beckhoff UDP library.
Now I'm trying to use LogicMachine instead of MDT IP Router. Tested today and data receiving will not work.
I tried all kind of modes (TP, IP Routing etc) but no luck. Sending is working from Beckhoff side to KNX (to LM -> KNX TP).
Doesn't matter if some device sends packet to KNX TP line or I create group address from LM and edit value - I don't even see that something is received (to Beckhoff).
Does someone have any clue what can cause that?
Using KNX default multicast address: 224.0.23.12 and port 3671
Beckhoff IP: 192.168.132.22
LogicMacine IP: 192.168.132.20
KNX IP Feature is enabled.
I attach image where is seen my UDP data packets on sending side. Also I receive the same data what I send, so my Beckhoff UDP receive library works. Routing counter is 5 so it has passed one router (LogicMachine).
I have feeling that LM can receive UDP packets but can't send...
