Communication between Logic Machine

[Daniel]

Good morning,

We have an installation where there are 7 areas to control connected by IP, I would like to know if it is possible to use different Logic Machine to control each of the rooms and connect them together so that one of them is the graphic and control interface and the others send the data to this. If possible, how would we pass the data between Logic Machines? Thank you very much. A greeting.

Hi

All LMs talk to each other by default via KNX IP(multicast).  Each LM will see each telegram from every line. You can filter telegrams by using filter table. 
There is other way to do it. You can use frame in main LM to display local visu in other LMs.  This would work better if you have lots of traffic.
