Two Logic Machine in Project

[imprashant]

Hi I have a KNX project in which there are three areas, each area has 8 Lines and in each line we are using KNX IP Router as Line coupler.
Now we need to Control and Monitor all three areas and create a GUI for same.
Could you please guide me how many LM5 we have to use in this project and there placement in KNX topology.
Sharing with you the topology we have created.

Hi, how many group addresses per area? Are you going to pass all to LM or only some? What else is LM going to do apart of GUI?

Total group address per area is around 1200, apart from GUI there will be time scheduling, some logical scripting also we have to send data to BMS system over BACnet.

I would use one per area and this would dance nicely. You could try with one but it would depend on the other load you mentioned.If the traffic will be high this also might affect it. They should be placed on the IP side and set KNX mode to IP routing.
