BACnet Gateway

[Diggerz]

Thanks, I'll stick with using the same multi cast address for the entire network and be selective with the objects we pass through the ip routers. Would there be any issue with using the logic machine as one of the 7 ip routers for a KNX line as well as providing BACnet, visuals etc for the floor. So 6 ip routers and 1 LM, or would it be better to use 7 ip routers and set the LM aside to perform just the BACnet, and visuals only for each floor?  

I'm planning to structure the project as 1 main line per floor, each with 7 sub lines. so 1.1.x -- 1.7.x, 2.1.x -- 2.7.x, 3.1.x -- 3.7.x etc etc
