Good afternoon,

I am looking for information on the maximum number of objects that can be registered on an LM 5 Lite as an IP bacnet client?

I'm browsing through the manual and I can't find the data, maybe all the memory of the device is shared?

I am planning an application that requires several integrations with IP bacnet servers (1500 bacnet objects aprox.), and also a good part of KNX (about 120 knx devices approximately). I'm not sure whether to put 1 or 2 LM...

Thank you very much for your expert comments!

Greetings !!!

The current BACnet client implementation is rather limited as everything has to be done via scripts and only a single script can handle all communication. If only reading BACnet devices is required then it can be done. If both reading and writing is needed I would not recommend more than 50-100 objects in total. There's also an app but it uses the same approach so the same limitations apply.
If LM is a BACnet server then it can handle 1500 objects.
