M172 and BACnet Geteway interaction

[a_shapoval_mers]

Dear support, I am new to TM172 BACnet conception. 

Are there opportunities for interaction between the TM172 PLC and the Bacnet 3d Device?
I see a lot of documentation about how to implement TM172 as a BACnet data source, but I need to 
implement some service within TM172 that will be able to read/write some BACnet objects from the 3d BACnet gateway. 
Is it possible? What libs or predefined functions (function blocks) should I use or download?

Actually the TM172 could only receive data via BACnet. In one of the next version will be also a write possibility integrated.
