4.2.1.3 Scope of Use in Building Automation 
The use of BACnet devices has the advantage that many different devices and 
networks can be simply connected with each other and administrated. In doing 
so, the BACnet Protocol covers communication on the automation and man-
agement levels.

4.2.1.4 Management Level 
On this level, the processes of building automation are continuously analyzed, 
improved, stored and evaluated. Functions of this level are also necessary for 
transmitting input and output values to the management levels of foreign sys-
tems. For communication between heterogeneous systems, these must be 
linked in a manner that is interoperable, i.e. correspond in the communication 
structure (see sections 
4.2.1.2.4 and 4.2.1.2.5).
