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).
