3. BACnet interface

3.1 Description

The BACnet systems are represented in the form of Devices holding Objects, normally every
physical device corresponds to a logical one. The Objects can be of different type depending
on their task: analog input, analog output, digital input, etc, up to 23 different types of
objects. Every Object has different properties, the one more commonly used, and the one
used to read and write values in the gateway is the Present Value property that indicates
the real value of the object. Every Object of the same type in a Device is identified with its
associated Object Instance.
These are the possible BACnet signals supported by the gateway:
Object Type Property
Analog Input Present Value
Analog Output Present Value
Analog Value Present Value
Binary Input Present Value
Binary Output Present Value
Binary Value Present Value
Multistate Input Present Value
Multistate Output Present Value
Multistate Value Present Value
Multistate signals represent integer values, the same than binary ones but with more than 2
possible statuses. Input signals are read only signals.
Every signal is identified with its associated Device + Object Type + Object Instance.
The gateway simulates a virtual BACnet device inside the BACnet system acting as one
more device of the BACnet system. The communication with the rest of the BACnet devices
is done via the Ethernet port of the gateway which implements the BACnet IP protocol.
