7.4.- BACnet PROTOCOL
BACnet is a communications protocol for Building Automation and Control NETworks. This protocol
replaces the proprietary communications of each device, making it a set of common communication
rules that enables the complete integration of the building automation and control devices of different
manufacturers.
The device features BACNet MS/TP communications, following the specifications of ANSI/ASHRAE
135 (ISO 16484-5).
Using a RS485 connection, the device can connect to a BACnet and include all of the objects and
services defined in the attached PICS map (Protocol Implementation Conformance Statement). (“7.4.1.
PICS MAP”)
The default speed is 19200 bps and the MAC is 2 (node number), and can be changed on the
configuration screen or by entering the BaudRate and MAC_Address variables. The identifier (Device_
ID) can be changed on the configuration screen using the writing property over the variable or through
the Device_ID variable.
Another option is to overwrite the Object_Name in the Device object:
a) #Baud x – where x can be: 9600, 19200, 38400
b) #MAC x – where x can be: 0 ... 127
c) #ID x – where x can be: 0 ... 99999
