6.4.- 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 unit incorporates BACNet MS/TP communication, following the specifications of ANSI/
ASHRAE 135 (ISO 16484-5).
Using a RS485 connection, the analyzer can connect to a BACnet and include all of the
objects and services defined in the attached PICS map (Protocol Implementation Conformance
Statement). ( “ 6.5.- PICS MAP” )
The default speed is 38400 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, 57600, 76800, 115200
b) #MAC x – where x can be: 0 ... 127
c) #ID x – where x can be: 0 ... 4194303
