BACnet Settings

Configuring BACnet involves setting up BACnet server parameters in the controller. The Building Management System (BMS) discovers the exposed data through this configuration.

Here are the steps for configuring the controller as a BACnet server:

1. Navigate to Configurator → Utilities → System → Network → BACnet settings dialog.
   

2. Configure the following parameters:

   • Server enabled: Enable or disable the BACnet server.

   • Device ID: Ensure that the BACnet device ID is unique on the BACnet network.

   • Device name (optional): By default, the BACnet name is composed of the controller´s hostname followed by the Device ID. If you fill in the Device name, the BACnet name will match it.

   • Password: Set the BACnet password.

   • Object priority: Define the priority array to which the controller will write. The controller writes to the Relinquish Default (RD) property by first reading (upload from BMS) only. It takes the current value of the object. The value of the RD property cannot be changed afterward. If an object read from the controller has a higher value than the RD property, it raises the Overwritten flag.

   • Add the KNX address to the object name: KNX address will be included in object’s name.

   • Use comments as object description: E.g., ETS import will be used as an object description.

   • Convert object units to BACnet units: When enabled, it ensures that the units used by the object (e.g., temperature in Celsius or Fahrenheit) are correctly translated to the standard BACnet units (e.g., degrees Celsius).

   • Port: Specify the BACnet port (default is 47808).

   • BBMD Configuration: Set the BACnet router IP (BBMD IP) and port (BBMD port). Configure the BBMD lease time (seconds) for registration resend intervals.

3. Click OK to save your settings.
