(Optional) Create a BACnet Driver for 3rd Party Integration

The workflow is only necessary if there is no available BACnet driver for the BACnet network for third-party devices.

Creating BACnet Driver

  • The required driver is not on the server's driver list.
  1. Select Project > Management System > Server > Server > Driver.
  1. Click New , and select BACnet driver.
  1. In the New object dialog box, enter a description.
  1. Click OK.
  • The new driver is available in System Browser.
  1. Select the new driver.
  1. Select the BACnet tab and open the Settings expander.
  1. In the Management Station section, enter the instance number of the BACnet BACnet Networks for Desigo PX, assigned to the driver as a BACnet client for the BACnet system (for example 34590). The number must be unique on the UDP network.

Starting a BACnet Driver

  1. Select the new driver.
  1. In the Extended Operation tab, next to the Manager status, click Start.
  • The command status displays.

Configure BT BACnet stack

  1. Click the BACnet tab.
  1. Open the BT-BACnet Stack Config expander.
  1. In the BT BACnet stack gateway port table, click Add and select one of the following options:
  • Select BACnet/IP or Ethernet to add a physical port. In the Port Properties expander, set the Network number where your management station is connected (typically =1, unless in conflict with the Network number of the virtual port) and select the hardware adapter in the Adapter drop-down list. (For IP address and UDP Port BACnet/IP settings, see the following guidelines.)
    Note: You need to start the BACnet driver in full mode to select the network adapter. Postpone this step if you are configuring offline.
  • Select Virtual, to add a virtual port.
    Note: Any subsequent change in the Network number field of the Settings expander is automatically reflected in the Network number field of the virtual port.
  1. (optional) Configure the physical port as BBMD or Foreign Device.
  1. Click Save .
  • The new driver is available in System Browser.

If setting up multiple BACnet drivers, you can assign them to the same network card (Network Interface Card, NIC) or different NICs. To avoid configuration conflicts, apply the following guidelines to the physical port configuration:

  • The network number of each physical port must be unique.
  • The IP address and UDP port (default: 47808) of each physical port must be unique. This means that the Physical Ports must have a different IP address or a different UDP port. For instance, if two Drivers are assigned to the same NIC, you can use the value 47809 for the UDP port of the Physical Port of the second Driver.
