Configure BACnet Driver for NK823x

You can create one or more BACnet drivers. However, note that the fire system should always use a dedicated BACnet driver.

  • When you work on a FEP station, the Drivers folder must be available in System Browser. You can create it using New .
  • You have an understanding of how your fire BACnet network is structured. For more information, refer to BACnet Network.
  1. In System Browser, depending on whether the driver runs on the server or FEP station, select one of the following:
    - Project > Management System > Servers > Main Server > Drivers
    - Project> Management System > FEPs > [FEP] > [drivers folder]
  1. In the Object Configurator, click New , and select New BACnet Driver.
  1. In the New Object dialog box, enter a description.
    NOTE: The description must be different from that of any other driver on the server or FEP stations.
  1. Click OK.
  • The newly created driver is automatically selected in System Browser.
  1. Select the BACnet tab and open the Settings expander.
  1. In the Management Station section, enter the Instance number: the BACnet Device Identifier to assign to the driver as a BACnet client (default: 9998).
    NOTE: The Instance number must match the BACnet device ID set in the BACnet client configuration of the panel configuration tool.
  1. In the Registered Process IDs section, do the following:
    a. Select the default value 0 and click Remove.
    b. Select the default value 600 and click Remove.
    c. In the entry field, enter 1 and click Add.
  • The selection list only displays the value 1.
  1. In the Extended Operation tab, select the Manager Status property and click Start, to fully activate the driver, or click Start Conf… (start in configuration mode), to run the driver without activating any real connection to the field.
  1. Open the BT BACnet Stack Config expander.
  1. In the BT BACnet Stack Gateway Port Table, click Add and select BACnet/IPV4.
  1. In the Port Properties expander, set the Network Number where your management station is connected (typically =1).
  1. In Port id, set the same value as in Network number.
  1. Select the hardware adapter in the Adapter drop-down list.
    NOTE 1: You must start the BACnet driver in full mode to select the network adapter. If you are configuring offline, you need to postpone this step.
    NOTE 2: The IP address and UDP port (default: 47808) of each physical port have to be unique. If two drivers are assigned to the same Network Interface Card (NIC), you can use the value 47809 for the UDP port of the physical port of the second driver.
  1. (Optional) To configure the station as BBMD, do the following:
    a. In the Port Properties expander, select the BBMD tab and then select BACnet Broadcasting Management Device.
    b. Configure Broadcast distribution table, Foreign device table and NAT Global Address as required by the BACnet network.
  1. (Optional) To configure the station as Foreign Device, do the following:
    a. In the Port Properties expander, select the Foreign Device tab and enable Foreign Device.
    b. Configure IP Address and UPD Port of the Remote BBMD.
    c. (Optional) Adjust the Time to live parameter (default is 1800 sec).
  1. Click Save .

In the BACnet tab, the Threads and Driver Devices expanders are not used.

Multiple BACnet connections can share the same BACnet driver as long as the Device Identifier required for the driver is the same for the connected BACnet networks. If the identifier is different across the networks (that is, if the BACnet client configuration on all networks does not include a common Device Identifier), then you must create separate drivers.
