Configure the BACnet Driver for STT20

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

  1. Depending on where the driver runs (on the server or FEP station), in System Browser select one of the following:
    - Project > Management System > Servers > Main Server > Drivers
    - Project > Management System > FEPs > [FEP] > [drivers folder]
    NOTE:     When you work on a FEP station, the drivers folder must be available in System Browser. You can create it using New .
  1. In the Object Configurator, click New , and select New BACnet Driver.
  1. In the New Object dialog box, enter a unique description.
    NOTE: All drivers must have a distinct description, even if they are running on different 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).
  1. In the Extended Operation tab, select Manager Status 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. Select the hardware adapter in the Adapter drop-down list.
    NOTE: You must start the BACnet driver in full mode to select the network adapter. If you are configuring offline, you must postpone this step.
  1. Click Save .

 

NOTICE

If you create more than one BACnet driver, the drivers can be assigned to the same Network Interface Card (NIC) or to 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 is 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 example, 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.

 

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.
