This window opens when you expand Config > Drivers, double-click BacnetNetwork and click New or select a row and click Edit in the Bacnet Device Manager.

Property Value Description
Name text Provides a name for the device.
Type drop-down list
Identifies the type of BACnet object, for example, Analog Input, Analog Output, Calendar, Schedule, Structured View, File, Trend Log, BooleanWritable or other.

Writable components typically offer more type selections than read-only points, such as:

  • Two read-only: input or value type, e.g. Binary Input or Binary Value object.
  • Two writable: output or prioritized value type, e.g. Binary Output or Binary Value Prioritized object.

    The screen capture shows an example of type selections when exporting an NdioBooleanWritable point.

Device ID additional properties Identifies the object as a device and adds a unique instance number.

These properties do not affect the device’s ID in the station database.

Netwk additional properties
Contains network-related properties. Refer to separate topics in this document.
MAC Addr text
Displays the Media Access Control (MAC) address.
Enabled true (default) or false
Activates (true) and deactivates (false) use of the object (network, device, point, component, table, schedule, descriptor, etc.).
Use Cov true or false If the device was discovered, and station database determined that the device indicates support for server-side COV, this property defaults to true. Otherwise, it defaults to false indicating that no proxy points under the device use COV.
Enables (true) and disables (false) a device’s support for COV (change of value) as a way to monitor proxy point values.

Assuming the device supports subscription to the COV service, true triggers the driver to attempt the necessary updates (proxy subscriptions) to the value of each point using the BACnet COV subscription to the device. If the subscription attempt succeeds, the Read Status property of the point’s BacnetProxyExt displays COV. If the subscription attempt fails, the driver uses normal polling and the Read Status property shows Polled.

When true, individual proxy points under the device may use COV subscriptions, depending on their assigned tuning policy.

When false, the driver ignores any proxy subscription updates.

Max Cov Subscriptions text (defaults to max) Specifies the maximum number of COV (change of value) subscriptions that the database attempts to use with this device. This restriction prevents the station from consuming all of the available subscription space in the device. Applies only if Use Cov is true.
