Config, BV (Bacnet Binary Value)

This component is a Config object that represents a BACnet Binary Value object in its entirety.

To access these properties, copy an BV component from the bacnet palette (Config folder) to the BacnetDevice > Config folder and double-click the component.

In addition to the common properties (Status and Fault Cause), this component has these properties.

Property Value Description
Poll Frequency drop-down list (defaults to Normal)
References the On Demand Poll Scheduler rates under the NiagaraNetwork’s History Policies container slot.

Configures how often this type of poll occurs.

Object Id drop-down list and number (from 0 to 4194302)
Identifies each device and component by the type of entity (Object Id) combined with a unique Instance Number.

For devices (controllers, instruments, meters, etc.), Instance Number must be unique within the BACnet internetwork. For components (points, schedules, analog inputs, files, groups, multi state inputs, etc.), it must be unique within the device.

Object Name text in the format name.name.name.name (default includes the entire component path in the station using period (“/) delimiters between parent.child levels)
Identifies a BACnet object. This name should be unique within this specific device.

For components, this name includes the entire component path under the station’s Config using period (.) delimiters between parent.child levels. This enforces (externally) the BACnet requirement for unique names for all objects in a device.

For a proxy point, this is the default name in the station.

You can shorten or edit Object Name, however, each Object Name must be unique among all server descriptors under the Export Table.

Object Type drop-down list of BACnet objects
Reports the type of object.
Present Value (config group) list
Represents a BACnet list containing a non-indexed sequence of objects of a particular BACnet data type.
Facets Config window or read-only property
Determine how values are formatted for display depending on the context and the type of data. Examples include engineering units and decimal precision for numeric types, and descriptive value (state) text for boolean and enum types.

With the exception of proxy points (with possible defined device facets), point facets do not affect how the framework processes the point’s value.

Besides control points, various other components have facets too. For example, many kitControl and schedule components have facets. Details about point facets apply to these components too, unless especially noted.

You access facets by clicking an Edit button or a chevron >>. Both open an Edit Facets window.

Status Flags read-only indicator and check boxes
Configures four status flags for BACnet. These options are available to enable detection of specific status conditions.
Event State read-only
Reports the status of the event.
Out of Service true (default) or false
Affects only the BACnet exposure and access to the source component. If the source (exported) component is a proxy point, the equivalent Enabled property in its ProxyExt is not affected.

true writes the point’s current value to the Present Value property. Often, a remote BACnet client sets (or clears) this Out of Service state.

You can set this property to false if needed.
