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.), |
| 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 Type | drop-down list of BACnet objects |
Reports the type of object.
|
| Present Value (config value) | 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.
You can set this property to |
| Output Units | drop-down list | Selects unit of measure for output. |
| Manipulated Variable Reference | additional properties | Configures variables. |
| Controlled Variable Reference | additional properties | Configures variables. |
| Setpoint Reference | additional properties | Configures setpoint references. Refer to Reference in this dictionary.
|
| Setpoint | number to two decimal places | Configures the point’s setpoint value. |
| Action | drop-down list (defaults to Direct)
|
Selects the type of action: Direct or Reverse.
|
| Priority for Writing | numeric text values 1 through 16 |
Reports schedule priority, which defaults to 16.
