You can selectively choose writable control points in the station (BooleanWritable, EnumWritable, NumericWritable, and StringWritable) to expose to external oBIX clients for write access at a particular control level. Note this includes any writable proxy points in the station.
To expose writable control points for external link control
Use the following procedure to expose writable control points for prioritized input writes.
-
Right-click the station’s ObixNetwork and select ->.
The Property Sheet appears.
-
Double-click the Exports folder
.
The Obix Export Manager view appears
-
Click the button in the export manger.
This opens the station’s Config component tree in the discovered pane, as an expandable node.
-
In the discovered pane of the Obix Export Manager, expand the component tree. Note that only writable control points are shown (other component types are filtered from view).
-
Double-click a point to add an export descriptor.
The Add dialog appears, in which you select its “Name” and the priority level (Priority) of its input you wish to expose to oBIX. For details, see Reserving writable inputs for oBIX client access.
-
Click .
This adds the export descriptor to the database, where it is visible in the database pane of the view, showing the current value of the writable point. Note this automatically creates a link (nub) on the target writable control point, such that link contention from within Niagara will not occur.
-
Continue to add Obix Exports as needed under the Exports folder of the ObixNetwork.
