Use the ObixPointManager to add, edit, and access Obix proxy points under the Points extension of a selected ObixClient, R2ObixClient, or in an ObixPointFolder. The ObixPointManager is the default view on all these components. To view, double-click the Points extension or ObixPointFolder, or right-click and select ->.
As in some other point managers, there is a Discovered table (if in Learn mode) and a Database table. Every object on the remote server can me modeled as a point in the station. Non-value objects are modeled as string points, and their value is the oBIX display string.
During discovery, results are cached. Therefore if the server database is modified after a discovery has occurred (or while a discovery is in progress), the discovery pane may be inaccurate. Click the button again to clear the cache.
For details specific to an Niagara R2 to AX application, see the “R2ObixClient Points” section in the engineering notes document Niagara R2 to NiagaraAX via oBIX.
The Discovered table in the ObixPointManager view has the following available columns:
-
Obix Name
Name of the object on the oBIX server.
-
Value
Value of the object at the time of discovery (expansion of its parent’s leaf in the lobby).
-
Mode
Either RO (read-only) or RW (read-writable). Note that an Obix proxy point for a RW item can be created either as a read-only type (NumericPoint, BooleanPoint, etc.) or as a writable type (NumericWritable, BooleanWritable, etc.).
-
Href
The URI of the object on the oBIX server.
By default, the following columns appear in the Discovered table of the ObixPointManager view:
-
Name
Niagara name of the proxy point, if a “root level” point often left the same as the (discovered) object item name.
-
Type
Niagara type of component, as either an Obix Point Folder (for a folder) or a type of control point if an Obix proxy point (for example, Boolean Point, Boolean Writable, Numeric Point, and so on).
-
To String
Last read value of a data item.
-
Href
The URI of the object on the oBIX server.
-
Fault Cause
String describing the cause of the proxy point status fault, if any.
In addition, using the table options control, the following additional data columns are available:
-
Enabled
Reflects whether proxy point is enabled (true) or disabled (false).
-
Facets
Reflect the facets in use by the proxy point.
-
Conversion
Niagara conversion type used by the ObixProxyExt, which is typically Default.
-
Tuning Policy Name
Name of the Niagara ObixTuningPolicy that the proxy point is assigned to.
-
Device Facets
Reflects the read-only device facets used in the point’s proxy extension.
-
Path
Station path of the proxy point component, relative to the root.
-
Read Value
Reflects current read value in point’s ObixProxyExt.
-
Write Value
Reflects current write value (if any) in point’s ObixProxyExt.
-
Subscription
Reflects whether proxy point is Subscribed, Unsubscribed, or Pending subscription.
