To discover I/O points

Perform this task to discover I/O points.

To discover I/O points of an NdioBoard:

1. In the Ndio Device Manager, in the Exts column, double-click the Points icon   in the row representing the NdioBoard you wish to explore.

   This brings up its Ndio Point Manager.

2. Click the Discover button to learn what I/O points are on the NdioBoard.

   When the discovery job completes, discovered I/O points are listed in the top pane of the view, in the “Discovered” table. Each I/O point occupies one row.

3. To add Ndio proxy points, see add.

To add discovered I/O points as Ndio proxy points

Perform this task to add Ndio proxy points.

To add discovered I/O points as Ndio proxy points:

1. Select the I/O point or points in the Database pane of the Ndio Point Manager.

2. You can map selected points in the station in different ways:

   • Drag from the Discovered pane to Database pane (brings up an Add dialog).

   • Double-click an item in the Discovered pane (also brings up an Add dialog).

   This works the same as in other driver’s Point Manager views.

3. When the Add dialog appears, you typically edit a number of fields for each I/O point. For complete details, see Ndio Point Manager usage notes.

   The following brief summaries explain Add dialog fields:

   • Name is the Ndio proxy point name—you typically change this to describe the I/O purpose.

   • Type is the Ndio “type,” which is selectable for any “universal input,” but fixed for any output. See Universal Input selection notes and Output type selection notes.

     Unlike other entries in the Add dialog, you cannot edit the point’s Type later.

   • Address is the learned I/O point’s hardware address.

   • Poll Frequency specifies the point’s poll frequency group (default is Normal).

   • Conversion specifies the conversion type used between the Ndio proxy extension’s “Device Facets” and the parent point’s facets. See Conversion types in Ndio proxy points.

   • Facets are the Ndio proxy point’s facets, for how the value should be displayed in Niagara.

4. When you have Ndio proxy point(s) configured properly for your usage, click OK.

   The proxy points ares added to the station, and appear listed in the Database pane.

   For more details, see About Ndio proxy points.

   In cases where you notice a fault status for input points you have edited with “non-default” facets, this is likely related to a mismatch of the “Units” in the point’s automatically-appended Linear Calibration Ext. To clear this fault status, expand the point’s Linear Calibration Ext and edit Units to match the units in the point’s facets.For more information, see Linear Calibration Ext.
