Discovering objects
With the exception of drivers that do not support online discovery and the quick–learn option for discovering devices in a
LonNetwork, object discovery (learn) is a two-step process: discover, then add or match. Objects to discover include stations, devices,
points, schedules and histories. Discovery is available using the manager views. The managers provide a two-pane view with
Discovered and Database tables as well as a single-pane view with only a Database table. This is a general procedure that works for all drivers.
Prerequisites: You are working in
- Navigate to a manager view, such as Device Manager (NiagaraNetwork node), Points Manager (Points node), or other node and double-click the node in the Nav tree.The manager view opens.
- Click the Discover button at the bottom of the view or the Discover tool in the toolbar (
).The Discover tool is available only if the driver supports online discovery.Some drivers open an intermediate window before the discovery job begins to run. For example the BACnet driver opens a Configure Device Discovery window, which limits the discovery job to a specific range.
- Configure any discovery options and click OK.The discovery job splits the screen into two panes and, as it runs, displays a progress bar along the top of the Discovered pane.
After the job completes:
- The Discovered pane lists the discovered objects that can be added to the database.
- The Database pane displays any objects already in the database.
You can drag the horizontal border between the panes up and down.
- Do one of the following:
- If a discovered object is not yet in the database, select it in the Discovered pane and click Add or click the Add tool (
) or right-click the discovered row and click .
- If a record for the discovered object was added to the database while the station was offline, select the object in the Discovered pane and its database record in the Database pane and click Match or click the Match tool in the toolbar (
).
NOTE: Match is strictly a one-to-one function for discovered-to-database records. It is unavailable if multiple items are selected in either the top or bottom pane.
When you click Add or Match, a window opens. The properties in this window depend on the driver.This window is nearly identical to the single-device Edit window and usually includes the object address. When matching, most properties already have acceptable values, otherwise communication to the discovered object would not have occurred.
- If a discovered object is not yet in the database, select it in the Discovered pane and click Add or click the Add tool (
- To edit an object database record, select it in the Database pane and click Edit.
- To toggle between learn mode (the view that displays both the Discovered and Database tables) and single-pane mode (Database table only), click the Learn Mode tool (
).
