Binding proxy points

By default, when you add nvs (nvi or nvo) proxy points, the station polls each point to update its value. For may proxy points, particularly network variable outputs (nvos), polling is less efficient than binding them from the source device (sending) to the target local Lon device (receiving). Then, the station updates them using the native Lonworks nv update mechanisms, reducing the polling queue. Binding output to input proxy points improves communication efficiency.

The station does not poll ncis and cps (SCPTs) proxy points. It updates these values when you upload from the Lon device or issue a Force Read action for the corresponding Lon components.

You bind nvs used for Lon proxy points unless there is a specific reason not to do so. One possible scenario may include devices with nvos that send updates too frequently, and there is no way (in such devices) to adjust the minimum write time upwards. In this example, even after a global bind, you can specifically pick nvs (in srcDevices) to change to Poll Only.

Perform the following steps:

In the Nav side bar, right-click the Lon network node and click Views > Lon Link Manager.
The Lon Link Manager opens. Each newly-added proxy point appears as a row in the NetworkVariableLinks tab, with a linkStatus of NewLink. By default, each point uses a linkType of Standard.
If needed, click on the host column header to sort the table by devices.
This groups nvo sources together by Lon device name.
Do one of the following:
- To bind all proxy points, click the Bind button.
- To bind a subset of proxy points, select the points and click the Selective Bind button.
A progress bar displays at the top of the manager. When the bind job finishes, the linkStatus of entries for proxy points or selected points should show as Bound.
To verify the bind, right-click the Lon network node in the Nav tree, click Views > Lon Utilities Manager, configure Command: Reports and SubCommand: Verify, and click Execute.
Check the report to ensure that each device’s nv bind configuration matches the network management configuration stored in the station.
