By default, when you add Lon proxy points, the source LonComponent nvs are all polled for values. For many proxy points, particularly nvos, this is less efficient than binding (from the source device) to the target LocalLonDevice, such that Lonworks nv updates are received.
Once you have added Lon proxy points under one or more devices, you typically bind to receive nv updates. The following procedures explain how:
To bind all Lon proxy points
Typically, you bind to all nvs used for Lon proxy points, unless there is a specific reason not to do this. One possible scenario may include devices that have nvos that send updates too frequently, and there is no way (in such devices) to adjust the “minimum write time” upwards.
In that example scenario, even after a global command in the Lon Link Manager, you can specifically pick nvs (in srcDevices) to change to “Poll Only.”
To bind Lon all proxy points, use the following procedure:
-
In the Nav side bar, right-click the LonNetwork and select ->.
This brings up the Lon Link Manager.
Each newly-added proxy point appears listed as a row in the NetworkVariableLinks tab, with a linkStatus of “NewLink.” By default, each point uses a linkType of “Standard.”
-
Click the Bind button to invoke a Lon Bind job.
A progress bar displays at the top of the manager, and the bind job finishes. Now, the linkStatus of entries for proxy points should show as “Bound.”
See Lon Link Manager for more details.
To bind some Lon proxy points
You can selectively bind to only some nvs used for proxy points, and leave others at the current link status (including “NewLink”).
To bind only some Lon proxy points, use the following procedure:
-
In the Nav side bar, right-click the LonNetwork and select ->.
This brings up the Lon Link Manager.
Each newly-added proxy point appears listed 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 srcDevice column header to resort the NetworkVariableLinks table by devices (this groups nvo sources together by Lon device name).
-
In the NetworkVariableLinks table, click to select the nvs for proxy points you wish to bind.
-
Click the Selective Bind button to invoke a Lon Bind job.
A progress bar displays at the top of the manager, and the bind job finishes. Now, the linkStatus of entries for the selected items should show as “Bound.”
