The Lon Poll Service sequentially poles all the devices on the network, and reads nv data per the nv update rules.

The driver polls proxy points when you first create the points and before you bind Network Values (nvs) to the station (local device) using the Lon Link Manager. You bind nvs so that most updates occur using nv updates, vs. polling requests. As necessary, polling also occurs to update nv values of Lon components (visible as nvis and nvos in the property sheet of a Lon device). These exist even if proxy points are not created.
