By default, when you add Lon proxy points for nvs (nvi or nvo), each one is polled to obtain value updates. See Network variable (nv) poll/update rules.

Proxy points for ncis or cps (SCPTs) are never polled. These point values are obtained when you Upload from the Lon device (see Lon device actions), or issue Force Read actions to the corresponding LonComponents (see LonComponent actions).

Typically, instead of polling device’s nvs for Lon proxy points (especially nvos), you bind those nvs to the LocalLonDevice. Then, updates occur using the “native Lonworks nv update” mechanisms, reducing the polling queue. You do these binds using the Lon Link Manager view of the LonNetwork. See Bind Lon proxy points for procedures.
