NvOptions property of the MonitorSet object. This may
be useful if you want the poll interval for the monitor
point to always match the default value stored in the
MonitorSet object. However, this feature is not available
in server-independent mode.
When writing to this property, the amount of polling you can
do on a network depends on the speed of the communication
channels being used by the network, and the amount of
traffic on those channels. The poll interval you select
combined with the number of network variables being polled
by the OpenLNS Server may significantly increase the
amount of traffic on your network. When you write to this
property, ensure that the poll interval you specify does not
cause your network resources to be exceeded.
Availability
Local, full, lightweight, and independent clients. Note that
objects and temporary monitor points
are not available on Independent clients.

Priority
Summary
Determines whether priority is used when polling or
explicitly updating a network variable monitor point using
the Value property.
Setting this property through the
permananent monitor set, or through the
property of a permanent network variable monitor point,
does not have an effect. The default priority setting for each
permanent network variable monitor point is established by
property of the
specified when the network variable monitor point was
created.
You cannot set this property through the
property of a temporary network variable monitor point, as
properties of all temporary monitor points
are not accessible. However, you can set this property
property of a temporary monitor set
to determine the default priority setting that will be applied
to all network variable monitor points as they are added to
the set.
