OpenLNS Programmer's Reference 633
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
temporary MonitorSet objects and temporary monitor points
are not available on Independent clients.

The NvMonitorOptions object to be
acted on.
Data Type

Read/write.
Added to API
LNS Release 3.0.
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 NvOptions property of a
permananent monitor set, or through the DefaultOptions
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
the UsePriorityFlag property of the ConnectDescTemplate
specified when the network variable monitor point was
created.
You cannot set this property through the DefaultOptions
property of a temporary network variable monitor point, as
the DefaultOptions properties of all temporary monitor points
are not accessible. However, you can set this property
through the NvOptions 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.
