ClassId
Summary Identifies the object class of this object.
This property allows the object type to be determined when it
is unknown (for example, when the object was accessed using
the Parent property of another object).
Availability Local, full, lightweight, and independent clients. Note that
some objects containing this property are not available to
Independent clients.
Syntax classIdValue = object.ClassId
Element Description
classIdValue The object class of the object. The
following value is defined for the
NvMonitorPoint object in the
ConstClassIds constant:
80 lcaClassIdNvMonitorPoint
object The object to be acted on.
Data Type Integer.
Read/Write Read only.
Added to API Depends on the object used to access the property. Generally,
this property exists for an object as soon as the object is
added to the API.
CurrentOptions
Summary Contains the current monitoring options for this network
variable monitor point. Once the monitor set containing a
monitor point has been opened, you can use this property to
set the monitoring options that will be used for the monitor
point during that particular session .
For monitor points in MonitorSet objects created as
permanent monitor sets, the options contained in this
property default to the options set in the DefaultOptions
property of the NvMonitorPoint . If the options are not set
there, they default to the options set in the NvOptions
properties in the MonitorSet object.
Each time a permanent MonitorSet object’s Open method is
called, the current options for each of the monitor points in
the set are reset to the options contained in their
CurrentOptions properties. The CurrentOptions property can
only be written to when the monitor set is open.
The
NvMonitorOptions object contained within this property
is not passed by reference. If you acquire an
NvMonitorOptions object through the CurrentOptions
property and modify it, you must then explicitly assign the
modified object back to the CurrentOptions property for the
changes to take effect. This following code sample
