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.
GenerateInitialFetch
Summary Determines if the network variable value is fetched
automatically when the network variable monitor point is
enabled .
Availability Local, full, lightweight, and independent clients. Note that
temporary MonitorSet objects and temporary monitor points
are not available on Independent clients.
Syntax initialFetchValue = nvMonOptObject.GenerateInitialFetch
Element Description
initialFetchValue An Integer value indicating whether
the network variable value is fetched
automatically when the network
variable monitor point is enabled.
1
The NvMonitorPoint object
automatically gets the value of
the network variable it monitors
when it is enabled using the
Enable method, implicitly enabled
when it is opened, and the
doEnable element is set to True.
0 The value will not be updated
until an update is received, either
due to normal polling activity or
via bound updates. This is the
default.
-1 The value is set to the value
currently stored in the NvOptions
property of the MonitorSet object.
This may be useful if you want
the value of the property used by
a network variable monitor point
to always match the default value
stored in the MonitorSet object.
This feature, however, is not
available in server-independent
mode.
nvMonOptObject The NvMonitorOptions object to be
acted on.
