Read/Write
Read/write.
Note: OpenLNS sets this property automatically for message
monitor points. For example, if you are sending a message
via the SendMsgWait method, a response from the device is
expected. Therefore, OpenLNS will set the UseAsyncSend
property to False.
Also, if you are writing to a message monitor point via the
SendMsgWait property, no response is expected; therefore,
OpenLNS sets the property to True. As a result, you should
not write to this property when you access it through a
MsgMonitorOptions object
Added to API
LNS Release 3.20.
UseBoundUpdates
Summary
Indicates whether NvMonitorPoint objects should use bound
updates for monitor and control.
Enabling bound monitoring and control will not disable
polling unless the SuppressPollingIfBound is set to true.
This property enables implicit binding. With implicit binding
enabled, OpenLNS attempts to create connections without
user intervention.
Attempting to set this property in the CurrentOptions object
will fail silently for both permanent and temporary monitor
points. To use bound updates for a permanent monitor point,
you must set this property in the DefaultOptions object. If
you are in communication with the OpenLNS Server (not in
server-independent mode), this option will be automatically
enabled as soon as you set the property to True. In this case,
you don't have to close and re-open the monitor set, as with
other options in the DefaultOptions object. You cannot set the
properties of the DefaultOptions object in server-independent
mode.
OpenLNS does not support the automatic connection of
monitor points in temporary monitor sets; therefore, this
property should be set to False for NvMonitorOptions objects
that are accessed through the NvOptions property of
MonitorSet objects created as temporary monitor sets.
Availability
Local, full, lightweight, and independent clients. Note that
objects and temporary monitor points
are not available on Independent clients.
