Property Name Description
SuppressPollingIfBound This property determines if polling will be turned off for
monitor points whose target network variable is bound to
the host device. If
True
, polling will be turned off. In this
case, polling will be turned off even if the monitor point
does not use bound updates, as long as the target
network variable is bound to the host device through
some other means.
For example, if an network variable is explicitly
connected to a dynamic network variable on the Network
Service Device (perhaps via a fan-in connection), bound
updates from that network variable will be reported on
all the network variable monitor points monitoring the
output network variable, and if the
SuppressPollingIfBound
property is True, the output
network variable will not be polled.
Default Value: True
ThrottleInterval This property contains the default throttle interval for
network variable updates for the set. This sets the
maximum interval between successive
OnNvMonitorPointUpdateEvent
or
OnMsgMonitorPointUpdateEvent
events that can be
generated by the monitor set.
If multiple updates are received within the throttle
interval, LNS will not fire a second event until the
throttle interval has expired, and will then fire an event
for the last update received. Thus, if this property is non-
zero and multiple updates are received within this
interval, events will only be fired for the first and last
updates. And so some updates may be lost. This value
should never be greater than the polling interval, since
that would guarantee that some polled updates would be
lost, and would waste network bandwidth.
Default Value: For permanent monitor sets, the default
value for this property is 1000ms. The default value for
temporary monitor sets is set to match the value of the
DsPollInterval property.
UseAsyncSend Use this property to determine whether or not LNS will
wait for a completion code to return after updating the
value of a monitor point, before returning to the user and
sending its next update message. If
True
, LNS will not
wait for a completion code.
Default Value: False
