Property Name

Description

ResetPollingIfUpdated

Use this property to determine whether or not the poll

interval for each network variable monitor point in the

set will be reset whenever a new value for the point is
received, either via a bound update or a read operation.

If

True

, the poll interval will be reset.

For example, consider a case where the poll interval is

set to 100 seconds. If this property is set to

True

and a

new value for a monitor point is received, LNS would

reset the polling cycle and wait another 100 seconds to

poll that network variable again.

If this property is set to False, and LNS receives a new

value 35 seconds after the most recent poll, LNS would
not reset the polling cycle. The next poll would occur 65

seconds later.

Default Value: True

Retries

This property determines the number of retries to use for

acknowledged, request/response messages, and for
repeat service messages during the current monitoring

session.

Setting this property through the NvOptions property of

a permanent monitor set, or through the
DefaultOptions property of a permanent network

variable monitor point, does not have an effect. The

default retry count for each permanent network variable
monitor point is established by the RetryCount

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 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 retry count that will be applied to all network

variable monitor points as they are added to the set.

Remember that you can set this property through the
CurrentOptions property of a permanent or temporary

network variable monitor point to determine what retry
count to use when sending network variable updates

during the current monitoring session.

Default Value: For permanent monitor sets, the default

value for this property is 3. The default value for
temporary monitor sets is set to match the value of the
DsRetries property.
