Property Name Description
Retries This determines the number of retries to use for
acknowledged, request/response, or repeat service messages.
Setting this property through the MsgOptions property of a
permanent monitor set, or through the DefaultOptions
property of a permanent message monitor point, does not
have an effect. The default retry count for each permanent
message monitor point is established by the RetryCount
property of the ConnectDescTemplate specified when the
message monitor point was created.
You cannot set this property through the DefaultOptions
property of a temporary message monitor point, as the
DefaultOptions properties of all temporary monitor points
are not accessible. However, you can set this property
through the MsgOptions property of a temporary monitor
set to determine the default retry count that will be applied
to all message 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
message monitor point to determine what retry count to use
when sending messages using this message monitor point
during the current monitoring session.
Default Value: For permanent monitor sets, the default
value for this property is 0. For temporary monitor sets, the
default value is set to match the
DsRetries
property of the
System
object.
ServiceType This property specifies the default messaging service to use
when sending explicit messages with this monitor set or
monitor point.
Default Value: For permanent monitor sets, the default
value for this property is the acknowledged message service.
For temporary monitor sets, the default value is set to match
the
DsService
property of the
System
object.
UseAsyncSend LNS 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, LNS would set the
UseAsyncSend
property to
False
. Or, if you are writing to a message
monitor point via the
OutputDataPoint
property, no
response is expected. So, LNS would set the property to
True
.
