be set to 0.
inputDp The DataPoint object containing the
network variable monitor point update.
The InputDp parameter's AutoRead and
AutoWrite properties are set to False.
outputDp A DataPoint object that allows a
response to be sent if the update is a
request/response message.
The OutputDp parameter's AutoWrite
property is set to True; therefore, it will
be sent as a response when you write to
this DataPoint object.
srcAddr The SourceAddress object indicating the
source device of the network variable
monitor point update.
Added to API LNS Release 3.0.
ILcaProgressListener
The ILcaProgressListener interface can be added to an application to enable it to receive
database validation updates directly through the interface, as opposed to through the Object
Server. A database validation is initiated when the Network.Validate method is called.
If an object that implements the ILcaProgressListener interface is supplied to the function as
the progressCallback argument, it enables the object to receive updates from that database
validation process directly with the ProgressUpdate method. Otherwise, the update events
from the process will need to be received through the Object Server via the
OnDbValidationEvent event.
Note: If you are programming in Visual Basic, you should implement this as a
_DLcaProgressListener interface. For Visual C++ and all other development environments,
implement this as the ILcaProgressListener interface.
The following table summarizes the ILcaProgressListener interface .
Description Allows an application to receive database validation updates
directly through the interface.
