Summary Determines the current state of the value stored in the
OpenLNS database for the ConfigProperty object.
In some cases, the stored value for a configuration property

device when the data point is
created.
2. Set the SourceOptions property of
the newly created DataPoint to
lcaDataSourceOptionsDatabase

3. Call the Write method to set the
value from the device in the
OpenLNS database.
Alternatively, you can load all
unknown configuration property
values for the device into the
