the network device containing the source object) by default. You can change this behavior by
setting the AutoRead and AutoWrite properties of the DataPoint object to False. If these
properties are set to False, OpenLNS will not update the source object every time the value
properties of the data point are updated. However, in this case, you can still use data point’s
Write method to write the value stored in these properties to the data point’s source object.
You can also use the Read method to update the value stored in these properties with the
current value of the source object.
Formatting of each data point is handled locally. As a result, formatting changes made to the
value of a data point’s source object by your application do not affect other clients that are
attempting to read the value of the same network variable, monitor point or configuration
property. This will eliminate any confusion that may be caused by formatting changes made
by another client application.
The following table summarizes the DataPoint
object.
