Use the Dynacard Poll Interval field on the Lufkin SAMS tab to specify the frequency with which Geo SCADA Expert retrieves dynacard data from the controller.
Enter the interval in the OPC Time Format, or specify 0 to disable automatic polling.
If required, you can use the Upload Dynacard Data pick action to upload just one particular type of dynacard data (see Actions that are Specific to the Lufkin SAMS Driver).
