Many Simple Drivers use Scanners to define how points are scanned (polled) for data using a particular protocol. For more information, see Configuring Scanners on Simple Drivers in the ClearSCADA Guide to Simple Drivers.
As with other database items, you can perform actions on scanners via pick action menus (also referred to as context sensitive menus). For more information, see Actions Associated with Scanners on Simple Drivers.
