DrvDpCont

This class - derived from DpContainer - implements the special features of the driver data point container such as conversion or smoothing configs, which can also be defined at nodes in the data point and apply for elements at a lower level. This inheritance system of configs must particularly be taken into account for changes of attributes.

The conversion of hardware data format to WinCC OA data format (including conversion and smoothing) is also performed in this class (using convert2Ing()), as is the conversion of WinCC OA data format to hardware data format (using convert2Raw() ).

In addition, with the functions cast2Dp() and cast2HW(), a typecasting can be performed between configured data type and data point element data type.

No virtual interface functions exist for the driver-specific data point container. This class is an internal class of the general driver. It must not be overwritten by special drivers.
