_AlertClass
There is an internal data point type in order to communicate easier with alert classes which are addressed via a data point variable. There are five alert classes in WinCC OA by default. These classes are configured as _alert_class config. Additional own alert classes can, of course, be configured any time. These classes are available in the alert handling (see alert handling and alert classes).
Since the data point consists of only one element the elements are not described here. The data points whose names correspond to specific alert priorities are described instead.
