_AlertClass

There is an internal datapoint type in order to communicate easier with alert classes which are addressed via a datapoint 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 datapoint consists of only one element the elements are not described here. The datapoints whose names correspond to specific alert priorities are described instead.


Datapoint	Description
advancedAlarm	Priority 20; yellow-gray blink color. CAME or WENT requires acknowledgement. Can be used for advanced warnings with lower priority.
alert	Priority 60; red-gray blink color. CAME or WENT requires acknowledgement. Can be used for alerting with lower priority.
danger	Priority 80; red-gray blink color. CAME or WENT requires acknowledgement. Can be used for alerting with high priority.
disturbance	Priority 100; red-gray blink color. CAME or WENT requires acknowledgement. Can be used for alerting with highest priority.
information	Priority 10; green static. Cannot be acknowledged. Can be used for operating signals that do not represent any special danger and do not require any special reactions.
warning	Priority 40; yellow-gray as blink color. CAME or WENT requires acknowledgement. Can be used for advanced warnings with higher priority.
