WICC can add real-type alarm variables. The method of creation is: create an internal variable "test_warning" and select "INT" as the variable type (the discrete alarm variables in WinCC flexible software can only recognize INT type with WORD type).

Create discrete alarm variables.

Alarm management---Discrete alarm---Then enter the alarm text, select the alarm number, and alarm category;----Select the trigger variable as the "test_warning" created in the previous step and set the trigger bit to "0".

The BOOL type variable representing the first bit in the "INT" type variable "test_warning" is used as the trigger bit of the discrete alarm (similar to M1.0 in MW0).

The method to create an alarm view is:

Select "Alarm View" in "Enhancement Object"----Drag it into the screen----Click "Alarm View" -----General, you can set the alarm display.

Alarm category settings display (error, alarm, system) alarms. When pending alarms are checked, the currently active alarms will be displayed; when undetermined alarms are checked, alarms that need to be confirmed but have not been confirmed will be displayed.

After the alarm event is checked, all alarms will be displayed; after the alarm record is checked, all archived alarms will be displayed.
