Alarm filters
For alarm controls such as AlarmList, filters can be activated that only allow certain alarms to be displayed in the control.
The properties for configuring the filters can be found in the Properties window in the "AlarmFilter" category.
DesiredClasses
Filters by alarm class. Only alarms of the specified alarm class are displayed in the control element. If several classes are specified, the alarm class names must be separated by a semicolon. No specification means that alarms of all classes are displayed.
DesiredGroups
Filters by alarm group. Only alarms in the specified alarm group are displayed in the control element. If several groups are specified, the alarm group names must be separated by a semicolon. The specification of a superordinate group automatically includes all subordinate groups. The specification of a subordinate group must always contain the complete path of all superordinate group names separated by dots. No specification means that alarms of all groups are displayed.
DesiredStates
Filters by alarm status. Only alarms in the specified states are displayed in the control. If you want to select multiple alarm states, call up the advanced options of the property and select Custom expression... from the menu. In the text field, enter the state identifiers separated by commas (e.g. "Active", "ActiveAck") and press Enter.
The specification "None" means that all statuses are displayed.
MaxPriority, MinPriority
Numerical values that together specify the limits for the priority range of the displayed alarms. The value -1 means that alarms are not filtered by priority.
