Requirement: In your project, alarms are defined in alarm groups and they are assigned to an alarm class. The following instructions are based on the example which is described in the ⮫ “Creating an Alarm Management ” chapter.
The alarm banner displays an active alarm in online mode. If there are multiple active alarms, filtering takes place by means of the filter criteria set in the alarm banner (newest for filter criterion "Priority" and most important for filter criterion "Newest"). See the instructions below for adding scroll elements in order to switch the display between multiple alarms.
