Technical Information

To create an AlarmArea, go to Alarms → Areas. It is possible to create SubAreas by clicking on selecting an existing AlarmArea and creating a new one inside of it. AfterwardsNext, go to Alarms → Items, right-click on the column titles and headers, enable the Area column, then edit it to specify which Area and assign each AlarmItem belongs to its corresponding Area by editing the column.
Each AlarmArea has its own alarm counts, as well as methods to acknowledge and disable all connected Alarms connected to it. These fields functionalities can be associated with linked to buttons to manage Alarms. You can check these possibilities out by double-clicking this example’s components in Draw mode and looking at their Dynamics and text fields.
Additionally, Areas can be used to filter AlarmItems, making simplifying and organizing the visualization contents of AlarmViewers simpler and more organized. On . To do this, go to Displays → Draw → Modules, select an AlarmAreas component and place it on the desired display. Set the SelectedArea field to a text tag, and then apply it to the AlarmAreas through the display’s CodeBehind, like this:

public async void ApplyFilterButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
	 if(String.IsNullOrEmpty(@Tag.SelectedArea))
	 	 @Tag.AlarmFilter = "";
	 else
	 	 @Tag.AlarmFilter = @Alarm.Area[@Tag.SelectedArea].GetFilterGetFilterAsync();
}

This code

retrieves the Area selected by the user through the AlarmAreas component.

The GetFilterAsync method then generates a text filter that includes the selected Area and all of its SubAreas. This filter is

assigned to the AlarmFilter text tag

, which is applied to the AlarmViewer by double-clicking on it in Draw mode and setting its Filter field to {Tag.AlarmFilter}.
