Alarms, Events, and Trends
DescendingAlarmListTime=TRUE or FALSE
TRUE sorts in descending order, FALSE sorts in ascending order. Please note that this setting only
works for projects created with or updated to InduSoft Web Studio v6.1+SP5 or later.
Click the Allow sort in runtime checkbox if you want to allow the user to change the sort order during runtime.
Columns
Click the Columns button to open the Columns dialog where you can specify display properties for columns in
the object.
Columns dialog
• The Available list contains all of the column types available for this object. The Visible list contains all of
the column types currently in use for the object.
Click the » and « buttons to move selections between the two lists.
Tip: You can configure an Alarm Control object to display recently replaced values together with
their new values. To do so, move both Value and Previous to the Visible list.
Click the Move Up or Move Down buttons to rearrange the order of columns in the Visible list.
• Use the Label and Width fields in the Properties pane to change the default column labels and widths at
runtime.
• Use the Align combo box to specify alignment (Left, Center, or Right) for the alarm message text within a
specified column.
• Click (enable) the Available during runtime checkbox to allow the user to add selected columns to the visible list
during runtime.
• Use the Key box to assign a shortcut to each column. This allows you to sort the information on the Alarm
Control object by any column, using keyboard keys instead of the mouse cursor.
When you are finished, click OK to close the Column dialog.
Note: When acknowledging an alarm, the Alarm Control object sends a message to the Alarm
task with the following information: Tag Name, Type, User and Station. This is a solution to control
acknowledged alarms from a Thin Client.
