The alarm history screen displays the history of alarms
recorded by the primary microprocessor (See
).
Sort History Items
The alarm history list can be sorted by any column in
ascending or descending order by tapping the
corresponding column heading. The triangle that
appears next to the heading indicates which column is
being sorted and the direction of sorting.
Sorting is applied to the alarm time column in
ascending order by default, which is indicated when
the triangle is pointing up. Ascending order for the
alarm time column requires that earlier records appear
on the list first. For all other columns, alphabetical
sorting applies.

alarm history is displayed. Once the selection is made
from the drop-down menu, pressing the REFRESH
button updates the list and the ‘From’ and ‘To’
timestamps will update accordingly.

Tag Value
