Figure 20. Alarm history
Sorting
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.
History Alarms CSV Export generates history alarms log as
CSV file that can be stored.
Duration

is displayed. Once the selection is made from the drop-
down menu, pressing the REFRESH button updates the list
and then From and To timestamps get updated
accordingly.

When a Non Active alarm is acknowledged, it can be reset
which will remove it from the list to show only Active alarms
in the list.

alarms, snapshots of module parameters values.
