Diagnostics Filter Function
The filter function enables you to create different views on the alarm his-
tory. By default all failure types are shown, disable not wanted failure
types to narrow the history down. For each segment the complete alarm
history list can be exported.
The failure types are sorted within the Alarm Type DropDown menu in
four categories as you can see on figure 8.5:
•
filters for the system specific alarms,
•
filter for the segment specific alarms,
•
filters for the field device specific alarms
•
and common filters, to choose non, all or only the current
present alarms of the system, segment and field device alarms.
If any field device specific alarm filter is set, you can further reduce the
view onto specific field devices within the Address Filter Dropdown
menu.
The Filter On/Off button activates or deactivates the preset filtered view.
The supervised signal level has violated the preset maintenance limit
value and a Maintenance alarm occurred on 10.07.2006 at 22.02.52

The former occured Maintenance alarm at address 246 is gone on
10.07.2006 at 22.02.52 o'clock.
