Alarms and Filters
80-60100000-02
3–11
Bitmaps, located to the left of the alarm type names, show the current
filter settings as follows:
•
A green tick indicates that alarms of this type will be shown.
•
A red cross shows that alarms of this type are hidden.
For hidden alarms, the level at which they are hidden is also shown:
•
Three stacked boxes represent the Generic level.
•
A single box represents the Device Type level.
NB: The generic alarm list does not display the status of the filters at
device level. An alarm with a green tick on the generic list will not
necessarily appear in the Alarm windows.
3.8.2.2 Showing and Hiding alarms
To show or hide a particular alarm type, first select the level at which you
wish the filter to apply, using the Device combobox. Then select the
relevant alarm type(s) in the Device alarms list, and press the
Show or
Hide button on the left. The bitmap will change to indicate whether the
alarm is shown or hidden. You can select multiple types from the list by
using the
Ctrl and Shift keys. By default, no alarm types are filtered.
Suppose you choose to hide the
Connected alarm at Generic level. If
you then select, say, G64S in the Device combobox, you will still see a
red cross and three stacked boxes next to that alarm type. Now when
you show or hide the alarm, the single box bitmap indicates the Device
type filter status. The red cross stays because
overall, the alarm is
hidden, regardless of the Device type filter setting.
3.8.2.3 Special commands
To show or hide all alarm types for the current Device Type, or for all
Device Types, press the
Special button. This will display the Special
Alarm Filter Commands dialogue box, which contains these options.
3.8.2.4 When you have finished
When you have configured the filter you want, press
OK or Enter to
update the Alarms window.
If you do not wish to save the changes, press
Cancel or Esc.
