# of Alarms in the Alarm Indication of TabNavigation
I would like to use the new TabNavigation in SV5.1 FP4. There I have the possibility to show the Alarm State in an AlarmIndication Symbol next to the Navigation Button.
The Problem is that the displayed number shows the # of the Alarm Priority a not the count of the active Alarms. The displayed number is confusing the operators because the process alarms have the priority’s 3-5 and the operator does not know what this number means. So this number is useless and the alarm state he can see on the color.
Is there a possibility to show the number of alarms instead of the priority of the alarm?

Of course, just change the Status Indication expression on the TabGrouping aspect.
Default is "<aspect to read info from>:PriorityLevel"
Below an example of "<aspect to read info from>:IsUnAck" which returns number if unacknowledged alarms. "IsAlarm" will return number of active alarms if that is more desirable than unacknowledged alarms.
Just notice that I did not counter the change in alarm priority color.
The system is expecting an alarm priority level, by feeding an alarm count instead the default coloring will not work properly. I assume you must create a separate Alarm Color Definition (for use by the TabGrouping aspect only) and assign it with a "static color" (red?) for all your alarms for which the tab shall present alarm count for.
Obviously your wish to show alarm count is a bit conflicting with the current intention of showing alarm priority. The tab's alarm priority coloring will only work if you reference an alarm priority level in the expression.
If your customer is OK with seeing the alarm count (but not priority level) and having to click the alarm count figure (to call the alarm list) to find the alarm priority level I guess you are OK with what I suggested above.
A future version might be even more adjustable in terms of what you can present in the alarm tabs; just be sure to feed back your suggestions to your regional ABB sales representative.
