Disabled = Combines multiple conditions
- No alarm assigned to the status indicator
- Alarm exists but is disabled at the source by the user. The Kaleido-X has the ability to deactivate some
alarms on the hardware itself;
- Alarm exists but was not reported yet. The software is waiting for the hardware or driver to update the
alarm.
- Alarm that has been removed (or was never added). It can happen if the alarm reference in XEdit does
not exist on the Kaleido-X. One example is if a KXI card is removed. All associated alarms will disappear and
become disabled on the Kaleido-X.
- Could not get status. Failed to communicate with device to get status. It could happen for example, if we
loose network connection. Another example is a loss of signal that would trigger a critical alarm for signal
presence but unknown for all other alarms. The freeze or black status is Disabled if the signal is not present.
Global Alarm Concepts
(Channels)
This concept involves the alarms used within a channel. In each channel we can create multiple alarm
levels, which are single alarm status entities. In many cases the user would like to know the status of all
these alarms at the same time. This Global alarm combines all the statues of each alarm to generate a
global overall status, where the most critical takes precedence. As a small example imagine we have three
alarms and two of the alarms we accept while one was in Error, then the overall alarm status would be in
Error.
Each channel will have one Global Alarm created for its alarms only. This alarm at the moment is not
configurable and is not visible to the user in the Channels tab. It is only available as a selection when use
in a Widget that supports it, like UMD or Status Alarm. It is a new entry in the drop down list that the user
can select.
As a bonus feature the user can select this alarm as a status and as well as for its text value for text status.
When any alarm is in Error this alarm's user readable named will contribute to the Global Alarm's text
value. When selected for a UMD this value will show all the text values for all alarms currently in Error.
(Status Alarm Layouts)
The Status Alarm was added to enable the user to easily use and see the status of Global Alarm, but it is
not limited to just this alarm. When any alarm is selected for this widget the status of the alarm will be
