Set Digital Output Alarms
The set digital output alarm is similar to the excitation output alarm,
except that it uses one channel from the optional digital I/O module to
serve as the controlled output. You can add the QMI digital I/O module
to your setup in the Optional Hardware view.
Generic Alarms
With this alarm type you can trigger most of the QML logger user
functions. Note that as it provides more complex setup control and very
few security checks, use it with caution, preferably only when
instructed by Vaisala personnel.
Update Timer Interval
The update timer interval is not an alarm, but it provides threshold-
controlled event interval management. You can use it, for example, to
change the report triggering interval in steps according to the measured
value. This is performed on the Advanced user level. For more
information, see section
Changing Timer Intervals on page 182 .
Creating Alarms
Create the alarms in the Select Alarms frame, which is divided into two
list boxes. The Available alarms list box lists the available alarm types.
The Name/Type list box contains two lists displaying both the names
and types of the created alarms.
To create an alarm, proceed as follows:
1. Choose the alarm type from the Available alarms list box by
clicking on it.
2. Drag the selected item into the Name/Type list box or click Add.
NOTE Choose the correct alarm type carefully because you cannot change the
type after you have created the alarm. You can only delete the alarm
and create a new one.
