OVERVIEW
(Flash Memory Card version C.MLM.02.02.xxx
and later)
The desired data collection start/stop triggers are setup
on this screen. The trend data collection can be set to start
or stop based upon the status of up to two selected Trig-
gers. The Triggers can consist of digital events or analog
parameters compared to thresholds. The Triggers can
be used individually or in combination. The digital and
analog parameters are selected from the Common Slots
Screen (or Master Slot Numbers List in this book).
The parameter selected as the Primary Trigger is com-
pared to a value selected as the Primary Test, using the
Primary Operator as a comparator. If it is evaluated as
true, then the data collection is started or stopped (after
any selected Trigger delay) per the selected Trigger
Action.
A Secondary Trigger can be evaluated with the Primary
Trigger to start/stop data collection. The Primary to Sec-
ondary Operator is used to define the Trigger combina
-
tions required to be true to start/stop data collection. The
Secondary Trigger is setup and evaluated the same as
the Primary Trigger.
