FIGURE 50 - ADVANCED TREND SETUP SCREEN
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
Triggers. The Triggers can consist of digital events or
analog parameters compared to thresholds. The Trig-
gers 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 (af-
ter any selected Trigger delay) per the selected Trigger
Action.
A Secondary Trigger can be evaluated with the Prima-
ry Trigger to start/stop data collection. The Primary to
Secondary Operator is used to define the Trigger com-
binations required to be true to start/stop data collec-
tion. The Secondary Trigger is setup and evaluated the
same as the Primary Trigger.
