FIGURE 66 - ADVANCED TREND SETUP SCREEN

OVERVIEW
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 pa-
rameters compared to thresholds. The triggers can be
used individually or in combination. The digital and ana-
log parameters are selected from the COMMON SLOTS
Screen (or Master Slot Numbers List in this manual).
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 Ac-
tion.
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.
