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 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 combi -
nations required to be true to start/stop data collection.
The Secondary Trigger is setup and evaluated the same
as the Primary Trigger.
Entry fields are as follows:
If Primary Trigger
Is Primary Operator Primary Test
Primary to Secondary Operator
Secondary Trigger

Then Trigger Action the Data Collection
With a delay of Trigger Delay
After the desired Triggers are set, the START key on
the TREND Screen must be manually pressed before
the triggers will be evaluated. While waiting for the
triggers to start or stop data collection, a status message
is displayed in the upper right corner of the TREND
Screen describing the pending action.
