Perform Diagnostic Trending
The diagnostic trending operation of screens allows you to capture
the relationships of a number of parameters over a period of time.
Within this operation you will:

Define the Parameters to which the Trend Apply

Define the Trigger Condition to Begin the Trend

Define the Sampling Rate and position of the Trigger

View the results of the Trend
You will access the Diagnostic Trend operation from the Top Level
Menu by pressing the [F9] key. This results in the display of the
screen shown in Figure 3.79.
Figure 3.79 – Diagnostic Screen
From this screen, additional screens are accessible to perform the
diagnostic trending functions. The screen shows the current status of
the trend, (Unprogrammed, Running, Triggered, Stopped). If a
trigger has been defined, the trigger parameter, its trigger condition
and the type of trigger will be displayed.
If data has already been captured, a time stamp indicating the last
time the given trigger has occurred. This captured data can be
viewed by pressing the [F9] softkey.
When a trigger has been defined, and is currently "Stopped", it can
be re-started by pressing the [F7] key. If the status is "Running", the
user can force the trigger to occur by pressing the [F2] key. Note
that in doing so, that the trigger condition did not actually occur, but
all data buffers can be viewed as if the condition had occurred.
To define a trend, press the [F8] key to display the setup screen,
shown in Figure 3.80.
