Screen Message
Description
Start of Logged Data
This message displays when you have navigated to the extreme left of the
Trending Display Graph where the plotted data starts.
End of Logged Data
When you have navigated to the extreme right of the Trending Display Graph
where the plotted data ends, this message appears.
Out of Range
This displays when a logged data value is not within the minimum or
maximum range. You can view the “out of range” values on the Data Log
screen.
Setup Error
This never displays if you use the default Trending Display screens. This
message will display if the default Trending Display framework has been
modified so that a minimum value is larger than a maximum value. It also
displays when a Display module configured for Trending has not been linked
to a Data Recorder module, so there are no values to plot.
Invalid Log
This message displays whenever an invalid log value is recorded. In addition,
trend graphs cannot be viewed.
