Data for plotting comes from the Trend Plot Database file, which
automatically records the values of all process variables and certain
other parameters for all the controllers on the network. This data is
used to generate graphs on the Trend Plot Screen. Data can be
exported from the database to a tab-delimited, text file that can be
imported into most spreadsheet or database programs.
Old data is automatically deleted from the trend plot database in
order to keep the hard drive from filling up. You can set the length of
time for data to be kept (
System menu > Preferences > Trend Plot
tab).
The Trend Plot Database can plot the values from several parameters (
Trend Plot > Graph).
