Batch Trend Screens collect changes over time in the control block PV, SP,
MV, and other analog signals, and display them as recording meter images.
Trend data collection can be started and stopped using tag data status as the
trigger.
Collected trend data is automatically saved in a batch trend file.
Past batch data in the batch trend file can be superimposed for display on the
Batch Trend Screen during data collection, and can be output to a CSV file.
