Batch Trend Screens Section 4-10
• The trend data collection cycle and maximum save time in a Batch Trend
Screen are shown in the following table.
Note 1. The collection cycle is set using the CRT Builder Dialog Box (Batch Trend
Screen) from the Builder Window. For details on collection cycle settings,
refer to
5-5-2 Overview of Screen Registration .
2. Depending on the number of combined function blocks and the model of
Loop Controller that is connected, it may not be possible to collect the data
within the collection cycle that is set.
If the data is displayed on a graph under these conditions, the data will be
updated with the same values as for the previous collection. To remedy this
situation, take measures such as lengthening the collection cycle interval.
