Cre ating Trend Dis plays
The Trend Display Object is used to sample the data in a single or multiple 16-bit PLC registers and plot this data on
a time graph. You can configure the Trend Display as a single page or with multiple pages that can be viewed by
scrolling through the pages. The sampling rate and number of plots per page can be customized per trend graph.
You can display a maximum of 16 channels with varying colors to distinguish the channels. Finally, a hold feature
allows you to ‘freeze’ the graph and/or clear the graph.
