thepanelshop1 Posted September 24, 2013 Report Share Posted September 24, 2013 On a trend graph, pressing the "M" button allows the operator to scroll through trend history using the automatically-appearing scroll arrow buttons. But after stopping and re-starting the trending, the PLC seems to erase the previous trend data. I know that when saving to an SD card, stopping and starting the trending begins a new file. Is there a way to scroll back through the previous trend file on the graph even after a new trending "session" has begun? Quote Link to comment Share on other sites More sharing options...
