Hi all, I'm testing SD trend functions. Plan is to save trend curves into SD card on daily basis creating new segment every day. That seems to work. On display there is a Trend from SD object and it shows the information as expected. But my headache is how to control which segment it shows by default? Currently when display is loaded it will show the oldest segment. Is there a way to make it show latest segment by default? Or even better if Trend from SD could 'remember' which segment was last displayed on it. I do know SBs 117 and 118. HW is V1040. -Mika
dtwbb posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHi I'm making program for measuring temperature from 1200C to 1600C. The program is saving data in SD trend with play-pause (append). My latest problem is that when I open SD Trend I see the oldest recording. Is there any system solution for previewing the newest data, the last recording. Thank you
