Hi, guys, how’s going?
I added one “Trend Object” on screen A in PanelView Plus 1500. Then configured “Refresh Rate”, “Buffer” ……and set up X-Axis time span to 3 Hours.
Now the issue is: if HMI stays on screen A, the trend runs well.
But after 36 minutes (around), as long as I switch to another screen, then change back to screen A. The trend always goes back to 36 minutes (around) point, then starts to trend from that point/time.
Could you help me figure it out?
Thanks a lot.
