Hi experts, I configured a trendview for 4 process tags with historical data logging (it stores everything on a text file). The tags get stored correctly on my USB, but when I check the trendview, the curves get drawn with value zero always (they get displayed as horizontal lines at the bottom of the trendview). Does anyone have any idea why this could be happening? Hardware: PLC: S7-1215 HMI: KTP700 Basic PN ------------------------------------------------------------------------------------------ |

Hello Check This: https://support.industry.siemens.com/cs/de/en/view/109778709 Then load the Panel again. Check the behaviour also in Simulation, does it work here? Do a Screenchange and check again the values, its because logged Tag values are not updated in an open trend veiw. only after screen loading or if you do stop and run or change the TImespan the entries of the trend are loaded again out of the log Which TIA Portal Version and Image Version in the Panel do you use?
