I use an MT8073iE panel with PLC S7 1200, project already used and working since August 2019 with the same hardware configuration.
Today, after loading the panel software, I realized that the "historical data viewer" [Data / History] displays the sampling data only during the execution of the trigger set for data sampling in the "DATA SAMPLING" settings , after which it displays only the first row with column titles.
Checked the “DATA SAMPLING” settings, tested with only one data both from PLC and with internal tag. OFFLINE simulation works but ONLINE simulation does not work.
I don't understand if it's a settings error or something?
The question is not very clear, however if you use the symbolic protocol to check that the sampled tags are within an array of equal or greater size than the number of variables sampled.
Try to verify that refresh automatically is enabled in the data history and when downloading try to select clear historical data.
But be careful the display on the simulator is not exactly the same as that of the real panel, sometimes to refresh the page you need to perform a page change and then return to the page. You have checked whether on the real panel you have the same problem.
