trends visualization on multiscreen

Hi,

I have a problem regarding trends visualization. After an unprogrammed electric Zero I can only visualize one trend on upperleft screen from OS, this OS has 4 screens. Before the blackout I can visualize several trends in 4 screens.

Where can I configure the OS for visualizate more trends in the 4 screens?

Kind regards

Hello JLoBa, 

Which version of WinCC are you currently using? After your 'unprogrammed electric zero' are the other three monitors back to normal and are visualizing the runtime screen?

If only one monitor is active, have you updated your OS Project editor settings to accommodate the single monitor configuration? 

Also as additional information, in WinCC 7.4 SP1 Update 9 or 10 and above, the option of 'displaying/configuring' upto four trendgroups in a single display is possible with the standard button function in the WinCC Runtime. 

you should have backup and recovery right? restore the image, then check again?

If you want to troubleshoot now, i think u might need to check diagnose file (program file/siemens/wincc/diagnose) or compare the services between the good station and the fault station.
