One more, pay attention to setup single sement dimension, could afflict station performance when load data from archive... at the end, if you need store data in safe location you have to look for Storage Plus maybe (it's addon) Regards

This operation will clear WinCC online historical data. N.B.: you have to stop runtime to perform this operation Regards
