I tried to use a Compressed Archive for this but 1. It didn't work properly (see next thread which I will post later today) and 2. I need a Standard Deviation which is not included in compressed archive (only min, max, mean and sum). In the end I need the statisticsin a Report and before that I need the statistics continously shown on a screen. I cannot use User Archive for this because this is too slow andeven if it was fast enough the systemload would be too high. Any help / suggestions much appreciated.

See the FAQs http://support.automation.siemens.com/WW/view/en/19300688 http://support.automation.siemens.com/WW/view/en/22578952 http://support.automation.siemens.com/WW/view/en/25533776
