Hello, Our clients want to be able to call a trend by simply chosingtag and date, for example a year back. I tried to solve this problem by creating log archives in.csv file for each day.With a buttonin WinCC flexible Iopen aprogram -openoffice calc (similar to excel) and there I use scriptsso that whenour client choose a date anda tag a new sheet is generated holding tag values for thatday andfrom these values I can make a trend in calcbut this solution is not very reliable. Can someone, please, tell me how can I do this in WinCC flexible. I have checked this FAQ: http://support.automation.siemens.com/WW/view/de/22726112and this thread: how can create an archive trend with DATE selectionbut withthe solution it offersI can only display tag values for aspecific moment. How could I make a trend for the dayfrom these values. Thank you in advance. Best Regards. |
