Hi everyone I am working on a project and need to show multiple historical trends (trends of past days) on a single TrendView object. (I use WinCC Flexible 2008 SP3 on Windows7 x64) For doing that, I've already read a sample project from Siemens to archive tags that we need to show in TrendView. This sample project is here. I changed it to fulfill my requirements in my own project. Now it is working and I have no problem with archiving of tags. My project archive about 70 tags in CSV files each hour (they seprated by date and hour) and the operator can select which date and time needs to watch. Due to large amount of tags, I have to place an "IO Symbolic" object to select which tag should be displayed. The operator should select date and time and one tag to display. And TrendView should display that. (I will attach a picture of this screen) But I don't know how to do it. I tried to use an internal multiplex tag and assign all 70 tags to it and show that internal tag in TrendView but it doesn't work. Also I couldn't find anything on web to help myself. Please let me know if you find a way. And yes, I am sorry for this long story. I just tried to be clear. Thank you very much |
