Hello Yousafzai, which version of WinCC you are working with? Do you use archive backup? If yes, you can link this backup via Online Trend Control, if you activate "Link Backup"for your Toolbar. Please let me know, which archive settings you made. What does WinCC show to you, if you want to select a certain time? .LDF and .MDF are data base files, it's not so easy to have a "quick look into it". If should find a programm somewhere in www, which will be able to open and read it, I think you should be very careful and copy file first before open it. If you want to work on withyour .ldf or .mdfdata you could use WinCC Option Data Monitor, but this isn't free of charge. Best regards Bizur |
