To access data you have to use: - WinCC ODK function BOOL TLGGetArchivDataEx ( LPCTSTR lpszArchivName, LPCTSTR lpszVarName, SYSTEMTIME* pstStart, SYSTEMTIME* pstStop, PTLG_ARCHIVDATARAW* ppTlgData, DWORD* pdwNumberOfData, DWORD* pdwFlags, PCMN_ERROR lpError ); (it is C access) - WinCC Connectivity Pack (VBS access) I have an idea! If you use WinCC later than v6.2m there is an option to save the content into CSV file. I am almost sure that it can be done automaticly (there is option to control the Table Control from the outside). Then you can access the file and read the information you want. Best regards, Svetozar Yolov
