Do you have an example (perhaps a screenshot)? The Advanced RT should not create any diagnostic logfiles such as WinCC V7/8/Professional. Bye Murof

Please check your project to see if you have used special scripts for custom logging or changed the default logging settings in some way. If you test with a different project, you can see if the issue persists in all projects or just one. Then, you can eliminate the project as the issue. If in all projects, check that your OS is compatible and that you don't have software like anti-virus that is not compatible. Plus, make sure you have all he latest updates as any known product issues would have been solved. Thanks, Steve

The report contains data logs per minute. When the script is executed (published), WinCC Runtime generates temporary files. Is there any solution to stop WinCC from generating these temporary files? vb script: Sub ROOM_D1_REPORT() On Error Resume Next Dim strDate strDate = DatePart("yyyy", Date) & "_" & Right("0" & DatePart("m", Date), 2) & "_" & Right("0" & DatePart("d", Date), 2) Dim strTime strTime = Right("0" & Hour(Now), 2) & "h_" & Right("0" & Minute(Now), 2) & "m_" & Right("0" & Second(Now), 2) & "s" Dim url_Folder, url_File, url_FileRef, url_Filepdf url_Folder = "D:\REPORT\ROOM_D1_REPORT\" & strDate url_File = url_Folder & "\REPORT ROOM D1_" & strDate & ".xlsx" url_FileRef = "D:\REPORT_REF_FILE\ROOM_D1_REPORT.xlsx" url_Filepdf = url_Folder & "\REPORT ROOM D1_" & strDate & ".pdf" Dim objFSO Set objFSO = CreateObject("Scripting.FileSystemObject") If Not objFSO.FolderExists(url_Folder) Then objFSO.CreateFolder(url_Folder) End If If Not objFSO.FileExists(url_File) Then objFSO.CopyFile url_FileRef, url_File End If Dim objExcelApp, objWorkbook Set objExcelApp = CreateObject("Excel.Application") objExcelApp.Visible = False objExcelApp.ScreenUpdating = False objExcelApp.DisplayAlerts = False Set objWorkbook = objExcelApp.Workbooks.Open(url_File) Dim Row_Actual, Row_DataWrite, Row_HeaderPos Row_HeaderPos = 7 With objWorkbook.ActiveSheet Row_Actual = .Cells(.Rows.Count, "A").End(-4162).Row Row_DataWrite = Row_Actual + 1 .Cells(Row_DataWrite, "A") = Now Dim tempVal tempVal = Round(HmiRuntime.SmartTags("ROOM-4 DISPLAY TEMP FL"), 2) .Cells(Row_DataWrite, "B") = tempVal .Cells(Row_DataWrite, "B").NumberFormat = "0.00" End With objWorkbook.Save objWorkbook.ActiveSheet.ExportAsFixedFormat 0, url_Filepdf, 0, 1, 0 objWorkbook.Close False objExcelApp.Quit Set objWorkbook = Nothing Set objExcelApp = Nothing End Sub
