高級信息10-32 DriveWindow 2如果無法打開文件，則會收到一條錯誤消息，通知您寫入內(nèi)存映射文件項(xiàng)失敗。為了便于處理，符號按字母順序排列在子分支中，其名稱與子分支中的第一個符號相同。瀏覽到子分支的葉子時，符號值將顯示在瀏覽的項(xiàng)目集中。您可以通過向?yàn)g覽的項(xiàng)目集中的內(nèi)存映射文件（名稱）寫入空字符串來關(guān)閉符號表文件。關(guān)閉文件后，也可以通過在瀏覽樹窗格中雙擊Ram子分支來折疊它。10.1.3設(shè)置起始文件夾如果您無法將符號表文件保存在默認(rèn)的DriveWindow起始文件夾（安裝文件夾）中，但您有固定的位置，則可以創(chuàng)建或編輯DriveWindow快捷方式，該快捷方式將符號表文件夾定義為起始文件夾。只需右鍵單擊快捷方式圖標(biāo)并選擇屬性。高級信息驅(qū)動窗口2 10-33選擇“快捷方式”選項(xiàng)卡，在“開始位置”字段中輸入符號表文件夾的路徑，然后單擊“確定”按鈕。使用此快捷方式圖標(biāo)啟動DriveWindow時，無需為位于指定符號表文件夾中的符號表文件輸入路徑。如果您有多個但不是太多的符號表文件夾，可以根據(jù)需要為每個文件夾創(chuàng)建單獨(dú)的快捷方式。另請參閱：瀏覽參數(shù)和信號更改參數(shù)高級信息10-34 DriveWindow 2 11.從監(jiān)視器顯示器中清除垃圾使用某些操作系統(tǒng)/顯示驅(qū)動程序/顯示適配器組合，在實(shí)時繪制監(jiān)視器趨勢時可能會看到垃圾。垃圾尤其出現(xiàn)在x軸的右端。因?yàn)閷?shí)時繪圖必須快速，所以背景不能一直完全重新繪制。然而，DriveWindow版本2.12（及更高版本）中添加了定期重新繪制，定期清除可能的垃圾。在舊版本的DriveWindow中，刪除周期（以毫秒為單位）由用戶特定鍵HKEY_CURRENT_user\Software\ABB Oy\DriveWindow\Monitor下名為GarbageRemovalInterval的值確定。如果在注冊表中找不到該值，則默認(rèn)值為500毫秒。由于DriveWindow版本2.30，刪除周期（以毫秒為單位）由My Documents的DriveWare文件夾中用戶特定DW21.INI文件中名為[Monitor]的部分中名為GarbageRemovalInterval的值確定。注意，如果x軸長度大于GarbageRemovalInterval的5倍，則使用x軸長度的1/5的垃圾清除周期。垃圾清除會導(dǎo)致一些額外的處理器負(fù)載。因此，如果您的電腦沒有監(jiān)視器顯示垃圾問題，或者CPU速度慢，您可能需要更改刪除周期。十六進(jìn)制值FFFFFFFF實(shí)際上禁用垃圾清除。請注意，您所做的任何更改都將在重新啟動DriveWindow時生效。另請參閱：監(jiān)視器和數(shù)據(jù)記錄器快速監(jiān)視12.以XML格式打印和導(dǎo)出注意，本討論不涉及趨勢。趨勢打印由圖形繪圖包完成，與DriveWindow中的所有其他打印分離。此外，無法以XML格式導(dǎo)出趨勢。我們假設(shè)您對XML、XSL、XSD、CSS和MSXML有一定的了解。
Advanced Information 10-32 DriveWindow 2 If the file could not be opened, you get an error message informing you that writing to memory map file item failed. For easier handling, the symbols are arranged alphabetically in sub-branches, names of which is the same as the first symbol in the sub-branch. The symbol values are shown in the browsed item set, when you browse to the leaves of the subbranches. You can close the symbol table file by writing an empty string to the memory map file (name) in the browsed item set. After closing the file, also collapse the Ram sub-branch by double-clicking it in the browse tree pane. 10.1.3 Setting the Start-in Folder If you do not have the possibility to keep the symbol table file in the default DriveWindow start-in folder (the installation folder), but you have a constant place for them, you create or edit DriveWindow shortcut, which has your symbol table folder defined as the start-in folder. Just right-click the shortcut icon and select properties. Advanced Information DriveWindow 2 10-33 Select the Shortcut tab, enter path of your symbol table folder into the Start in field, and click the OK button. When you start DriveWindow using this shortcut icon, you do not need to enter paths for symbol table files residing in the specified symbol table folder. If you have more than one, but not too many symbol table folders, you can create a separate shortcut for each of them, if you wish.

Garbage Removal from Monitor Display With some operating system/display driver/display adapter combination garbage may be seen during real time drawing of the monitor trends. Garbage appears especially at the right end of the x-axis. Because real time drawing must be fast, the background cannot be totally repainted all the time. However, a periodic repaint has been added into DriveWindow version 2.12 (and newer), which removes possible garbage periodically. In older versions of DriveWindow the removal period in milliseconds is determined by the value named GarbageRemovalInterval under the user specific key HKEY_CURRENT_USER\Software\ABB Oy\DriveWindow\Monitor. If no such value is found the registry, the default value is 500 ms. Since DriveWindow version 2.30 the removal period in milliseconds is determined by the value named GarbageRemovalInterval within the section named [Monitor] in the user specific DW21.INI file in the DriveWare folder of My Documents. Note that if x-axis length is greater than 5 times GarbageRemovalInterval, the garbage removal period 1/5 of the x-axis length is used instead. Garbage removal causes some additional processor load.So, if your PC does not have the monitor display garbage problem, or if your CPU is slow, you may want to change the removal period. A hexadecimal value FFFFFFFF in practice disables the garbage removal. Note that any changes you make take effect just when you restart DriveWindow. See Also: Monitor and Dataloggers Fast Monitoring 12. Printing and Exporting in XML Format Note that this discussion does not concern trends. Printing of trends is done by the graphical drawing package and is separate of all other printing within DriveWindow. Also, it is not possible to export trends in XML format. We assume that you have some knowledge about XML, XSL, XSD, CSS, and MSXML.
