如果无法拖放，光标将在浏览树窗格中的驱动器或打开的参数文件（或其中的子分支）上方变成一个禁止符号。松开鼠标按钮将取消拖放操作。13.1.3确认请求DriveWindow要求您确认将值写入驱动器或打开的参数文件。如果确定要写入值，请单击“是”按钮。13.1.4错误消息确认写入后，DriveWindow会尝试将值写入驱动器或打开的参数文件。它跳过所有没有值的项目。例如，如果由于写保护或不存在而导致任何其他项目的写入失败，DriveWindow会发出蜂鸣声并显示错误消息。如果所有项目（有一个值）都没有错误地写入，DriveWindow不会显示任何消息。参数、信号和故障4-124 DriveWindow 2如果某些但不是所有项目都可以写入，DriveWindow会显示一条消息。请注意，DriveWindow不会告诉您哪些项目写入失败。如果这些项目都无法写入，DriveWindow会向您显示有关它的消息。另请参阅：什么是参数和信号如何恢复参数如何比较参数14.如何比较参数可以将参数文件中的可恢复参数、读/写参数、属性和应用程序属性与驱动器或其他参数文件中参数进行比较。请注意，出于安全原因，在控制某些驱动器时，不能比较任何驱动器的参数。在这种情况下，当在浏览树窗格中选择驱动器时，菜单中的命令将被禁用（灰色）。注意，信号不会被比较，除非它们实际上是写保护的可恢复参数。如果打开了参数文件，则会将其中的参数与选定驱动器中的参数进行比较。否则，如果您想比较两个参数文件，则会请求要使用的参数文件。参数、信号和故障驱动器窗口2 4-125 14.1.1将驱动器与打开参数文件进行比较要将打开参数文件中的参数与驱动器中的参数进行比较：•在上下文菜单的“参数”子菜单中选择“比较”命令，可通过在浏览树窗格中的驱动器（或其中的子分支）上单击鼠标右键获得该命令。除了使用上下文菜单，您还可以：•在浏览树窗格中选择（单击）驱动器。•从“文件”菜单的“参数”子菜单中选择“比较”命令。DriveWindow从驱动器上载所需参数。上传它们需要一段时间。光标变为沙漏，状态栏通知您上传。参数、信号和故障4-126驱动器窗口2 14.1.2将驱动器与请求的参数文件进行比较如果没有打开的参数文件，将参数文件中的参数与驱动器中的参数进行比较：•在上下文菜单的“参数”子菜单中选择“比较”命令，通过在浏览树窗格中的驱动器（或其中的子分支）上单击鼠标右键，可以获得该选项。除了使用上下文菜单，您还可以：•在浏览树窗格中选择（单击）驱动器。•从“文件”菜单的“参数”子菜单中选择“比较”命令。
If dropping is not possible the cursor turns into a forbidden sign above the drive or the open parameter file (or a sub-branch within them) in the browse tree pane. Releasing the mouse button cancels the drag and drop operation. 13.1.3 Confirmation request DriveWindow requests you to confirm writing of the values to the drive or to the open parameter file. Click the Yes button if you are sure you want to write the values. 13.1.4 Error messages After you have confirmed the writing, DriveWindow tries to write the values to the drive or to the open parameter file. It skips all items that do not have a value. If writing of any other item fails because of being write protected or does not exist, for example, DriveWindow beeps and shows you an error message. If all items (having a value) were written without errors, DriveWindow does not show any message. Parameters, Signals, and Faults 4-124 DriveWindow 2 If some but not all items could be written, DriveWindow shows you a message. Note that DriveWindow does not tell you, writing of which items failed. If none of the items could be written, DriveWindow shows you a message about it. See Also: What are Parameters and Signals How to Restore Parameters How to Compare Parameters 14. How to Compare Parameters It is possible to compare restorable parameters, read/write parameters, Properties, and Application Properties in a parameter file with the parameters in a drive or in another parameter file. Note that for safety reasons you cannot compare parameters of any drive while control of some drive is taken. The command in the menu is disabled (grayed) in this case when a drive is selected in the browse tree pane. Note that signals are not compared, unless they actually are write protected restorable parameters. If you have a parameter file open, parameters in it are compared with parameters in the selected drive. Otherwise, and also in case you want to compare two parameter files, the parameter file to be used is requested. Parameters, Signals, and Faults DriveWindow 2 4-125 14.1.1 Comparing a Drive with the Open Parameter File To compare the parameters in an open parameter file with parameters in a drive: • Select the Compare command in the Parameters submenu of the context menu, which you get by clicking with the right mouse button on the drive (or a sub-branch within it) in the browse tree pane. Instead of using the context menu you can also: • Select (click) the drive in the browse tree pane. • Select the Compare command from the Parameters submenu in the File menu. DriveWindow uploads the required parameters from the drive. Uploading of them takes for a while. The cursor turns to hour-glass and the status bar informs you about uploading. Parameters, Signals, and Faults 4-126 DriveWindow 2 14.1.2 Comparing a Drive with a Requested Parameter File To compare the parameters in a parameter file with parameters in a drive in case there is no parameter file open: • Select the Compare command in the Parameters submenu of the context menu, which you get by clicking with the right mouse button on the drive (or a sub-branch within it) in the browse tree pane. Instead of using the context menu you can also: • Select (click) the drive in the browse tree pane. • Select the Compare command from the Parameters submenu in the File menu.
