UFC721BE101备件模块
•双击监视器设置窗格中的间隔（ms）字段，或在监视器菜单或监视器设置的上下文菜单中选择间隔命令。或“间隔（ms）”对话框，其编辑字段中显示当前值。编辑或输入新的（整数）值，然后单击“确定”。如果要取消操作，请单击“取消”按钮。新值显示在监视器设置窗格中。间隔有限制：•值必须是大于零的整数。•该值不能大于当前x轴长度（以毫秒为单位）。•如果监控模式正常，该值必须至少为10。•与x轴长度相关的值不得太小，即x轴长度（毫秒）除以该值不得超过32700。•x轴长度（以毫秒为单位）必须是该值的倍数。例如，如果x轴长度为1秒，则间隔3ms是不可接受的。然后必须固定x轴长度或使用其他间隔。趋势驱动窗口2 6-23如果该值无效，单击确定按钮时将显示错误消息。您必须确认错误消息并编辑无效值或取消操作。如果监控模式正常，并且您输入的值小于10，则单击“确定”按钮时会显示错误消息。您必须确认错误消息，将值更改为至少10或取消操作。趋势6-24 DriveWindow 2如果您输入的值因当前x轴长度和/或历史缓冲区大小而不可接受，您可以选择固定x轴长度或历史缓冲大小。如果单击“是”，则接受间隔，但x轴长度和/或历史缓冲区大小也会更改。另请参阅：通用趋势设置恢复默认设置设置监视器监视器和数据记录器监视器设置监视器菜单监视器设置的上下文菜单3.3设置历史缓冲区大小监视器将数据收集到历史缓冲区中。历史缓冲区可以收集比屏幕上显示的数据更多的数据。当监视器暂停或停止时，可以在监视器显示窗格中滚动历史缓冲区中的数据。当历史缓冲区填充时，将忽略最旧的数据。只有在清除监视器时，才能更改历史缓冲区大小。请注意，历史缓冲区大小必须是间隔的倍数。趋势驱动窗口2 6-25要更改历史缓冲区大小：•如果尚未选择，请选择趋势设置窗格中的监视器选项卡。•双击监视器设置窗格中的历史缓冲区字段，或在监视器菜单或监视器设置的上下文菜单中选择历史缓冲区命令。或显示“历史缓冲区”对话框，其编辑字段中显示当前值。编辑或输入新的（实际）值，然后单击“确定”。如果要取消操作，请单击“取消”按钮。
• Either double-click the Interval (ms) field in the monitor settings pane, or select the Interval command in the Monitor menu or in the context menu of Monitor Settings. or An Interval (ms) dialog box is presented with the present value shown in its edit field. Edit or enter a new (integer) value and click OK. If you want to cancel the operation, click the Cancel button. The new value is shown in the monitor settings pane. There are restrictions about the interval: • The value must be an integer greater than zero. • The value cannot be bigger than the current x-axis length in milliseconds. • If monitoring mode is normal, the value must be at least 10. • The value must not be too small related to x-axis length, i.e., x-axis length in milliseconds divided by the value must not exceed 32700. • X-axis length in milliseconds must be multiple of the value. For example, if x-axis length is 1 second, interval 3 ms is not acceptable. You must then either fix the x-axis length or use another interval. Trends DriveWindow 2 6-23 If the value is invalid, an error message is displayed, when you click the OK button. You have to acknowledge the error message and edit the invalid value or cancel the operation. If the monitoring mode is normal and you have entered a value less than 10, an error message is displayed, when you click the OK button. You have to acknowledge the error message change the value to at least 10 or cancel the operation. Trends 6-24 DriveWindow 2 If you have entered value that is not acceptable because of the current x-axis length and/or history buffer size, you have the option to fix the x-axis length and/or the history buffer size. If you click Yes, your interval is accepted, but the x-axis length and/or history buffer size is changed, too. See Also: Common Trend Settings Restoring Default Settings Setting Monitor Monitor and Dataloggers Monitor Settings Monitor Menu Context Menu of Monitor Settings 3.3 Setting History Buffer Size The monitor collects data into a history buffer. History buffer makes it possible to have more data collected than fits on the screen. The data in the history buffer can be scrolled in the monitor display pane when the monitor is paused or stopped. When the history buffer fills, the oldest data is disregarded. You can change the history buffer size only when the monitor is cleared. Note that the history buffer size must be multiple of the interval. Trends DriveWindow 2 6-25 To change the history buffer size: • If not yet selected, select the Monitor tab in the trend settings pane. • Either double-click the History Buffer (s) field in the monitor settings pane, or select the History Buffer command in the Monitor menu or in the context menu of Monitor Settings. or A History Buffer (s) dialog box is presented with the present value shown in its edit field. Edit or enter a new (real) value and click OK. If you want to cancel the operation, click the Cancel button.
