MVME55006E-0161工控机器人备件
通过单击趋势设置窗格中的监视器选项卡进行选择。除了监视器和数据记录器的常见设置（x轴长度、y轴最小值和最大值、y轴自适应、通道缩放）外，监视器还具有以下设置：•模式（快速或正常）•间隔（毫秒）•历史缓冲区大小（秒）•要监视的变量除非清除监视器，否则这些设置都不能更改。通用设置可以随时更改。笔记更改监视器通道的缩放比例要求从开始重新绘制监视器趋势。如果您有大量监控数据，这可能需要很长时间。所有监视器设置都保存到工作区中并从工作区中恢复。但是，请注意，还原时必须存在还原的项目。如果没有，则无法恢复，相应的通道将留空。另请参阅：监视器和数据记录器趋势设置窗格监视器设置监视器菜单上下文菜单监视器设置3.1设置监视模式您只能在清除监视器时更改监视模式。有两种监控模式：•正常模式•快速模式在正常模式下，原则上，您可以监控任何类型的项目。此模式的最小间隔为10毫秒。正常模式是您几乎始终使用的模式。在快速模式下，您只能监控驱动参数和实数或整数类型的信号。此模式的最小间隔为1毫秒。您应该避免使用此模式，因为它可能会挂断您的电脑和/或导致驱动器中的面板丢失。笔记Windows不是实时操作系统。这意味着，在实践中，即使测量周期性地进行，也不会以相等的时间间隔进行。Windows内核中的驱动器导致的负载可能会导致测量中断，其数量级为数百毫秒。这些中断可以隐藏您试图监视的现象，特别是当您的监视间隔很小时。请注意，如果您将监控间隔设置为小于10毫秒，则无法将模式从快速更改为正常。您必须首先将间隔设置为大于或等于10ms，然后才能将模式更改为正常模式。趋势驱动窗口2 6-21要更改监控模式：•如果尚未选择，请选择趋势设置窗格中的监控选项卡。•双击监视器设置窗格中的模式字段，或在监视器菜单或监视器设置的上下文菜单中切换快速模式。或模式的新值显示在监视器设置窗格中。如果模式很快，也会在监视器菜单中进行标记。如果无法更改模式（监视器未清除，或在快速模式下间隔小于10毫秒），双击“模式”字段时，电脑会发出蜂鸣声。监视器菜单中的快速模式也被禁用（灰色）。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3.2设置监视间隔监视间隔实际上是x轴绘图分辨率。如果可能，它也用作测量的周期时间。如果测量周期比监测间隔更长，则某些测量不可避免地会丢失。例如，当内核级设备驱动程序使用处理器时，可能会发生这种情况。由于测量值带有时间戳，因此监视器显示窗格中的x轴仍然显示实时。绘制值根据测量值进行估算。如何进行估计取决于在图形首选项中选择的监视器可视化方法。只有在清除监视器时，才能更改监视间隔。注意，x轴长度和历史缓冲区大小（以毫秒为单位）必须是间隔的倍数。趋势6-22驱动窗口2要更改监控间隔：•如果尚未选择，请选择趋势设置窗格中的监控选项卡。•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如果值无效，则显示错误消息
You do the selection by clicking the Monitor tab in the trend settings pane. In addition to the common settings (x-axis length, y-axis minimum and maximum, adaptation of y-axis, scaling of channels) for monitor and dataloggers, the monitor has the following settings: • Mode (fast or normal) • Interval in milliseconds • History buffer size in seconds • Variables to be monitored None of these settings can be changed unless the monitor is cleared. The common settings can be changed any time. Note! Changing of the scaling of a monitor channel requires that the monitor trends are redrawn from the beginning. If you have lot of monitored data, this can take a long time. All monitor settings are saved into and restored from a workspace. Note, however, that the restored items must exist at restore time. If not, they cannot be restored, and the corresponding channels are left empty.

There are two modes of monitoring: • Normal mode • Fast Mode In normal mode you are able, in principle, to monitor any kind of item. The minimum interval in this mode is 10 ms. Normal mode is the mode you will almost always use. In fast mode you can monitor only drive parameters and signals of type real or integer. The minimum interval in this mode is 1 ms. You should avoid using this mode, because it may hang-up you PC and/or cause panel losses in drives. Note! Windows is not a real-time operating system. It means that, in practice, even if the measurements are done cyclically, they are not done with equal time intervals. Load caused by drives in Windows kernel may cause interrupts in measurements, order of which is hundreds of milliseconds. These interrupts can hide the phenomena you are trying to monitor, especially when your monitoring interval is small. Note that if you have set the monitoring interval to less than 10 ms, you cannot change mode from fast to normal. You have to first set interval greater or equal to 10 ms, and then you can change the mode to normal. Trends DriveWindow 2 6-21 To change monitoring mode: • If not yet selected, select the Monitor tab in the trend settings pane. • Either double-click the Mode field in the monitor settings pane, or toggle Fast Mode in the Monitor menu or in the context menu of Monitor Settings. or The new value of the mode is shown in the monitor settings pane. If the mode is fast, it is also marked in the Monitor menu. If it is not possible to change the mode (monitor is not cleared, or interval is less the 10 ms in fast mode), your PC beeps, when you double-click the Mode field. Fast Mode in the Monitor menu is disabled (grayed), too.

It is also used as a cycle time of measurements, if possible. If a measurement cycle takes longer than the monitoring interval, some measurements are unavoidably dropped. This can happen, when kernel level device drivers are using the processor, for example. Because the measurements are time stamped, the x-axis in the monitor display pane still shows real time, however. The drawn values are estimated from measured values. How the estimation is done depends on the monitor visualization method selected in graph preferences. You can change the monitoring interval only when the monitor is cleared. Note that x-axis length and the history buffer size (in milliseconds) must be multiple of the interval.
