DR2-DPM-PCU工控機器人備件
（趨勢顯示窗格）用于以圖形格式顯示趨勢。監視器和數據記錄器共享這些窗格。趨勢設置窗格包含兩個(gè)選項卡，用于選擇是顯示、更改和控制監視器還是當前選定的數據記錄器。選擇監視器后，數據記錄器設置和趨勢將被隱藏，其控件將被禁用。趨勢6-4驅動(dòng)窗口2選擇數據記錄器后，監視器設置和趨勢被隱藏，其控制被禁用。所有數據記錄器共享數據記錄器窗格。通過(guò)在瀏覽樹(shù)窗格中選擇驅動(dòng)器來(lái)選擇當前數據記錄器。如果驅動(dòng)器有兩個(gè)數據記錄器，則在瀏覽樹(shù)窗格、數據記錄器菜單或數據記錄器顯示的上下文菜單中選擇驅動(dòng)器數據記錄器?；蚧蛉绻寗?dòng)器有兩個(gè)以上的數據記錄器，則選擇驅動(dòng)器數據記錄器的方式與選擇兩個(gè)數據記錄器的方法相同。但是，菜單顯示的是下一個(gè)數據記錄器，而不是數據記錄器2。單擊下一數據記錄器會(huì )將驅動(dòng)器數據記錄器選擇移至下一數據記錄儀。請注意，最后一個(gè)數據記錄器的下一個(gè)是第一個(gè)數據記錄器?；蜃⒁?，所有數據記錄器設置和顯示都是特定于數據記錄器的。因此，例如，當您更改數據記錄器設置時(shí)，它僅涉及當前選定的數據記錄器。保留所有其他數據記錄器的設置。您可以從數據記錄器顯示窗格標題中顯示的OPC地址驗證當前選定的數據記錄器。如果驅動(dòng)器有多個(gè)數據記錄器，標題中的DL1、DL2等將顯示哪個(gè)記錄器。趨勢驅動(dòng)窗口2 6-5除了查看趨勢，您還可以打印和導出趨勢。1.1.1監視器在您的電腦中運行并收集數據。通過(guò)從驅動(dòng)器中循環(huán)讀取受監控的項目來(lái)完成收集。這些項目可以位于不同的驅動(dòng)器中。當監視器運行時(shí)，這些值將實(shí)時(shí)繪制在監視器顯示窗格中。如果暫停監視器，監視器顯示窗格的更新將停止，但值仍在后臺收集。當您命令監視器繼續時(shí)，將繪制暫停期間收集的值。筆記Windows不是實(shí)時(shí)操作系統。這意味著(zhù)，在實(shí)踐中，即使測量周期性地進(jìn)行，也不會(huì )以相等的時(shí)間間隔進(jìn)行。Windows內核中的驅動(dòng)器導致的負載可能會(huì )導致測量中斷，其數量級為數百毫秒。測量值由DriveOPC標記時(shí)間。然而，如果假設測量間隔恒定，則圖形繪制包只能繪制。因此，繪制的點(diǎn)實(shí)際上是根據測量值估計的。如何進(jìn)行估計取決于在圖形首選項中選擇的監視器可視化方法。1.1.2數據記錄器數據記錄器駐留在驅動(dòng)器中。數據由驅動(dòng)器收集?？梢酝ㄟ^(guò)特定的停止命令或驅動(dòng)器中的觸發(fā)條件變?yōu)檎鎭?lái)停止收集。除影響數據記錄器顯示的數據記錄器設置（x軸長(cháng)度、y最小值和最大值、縮放）外，所有其他數據記錄器設置都保留在驅動(dòng)器中。即使驅動(dòng)器沒(méi)有電源，它們也會(huì )保存在驅動(dòng)器中。然而，當上傳數據記錄器時(shí)，DriveWindow中的當前設置被凍結，因此設置顯示上傳趨勢的設置。無(wú)法實(shí)時(shí)查看數據記錄器趨勢。
The lower right pane, trend display pane, is used to display the trends in graphical format. The panes are shared by the monitor and the dataloggers. The trend settings pane contains two tabs, which you use to select, whether to show, change, and control the monitor or the currently selected datalogger. When you have selected the monitor, datalogger settings and trends are hidden and its controls are disabled. Trends 6-4 DriveWindow 2 When you have selected the datalogger, monitor settings and trend are hidden and its controls are disabled. The datalogger panes are shared by all dataloggers. The current datalogger is selected by selecting the drive in the browse tree pane. If the drive has two dataloggers, the drive datalogger is selected either in the browse tree pane, from the Datalogger menu, or from the context menu of Datalogger Display. or or If the drive has more than two dataloggers, the drive datalogger is selected the similar way as in the case of two dataloggers. However, a menu shows Next Datalogger instead of Datalogger 2. Clicking of Next Datalogger moves the drive datalogger selection to the next datalogger. Note that the next datalogger of the last one is the first datalogger. or Note that all datalogger settings and displays are datalogger specific. So, when you change a datalogger setting, for example, it concerns the currently selected datalogger only. Settings of all other dataloggers are preserved. You can verify the currently selected datalogger from the OPC address shown in the title in the datalogger display pane. If a drive more than one dataloggers, DL1, DL2, etc. in the title indicate, which of the loggers is shown. Trends DriveWindow 2 6-5 In addition to viewing the trends, you can also print and export trends. 1.1.1 Monitor Monitor runs and collects data in your PC. Collecting is done by reading cyclically the monitored items from the drives. The items can reside in different drives. The values are drawn in the monitor display pane in real time, when the monitor is running. If you pause the monitor, updating of the monitor display pane is ceased, but the values are still collected in the background. The values collected during pause are drawn, when you command the monitor to continue. 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 are hundreds of milliseconds. The measured values are time stamped by DriveOPC. The graphical drawing package, however, is able to do the drawing only, if the measurement interval is assumed to be constant. Thus, the drawn points are actually estimated from measured values. How the estimation is done depends on the monitor visualization method selected in graph preferences. 1.1.2 Dataloggers Dataloggers reside in drives. Data is collected by the drive. Collecting can be stopped by either a specific stop command or by a triggering condition becoming true in the drive. All other datalogger settings than those affecting the datalogger display (x-axis length, y minimum and maximum, scaling) are preserved in the drive. They are preserved in the drive even when it has no power. However, when a datalogger is uploaded, the current settings in DriveWindow are frozen, so the settings show the settings of the uploaded trend. It is not possible to view datalogger trends in real-time.
