同樣的功能也可用于更改監控變量并將其刪除。您可能很少使用此功能。請注意，您必須在項目集窗格中查看瀏覽類(lèi)型的項目集、所有參數或用戶(hù)。否則，此處描述的命令將被禁用（灰色）。如果您正在設置一個(gè)空頻道，則可以使用一個(gè)項目作為設置的基礎。為此，請選擇項目集中的單個(gè)項目。無(wú)論如何，如果尚未選擇，請選擇趨勢設置窗格中的監視器選項卡，然后從監視器菜單或監視器設置的上下文菜單中的設置變量子菜單中選擇要設置的頻道。趨勢6-34 DriveWindow 2顯示一個(gè)添加項目到監視器和桌面對話(huà)框。如果您正在設置一個(gè)空頻道，并且選擇了一個(gè)項目作為基礎，則兩個(gè)編輯字段都已經(jīng)有了可以編輯的值。如果您正在設置一個(gè)空通道，但您沒(méi)有選擇要用作基礎的項目（或有多個(gè)選擇），則字段將填充通過(guò)將項目添加到項目集中而最后接受的值。如果最后接受的值為空（請求刪除項目），則必須自己填寫(xiě)編輯字段。如果正在設置的頻道不為空，則當前設置位于編輯字段中。趨勢驅動(dòng)窗口2 6-35無(wú)論如何，在名稱(chēng)編輯字段中有一個(gè)描述性名稱(chēng)（您自己的），在其他編輯字段中也有一個(gè)正確的OPC地址后，您可以單擊“確定”按鈕（如果您想取消操作，則單擊“取消”）。請注意，您給出的描述性名稱(chēng)不需要是唯一的。如果您提供的OPC地址正確且項目存在，則會(huì )將其添加到瀏覽的項目集和您正在設置的監視器通道中。請注意，它是內部鎖定的，因為它是受監控的，但不是在線(xiàn)的，即使所使用的基礎是在線(xiàn)的。項目的描述性名稱(chēng)也顯示在監視器設置的通道字段中。上一項（如果有）將被刪除。請注意，在瀏覽的項目集中，刪除的項目仍保持解鎖狀態(tài)（除非您自己也鎖定了它）。如果OPC地址錯誤或項目不存在，當您單擊“確定”時(shí)，您的電腦會(huì )發(fā)出蜂鳴聲，“將項目添加到監視器和桌面”對話(huà)框將保留。趨勢6-36 DriveWindow 2然而，如果您清除兩個(gè)編輯字段，這不是錯誤，但您正在設置的頻道中已經(jīng)存在的任何監控變量都將從監視器中刪除（但在瀏覽的項目集中保持解鎖狀態(tài)）。請注意，移除的項目在項目集中仍保持解鎖狀態(tài)（除非您自己也鎖定了它）。3.4.6更改受監控變量的驅動(dòng)注意，為了能夠更改受監控的變量的驅動(dòng)，您需要清除監視器?；蛲ㄟ^(guò)使用瀏覽樹(shù)窗格來(lái)更改驅動(dòng)器，如果不是所有頻道都要更改，還可以更改瀏覽的項目集。要更改驅動(dòng)器：?如果尚未選擇，請選擇趨勢設置窗格中的監視器選項卡。?在瀏覽的項目集中，選擇要更改其驅動(dòng)器的受監視項目。如果要更改所有受監視項目的驅動(dòng)器，也可以將它們全部保留為未選中狀態(tài)。請注意，如果您正在查看項目集窗格中瀏覽的項目集以外的其他項目集，則即使在隱藏的瀏覽項目集中進(jìn)行了選擇，所有受監視項目的驅動(dòng)器也始終會(huì )更改。?在瀏覽樹(shù)窗格中，單擊新驅動(dòng)器以選擇它。但是，不必選擇其根。選擇其任何分支機構即可。?最后，在監視器菜單或監視器設置的上下文菜單中選擇更改驅動(dòng)器命令。趨勢驅動(dòng)窗口2 6-37所選頻道（或所有頻道，如果未選擇任何頻道）的驅動(dòng)發(fā)生變化。請注意，即使使用監視器設置的上下文菜單，操作也會(huì )使用在瀏覽的項目集中所做的選擇，而不是在監視器設置中。The same feature can be used also to change the monitored variable and remove it. You probably seldom use this feature. Note that you have to be viewing an item set of type browsed, all parameters, or user in the item sets pane. Otherwise the commands described here are disabled (grayed). If you are setting an empty channel, you can use an item as a base in setting. To do so, select a single item in the item set. Anyway, if not yet selected, select the Monitor tab in the trend settings pane, and select the channel you want to set from the Set Variable submenu in the Monitor menu or context menu of Monitor Settings. Trends 6-34 DriveWindow 2 An Add Item to Monitor and Desktop dialog box is presented. If you are setting an empty channel and had an item selected to be used as a base, both edit fields already have values, which you can edit. If you are setting an empty channel, but you have no item selected to be used as a base (or had multiple selections), the fields are filled with the values last accepted by adding an item into an item set. In case the last accepted values were empty (request for removing an item), you have to fill the edit fields yourself. If the channel you are setting is not empty, the current settings are in the edit fields. Trends DriveWindow 2 6-35 Anyway, after you have a descriptive name (of your own) in the Name edit field, and a proper OPC address in the other edit field, you can click the OK button (or Cancel, if you want to cancel the operation). Note that the descriptive name that you give, needs not to be unique. If the OPC address you gave is correct and the item exists, it is added into the browsed item set and to the monitor channel, which you are setting. Note that it is internally locked, because it is monitored, but not on-line, even if the base used had been on-line. The descriptive name of the item is also shown in the channel field of the monitor settings. The previous item, if there was one, is removed. Note that the removed item still stays unlocked (unless you have locked it also yourself) in the browsed item set. If the OPC address is wrong or the item does not exist, your PC beeps when you click OK, and the Add Item to Monitor and Desktop dialog box stays. Trends 6-36 DriveWindow 2 However, if you clear both edit fields, it is not an error, but any monitored variable already in the channel you are setting is removed from the monitor (but stays unlocked in the browsed item set). Note that the removed item still stays unlocked (unless you have locked it also yourself) in the item set. 3.4.6 Changing the drive of monitored variables Note that to be able to change the drive of monitored variables you need to have the monitor cleared. or Changing the drive is done by using the browse tree pane and, if not all channels are to be changed, also the browsed item set. To change the drive: ? If not yet selected, select the Monitor tab in the trend settings pane. ? In the browsed item set, select the monitored items, drive of which you want to change. If you want change the drive of all monitored items, you can also leave them all unselected. Note that if you are viewing some other item set than the browsed item set in the item sets pane, drive of all monitored items are always changed, even if there is a selection made in the hidden browsed item set. ? In the browse tree pane, select the new drive by clicking it. It is not necessary to select its root, however. Selection of any of its sub-branches will do. ? Finally, select the Change Drive command in the Monitor menu or in the context menu of Monitor Settings. Trends DriveWindow 2 6-37 The drive of the selected channels (or all channels, if nothing was selected) change. Note that even if you use the context menu of the Monitor Setting, the operation uses the selections made in the browsed item set, not in the Monitor Settings.
