同樣的功能也可用于更改監(jiān)控變量并將其刪除。您可能很少使用此功能。請(qǐng)注意，您必須在項(xiàng)目集窗格中查看瀏覽類型的項(xiàng)目集、所有參數(shù)或用戶。否則，此處描述的命令將被禁用（灰色）。如果您正在設(shè)置一個(gè)空頻道，則可以使用一個(gè)項(xiàng)目作為設(shè)置的基礎(chǔ)。為此，請(qǐng)選擇項(xiàng)目集中的單個(gè)項(xiàng)目。無(wú)論如何，如果尚未選擇，請(qǐng)選擇趨勢(shì)設(shè)置窗格中的監(jiān)視器選項(xiàng)卡，然后從監(jiān)視器菜單或監(jiān)視器設(shè)置的上下文菜單中的設(shè)置變量子菜單中選擇要設(shè)置的頻道。趨勢(shì)6-34 DriveWindow 2顯示一個(gè)添加項(xiàng)目到監(jiān)視器和桌面對(duì)話框。如果您正在設(shè)置一個(gè)空頻道，并且選擇了一個(gè)項(xiàng)目作為基礎(chǔ)，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(shè)置一個(gè)空通道，但您沒(méi)有選擇要用作基礎(chǔ)的項(xiàng)目（或有多個(gè)選擇），則字段將填充通過(guò)將項(xiàng)目添加到項(xiàng)目集中而最后接受的值。如果最后接受的值為空（請(qǐng)求刪除項(xiàng)目），則必須自己填寫編輯字段。如果正在設(shè)置的頻道不為空，則當(dāng)前設(shè)置位于編輯字段中。趨勢(shì)驅(qū)動(dòng)窗口2 6-35無(wú)論如何，在名稱編輯字段中有一個(gè)描述性名稱（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(qǐng)注意，您給出的描述性名稱不需要是唯一的。如果您提供的OPC地址正確且項(xiàng)目存在，則會(huì)將其添加到瀏覽的項(xiàng)目集和您正在設(shè)置的監(jiān)視器通道中。請(qǐng)注意，它是內(nèi)部鎖定的，因?yàn)樗鞘鼙O(jiān)控的，但不是在線的，即使所使用的基礎(chǔ)是在線的。項(xiàng)目的描述性名稱也顯示在監(jiān)視器設(shè)置的通道字段中。上一項(xiàng)（如果有）將被刪除。請(qǐng)注意，在瀏覽的項(xiàng)目集中，刪除的項(xiàng)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(cuò)誤或項(xiàng)目不存在，當(dāng)您單擊“確定”時(shí)，您的電腦會(huì)發(fā)出蜂鳴聲，“將項(xiàng)目添加到監(jiān)視器和桌面”對(duì)話框?qū)⒈Ａ?。趨?shì)6-36 DriveWindow 2然而，如果您清除兩個(gè)編輯字段，這不是錯(cuò)誤，但您正在設(shè)置的頻道中已經(jīng)存在的任何監(jiān)控變量都將從監(jiān)視器中刪除（但在瀏覽的項(xiàng)目集中保持解鎖狀態(tài)）。請(qǐng)注意，移除的項(xiàng)目在項(xiàng)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(jiān)控變量的驅(qū)動(dòng)注意，為了能夠更改受監(jiān)控的變量的驅(qū)動(dòng)，您需要清除監(jiān)視器?；蛲ㄟ^(guò)使用瀏覽樹(shù)窗格來(lái)更改驅(qū)動(dòng)器，如果不是所有頻道都要更改，還可以更改瀏覽的項(xiàng)目集。要更改驅(qū)動(dòng)器：?如果尚未選擇，請(qǐng)選擇趨勢(shì)設(shè)置窗格中的監(jiān)視器選項(xiàng)卡。?在瀏覽的項(xiàng)目集中，選擇要更改其驅(qū)動(dòng)器的受監(jiān)視項(xiàng)目。如果要更改所有受監(jiān)視項(xiàng)目的驅(qū)動(dòng)器，也可以將它們?nèi)勘Ａ魹槲催x中狀態(tài)。請(qǐng)注意，如果您正在查看項(xiàng)目集窗格中瀏覽的項(xiàng)目集以外的其他項(xiàng)目集，則即使在隱藏的瀏覽項(xiàng)目集中進(jìn)行了選擇，所有受監(jiān)視項(xiàng)目的驅(qū)動(dòng)器也始終會(huì)更改。?在瀏覽樹(shù)窗格中，單擊新驅(qū)動(dòng)器以選擇它。但是，不必選擇其根。選擇其任何分支機(jī)構(gòu)即可。?最后，在監(jiān)視器菜單或監(jiān)視器設(shè)置的上下文菜單中選擇更改驅(qū)動(dòng)器命令。趨勢(shì)驅(qū)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(qū)動(dòng)發(fā)生變化。請(qǐng)注意，即使使用監(jiān)視器設(shè)置的上下文菜單，操作也會(huì)使用在瀏覽的項(xiàng)目集中所做的選擇，而不是在監(jiān)視器設(shè)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.
