?固定表示使用模板的名稱屬性。?從驅(qū)動器獲取意味著從驅(qū)動器讀取項(xiàng)目名稱。從驅(qū)動器中讀取項(xiàng)目名稱可能并不總是可能的。如果名稱不可用，DriveWindow將使用項(xiàng)目的OPC地址作為其名稱。參數(shù)、信號和故障驅(qū)動窗口2 4-141選擇源驅(qū)動允許您選擇從哪個(gè)驅(qū)動獲取項(xiàng)目集中的項(xiàng)目。該設(shè)置實(shí)際上是一個(gè)默認(rèn)值，可以由使用它的每個(gè)項(xiàng)集中的相應(yīng)屬性覆蓋。?固定意味著項(xiàng)目值總是從同一個(gè)驅(qū)動器獲取。您必須通過提供驅(qū)動器的通道（Ch）和節(jié)點(diǎn)（node）編號來指定其OPC地址。?在信道中，您指定OPC地址的信道號（0..9）部分。僅當(dāng)“源驅(qū)動器”為“固定”時(shí)，才會啟用（非灰色）。?在節(jié)點(diǎn)中，指定OPC地址的節(jié)點(diǎn)號（1..254）部分。僅當(dāng)“源驅(qū)動器”為“固定”時(shí)，才會啟用（非灰色）。?“選定”表示從瀏覽樹窗格中選定的驅(qū)動器或相對于該驅(qū)動器（如果選擇了“相對”）獲取項(xiàng)目值。?受控意味著項(xiàng)目值是從驅(qū)動器中獲取的，已對其進(jìn)行控制，或與之相關(guān)（如果選擇了“相對”）。?通過選擇“相對”，可以指定源驅(qū)動器相對于“固定”、“選定”或“受控”驅(qū)動器的偏移。?偏移量指定源驅(qū)動器距離“固定”、“選定”或“受控”驅(qū)動器的距離。如果未選擇“相對”或禁用“相對”（灰色），則該選項(xiàng)將被禁用（灰色）。請注意，已瀏覽項(xiàng)目的源驅(qū)動器固定為“選定”，因此已瀏覽項(xiàng)目集的“項(xiàng)目集屬性”中沒有此屬性。所有故障和所有事件類型的項(xiàng)目集沒有特定的源驅(qū)動器，因?yàn)樗鼈兪占嘘P(guān)所有連接的驅(qū)動器的信息。很少有理由選擇相對屬性。Offset屬性的值是數(shù)字。如果為正，則通過在瀏覽樹窗格中從“固定”、“選定”或“受控”驅(qū)動器向下計(jì)數(shù)驅(qū)動器來確定源驅(qū)動器。負(fù)值表示向上計(jì)數(shù)。計(jì)數(shù)完成時(shí)，打開的參數(shù)文件不被視為驅(qū)動器。如果“偏移”為零，則會像未選擇“相對”一樣進(jìn)行處理。選擇N/A Items（N/A項(xiàng)目）允許您為用戶定義的項(xiàng)目集指定如何顯示當(dāng)前源驅(qū)動器中不可用的項(xiàng)目。該設(shè)置是默認(rèn)值，可以由每個(gè)用戶定義的項(xiàng)集中的相應(yīng)屬性覆蓋。?隱藏意味著根本不顯示不可用的項(xiàng)目。?顯示表示不顯示可用項(xiàng)目，但其值顯示為。?顯示為模板表示如果項(xiàng)目不可用，則顯示模板。
? Fixed means that the Name properties of the templates are used. ? Fetch from Drive means that the names of items are read from the drive. Reading the name of an item from the drive may not always be possible. If the name is not available, DriveWindow uses the OPC Address of the item as its name. Parameters, Signals, and Faults DriveWindow 2 4-141 The selection Source Drive allows you to select, from which drive the items in the item sets are fetched. The setting is actually a default value and can be overridden by the corresponding property in each item set that uses it. ? Fixed means that the item values are always fetched from the same drive. You have to specify the OPC Address of it by giving the channel (Ch) and node (Node) number of the drive. ? In Ch you specify the channel number (0..9) part of the OPC Address. It is enabled (not grayed) only if the Source Drive is Fixed. ? In Node you specify the node number (1..254) part of the OPC Address. It is enabled (not grayed) only if the Source Drive is Fixed. ? Selected means that the item values are fetched from the drive selected in the browse tree pane, or relative to it (if you have Relative selected). ? Controlled means that the item values are fetched from the drive, control of which has been taken, or relative to it (if you have Relative selected). ? By selecting Relative you specify that the source drive is relative by Offset to the Fixed, Selected, or Controlled drive. ? Offset specifies, how far the source drive is from the Fixed, Selected, or Controlled drive. It is disabled (grayed) if Relative is not selected or is disabled (grayed). Note that the source drive for the browsed items is fixed to Selected, so the browsed item set does not have this property in its Item Set Properties. Item sets of type all faults and all events do not have a specific source drive because they gather information about all drives that are connected. Very seldom you have a reason to select the Relative property. The value of the Offset property is numeric. If it is positive, the source drive is determined by counting drives downwards in the browse tree pane from the Fixed, Selected, or Controlled drive. Negative value means counting upwards. An open parameter file is not considered to be a drive when counting is done. If Offset is zero it is handled as if Relative was not selected. The selection N/A Items allows you to specify for user defined item sets, how to display items that are not available in the current source drive. The setting is a default value and can be overridden by the corresponding property in each user defined item set. ? Hide means that not available items are not shown at all. ? Show means that not available items are shown, but their values are shown as . ? Show as Template means that the template is shown if an item is not available.
