MVME7100-0171機器人卡件,工控自動(dòng)化卡件
?固定表示使用模板的名稱(chēng)屬性。?從驅動(dòng)器獲取意味著(zhù)從驅動(dòng)器讀取項目名稱(chēng)。從驅動(dòng)器中讀取項目名稱(chēng)可能并不總是可能的。如果名稱(chēng)不可用，DriveWindow將使用項目的OPC地址作為其名稱(chēng)。參數、信號和故障驅動(dòng)窗口2 4-141選擇源驅動(dòng)允許您選擇從哪個(gè)驅動(dòng)獲取項目集中的項目。該設置實(shí)際上是一個(gè)默認值，可以由使用它的每個(gè)項集中的相應屬性覆蓋。?固定意味著(zhù)項目值總是從同一個(gè)驅動(dòng)器獲取。您必須通過(guò)提供驅動(dòng)器的通道（Ch）和節點(diǎn)（node）編號來(lái)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“源驅動(dòng)器”為“固定”時(shí)，才會(huì )啟用（非灰色）。?在節點(diǎn)中，指定OPC地址的節點(diǎn)號（1..254）部分。僅當“源驅動(dòng)器”為“固定”時(shí)，才會(huì )啟用（非灰色）。?“選定”表示從瀏覽樹(shù)窗格中選定的驅動(dòng)器或相對于該驅動(dòng)器（如果選擇了“相對”）獲取項目值。?受控意味著(zhù)項目值是從驅動(dòng)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(guò)選擇“相對”，可以指定源驅動(dòng)器相對于“固定”、“選定”或“受控”驅動(dòng)器的偏移。?偏移量指定源驅動(dòng)器距離“固定”、“選定”或“受控”驅動(dòng)器的距離。如果未選擇“相對”或禁用“相對”（灰色），則該選項將被禁用（灰色）。請注意，已瀏覽項目的源驅動(dòng)器固定為“選定”，因此已瀏覽項目集的“項目集屬性”中沒(méi)有此屬性。所有故障和所有事件類(lèi)型的項目集沒(méi)有特定的源驅動(dòng)器，因為它們收集有關(guān)所有連接的驅動(dòng)器的信息。很少有理由選擇相對屬性。Offset屬性的值是數字。如果為正，則通過(guò)在瀏覽樹(shù)窗格中從“固定”、“選定”或“受控”驅動(dòng)器向下計數驅動(dòng)器來(lái)確定源驅動(dòng)器。負值表示向上計數。計數完成時(shí)，打開(kāi)的參數文件不被視為驅動(dòng)器。如果“偏移”為零，則會(huì )像未選擇“相對”一樣進(jìn)行處理。選擇N/A Items（N/A項目）允許您為用戶(hù)定義的項目集指定如何顯示當前源驅動(dòng)器中不可用的項目。該設置是默認值，可以由每個(gè)用戶(hù)定義的項集中的相應屬性覆蓋。?隱藏意味著(zhù)根本不顯示不可用的項目。?顯示表示不顯示可用項目，但其值顯示為。?顯示為模板表示如果項目不可用，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.
