P0916BV模块备件
值字段始终为空。OPC地址字段包含模板的ItemId属性，前缀为编码的源驱动器符号。源驱动器符号由两对大括号组成（作为项目OPC地址中的通道和节点），并显示模板的源驱动器属性的值。使用以下符号（n、m和o为整数）：符号含义｛｝｛｝｝默认｛n｝｛m｝固定，Ch＝n，Node＝m，而不是相对｛n｛m+o｝固定的Ch＝n，Node＝m，相对偏移＝+o｛n}｛m-o｝，固定的Ch＝n，节点＝m，相对偏移=-o｛s｝｛｝｛}已选择，不是相对｛s｝+o｝已选择，相对偏移=-o｛c｝已控制，非相对｛c｝｛+o｝受控，相对偏移=+o｛c}｛-o｝受控、相对偏移=-o参数、信号和故障4-90驱动窗口2可以在“模板属性”对话框的“源”选项卡中更改“源驱动”属性。另请参阅：使用模板9.3更改模板属性模板的属性生成规则，该规则定义实际显示的项目以及在不同情况下如何显示。通过复制添加的模板将其所有属性设置为使用默认值，即使用项目集的相应属性值。在这种情况下，如果需要，必须单独更改模板属性值。若要查看和更改模板的属性，必须查看用户项集中的模板。如果要使用“桌面”菜单，则只需选择一个模板。从桌面菜单中选择项目属性命令。请注意，当选择项目而不是模板时，相同的命令用于查看项目属性。参数、信号和故障驱动窗口2 4-91上下文菜单中包含相同的命令，您可以通过在模板上单击鼠标右键来获得该命令，您要查看或更改其属性。DriveWindow显示“模板属性”对话框。参数、信号和故障4-92驱动窗口2通过添加新项目命令添加模板时，也会显示包含属性的对话框。对话框标题为“添加新模板”。否则，该对话框与“模板属性”对话框完全相同。该对话框包含以下选项卡：•常规•源•格式•项目注意，用户项目集的“项目集属性”具有完全相同的选项卡和属性，“常规”选项卡中的“类型”和“名称”除外。其他属性的含义与“模板属性”完全相同。完成后，单击“确定”按钮。如果单击“取消”按钮，操作将被取消。请注意，如果要使用“添加新模板”对话框添加新模板，单击“取消”表示未完成添加。如果要使用“模板属性”对话框更改属性，单击“取消”意味着不会进行所请求的任何更改。还要注意，DriveWindow会记住大多数属性的最新更改，并在使用“添加新模板”对话框添加新模板时建议这些更改。这意味着在使用“添加新模板”对话框添加模板时，应始终仔细检查所有属性。参数、信号和故障DriveWindow 2 4-93添加、删除或更改模板属性被认为是工作空间中的一项主要更改。
The Value field is always empty. OPC Address field contains the ItemId property of the template prefixed to a coded source drive notation. The source drive notation consists of two pairs of curly braces (as a channel and node in the OPC Address of an item) and show the value of the Source Drive property of the template. The following notations are in use (n, m, and o are integers): Notation Meaning {}{} Default {n}{m} Fixed with Ch=n and Node=m, not Relative {n}{m+o} Fixed with Ch=n and Node=m, Relative with Offset=+o {n}{m-o} Fixed with Ch=n and Node=m, Relative with Offset=-o {s}{} Selected, not Relative {s}{+o} Selected, Relative with Offset=+o {s}{-o} Selected, Relative with Offset=-o {c}{} Controlled, not Relative {c}{+o} Controlled, Relative with Offset=+o {c}{-o} Controlled, Relative with Offset=-o Parameters, Signals, and Faults 4-90 DriveWindow 2 The Source Drive property can be changed in the Source tab of the Template Properties dialog. See Also: Using Templates 9.3 Changing Template Properties Properties of a template make rules, which define the actual item shown and how it is shown in different situations. Templates added by copying have all their properties set to use defaults, i.e., corresponding property values of the item set are used. In this case you have to change the template property values separately if needed. To be able to view and change properties of a template, you must be viewing templates in a user item set. If you are going to use the Desktop menu, you need to have exactly one template selected. Select the Item Properties command from the Desktop menu. Note that the same command is used to view item properties when an item is selected instead of a template. Parameters, Signals, and Faults DriveWindow 2 4-91 The same command is included in the context menu, which you get by clicking with the right mouse button on the template, properties of which you want to view or change. DriveWindow displays the Template Properties dialog box. Parameters, Signals, and Faults 4-92 DriveWindow 2 The dialog box containing the properties is shown also when adding a template by Add New Item command. The dialog box title is then Add New Template. Otherwise the dialog box is exactly the same as the Template Properties dialog box. The dialog box has the following tabs: • General • Source • Format • Items Note that the Item Set Properties of a user item set has exactly the same tabs and properties, except Type and Name in its General tab. Other properties have exactly the same meaning as Template Properties. When you are finished, click the OK button. If you click the Cancel button, the operation is cancelled. Note that if you were adding a new template with the Add New Template dialog, clicking Cancel means that adding is not done. If you were changing properties with the Template Properties dialog, clicking Cancel means just that any changes you requested are not made. Note also that DriveWindow remembers the latest changes of most properties and suggests them when adding a new template with the Add New Template dialog. It means that you should always check carefully all properties when adding a template by using the Add New Template dialog. Parameters, Signals, and Faults DriveWindow 2 4-93 Adding, deleting, or changing properties of templates is considered to be a major change in the workspace.
