自动填充DCS位号属性~Auto Fill DCS Tag Attributes

1.进入Reboil测量位号栏；
2.输入根位号（例如5501F）；
3.按Enter键或Tab键；
4.SMOCPro将生成完成后的测量位号（例如，5501F.PV），但之前已定义过后缀的其它所有位号（例如，阀位5501F.OP和过程输出5501F.POV）都将使用默认后缀/前缀；
5.你可以修改位号（如有必要）。
在你离开视图前，UAPC变量窗口将核对你的输入。如果有任何错误，相应栏被标记为红色，且标签上标记红叉。下列对话框提示你选择单击Yes离开视图或单击No保持视图打开并修改错误。

下面是UAPC变量标签中不同变量的属性描述。
 设定点控制（SPC）– SMOCPro向基于DCS-PID控制器的设定点写输出值。
 直接数字控制（DDC）–SMOCPro向基于DCS-PID控制器输出直接写输出值。
自动填充DCS位号属性
另一种迅速填写属性的方式是使用自动填充功能。此功能为所有属性自动构建位号名，允许位号名使用变量别名，默认前缀/后缀和默认后缀分隔符。在单击窗口右上角的Auto Fill（自动填充）按钮后，弹出以下对话框：

用户可以选择覆盖所有位号唯一属性或仅填补空白项。
MV详细信息

领域	默认值	描述
Alias （别名）		工作区内的MV变量名
Description （描述）		MV变量描述（与GMB中MV描述相联系）
Measurement Tag [t]（测量位号）		MV测量位号 • SPC: DCS控制器的PV； • DDC:DCS控制器的输出。
Setpoint Readback Tag [t] （设定值回读位号）		SMOCPro写入设定值的回读位号。 • SPC: DCS控制器的设定点； • DDC: DCS控制器的输出。 回读位号用于当MV时INACTIVE且Feed Forward（前馈）是TRUE时抑制前馈干扰。回读位号也被用于防止因不执行动作而windup。
Valve Position Tag [t] （阀位位号）		这个位号映射了基层控制器的输出（通常是阀）。
Remote/Local Flag Tag [t] （远程/本地标签位号）		此位号指示了SMOCPro写入目标设定值（REMOTE）或不写入（LOCAL）。
Output Tag [t] （输出位号）		SMOCPro控制器输出的目标位号。SPC: 输入DCS控制器设定值（远程）； DDC:输入DCS控制器的输出（远程）。

原文：

1. Go to the Measurement Tag cell of Reboil.
2. Key in the Tag root (e.g. 5501F)
3. Press the Enter key or the Tab key
   4.SMOCPro generates the completed Measurement Tag (for example, 5501F.PV) but also all other Tags whose suffix has been previously defined (e.g. 5501F.OP for the Valve Position and 5501F.POV for the process output) using the default suffixes/prefixes
   5.You can modify the Tags (if necessary).
   The UAPC variable window validates your inputs before you leave the view. If there is any error, the corresponding cell is flagged red and a red cross is marked on the tab. The following dialog prompts you to either click Yes to leave the view or click No to keep the view open and correct the errors.
   Below is a description of the attributes for the different variables in the UAPC Variables tabs.
    Set Point Control (SPC) – SMOCPro writes its output to the setpoint of a DCS-based PID controller.
    Direct Digital Control (DDC) – SMOCPro writes its output directly to a DCS-based PID controller output.
   **Auto Fill DCS Tag Attributes **
   Another way to quickly fill in the attributes is by using the Auto Fill function. This functionality automatically constructs the tag names for all the attributes that accept tag names using the variable Alias, default prefix/suffix and default suffix separator. After clicking the Auto Fill button on the top right corner of the window the following dialog pops up:
   Users may choose to overwrite all the tag-only attributes or to only fill blank entries.
   MV Details

Field	Default Value	Description
Alias		Name of the MV variable in the workspace.
Description		MV Variable description (linked to the MV description in GMB).
Measurement Tag [t]		Tag for the MV Measurement.• SPC: the PV of the DCS controller.• DDC: the Output of the DCS controller
Setpoint Readback Tag [t]		Readback Tag for the written setpoint from SMOCPro.• SPC: the Setpoint of the DCS controller• DDC: the Output of the DCS controller.The readback Tag is used for feed forward disturbance rejection if MV is INACTIVE and Feed Forward is TRUE. The readback Tag is also used to prevent windup due to non-implementation of moves.
Valve Position Tag [t]		This Tag maps the output of the base layer controller (usually a valve).
Remote/Local Flag Tag [t]		This Tag indicates if SMOCPro may write to the destination setpoint (REMOTE) or may not write (LOCAL).
Output Tag [t]		Destination Tag for the output of the SMOCPro controller.SPC: Enter the (Remote) Setpoint of the DCS controller.DDC: Enter the (Remote) Output of the DCS controller.
