1.進(jìn)入Reboil測量位號(hào)欄；
2.輸入根位號(hào)（例如5501F）；
3.按Enter鍵或Tab鍵；
4.SMOCPro將生成完成后的測量位號(hào)（例如，5501F.PV），但之前已定義過后綴的其它所有位號(hào)（例如，閥位5501F.OP和過程輸出5501F.POV）都將使用默認(rèn)后綴/前綴；
5.你可以修改位號(hào)（如有必要）。
在你離開視圖前，UAPC變量窗口將核對(duì)你的輸入。如果有任何錯(cuò)誤，相應(yīng)欄被標(biāo)記為紅色，且標(biāo)簽上標(biāo)記紅叉。下列對(duì)話框提示你選擇單擊Yes離開視圖或單擊No保持視圖打開并修改錯(cuò)誤。
下面是UAPC變量標(biāo)簽中不同變量的屬性描述。
? 設(shè)定點(diǎn)控制（SPC）– SMOCPro向基于DCS-PID控制器的設(shè)定點(diǎn)寫輸出值。
? 直接數(shù)字控制（DDC）–SMOCPro向基于DCS-PID控制器輸出直接寫輸出值。
自動(dòng)填充DCS位號(hào)屬性
另一種迅速填寫屬性的方式是使用自動(dòng)填充功能。此功能為所有屬性自動(dòng)構(gòu)建位號(hào)名，允許位號(hào)名使用變量別名，默認(rèn)前綴/后綴和默認(rèn)后綴分隔符。在單擊窗口右上角的Auto Fill（自動(dòng)填充）按鈕后，彈出以下對(duì)話框：
用戶可以選擇覆蓋所有位號(hào)唯一屬性或僅填補(bǔ)空白項(xiàng)。
MV詳細(xì)信息
| 領(lǐng)域 | 默認(rèn)值 | 描述 |
|---|---|---|
| Alias （別名） | 工作區(qū)內(nèi)的MV變量名 | |
| Description （描述） | MV變量描述（與GMB中MV描述相聯(lián)系） | |
| Measurement Tag [t]（測量位號(hào)） | MV測量位號(hào) ? SPC: DCS控制器的PV； ? DDC:DCS控制器的輸出。 | |
| Setpoint Readback Tag [t] （設(shè)定值回讀位號(hào)） | SMOCPro寫入設(shè)定值的回讀位號(hào)。 ? SPC: DCS控制器的設(shè)定點(diǎn)； ? DDC: DCS控制器的輸出。 回讀位號(hào)用于當(dāng)MV時(shí)INACTIVE且Feed Forward（前饋）是TRUE時(shí)抑制前饋干擾。回讀位號(hào)也被用于防止因不執(zhí)行動(dòng)作而windup。 | |
| Valve Position Tag [t] （閥位位號(hào)） | 這個(gè)位號(hào)映射了基層控制器的輸出（通常是閥）。 | |
| Remote/Local Flag Tag [t] （遠(yuǎn)程/本地標(biāo)簽位號(hào)） | 此位號(hào)指示了SMOCPro寫入目標(biāo)設(shè)定值（REMOTE）或不寫入（LOCAL）。 | |
| Output Tag [t] （輸出位號(hào)） | SMOCPro控制器輸出的目標(biāo)位號(hào)。SPC: 輸入DCS控制器設(shè)定值（遠(yuǎn)程）； DDC:輸入DCS控制器的輸出（遠(yuǎn)程）。 |
原文：
- Go to the Measurement Tag cell of Reboil.
- Key in the Tag root (e.g. 5501F)
- 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. |
