B11被控变量视图

被控变量数据在所选控制器的所选CV视图上显示和输入。
Control Variable（被控变量）视图有“ENG”和“OPE”两种操作模式。 以下是ENG模式的HIS窗口。

条目描述

需要由操作员和工程师输入的各个条目/参数如下。

| 条目 | 描述| 操作员模式 | 工程师模式|
| ------------- |:-------------:| -----:|
| Tag Name （位号名）| CV位号名 | R| R|
| Tag comment （位号描述）| CV的描述。| R| R|
| Remove From Control（从控制中移除）| 选择TRUE时，从控制和优化目标中删除CV； 选择FALSE时，在控制和优化目标中保持CV。 | R/W| R/W|
| Priority （优先级）| 可以根据控制要求将CV优先级定义为1到100的数。如果在实现稳态时存在控制问题，则CV通过分配的相应数值给予优先级次序。| R | R/W|
| * Set Value Type（设定值类型）| 指示CV的类型。 SETRNG表示区域控制，即CV将被控制在指定的限制（区域）内； SETPNT表示设定点控制，即CV将被控制在指定的设定点； LOLIMIT表示只有CV低限的区域控制。低限可以更改。高限也是； HILIMIT表示只有CV高限的区域控制。高限可以更改。| R| R|
| Setpoint Tracking Filter（设定点跟踪滤波）| 当SET VALUE TYPE在SETPNT（设定点）控制时，此条目有效。 TRUE表示SETRANGE HIGH / SET RANGE LOW将跟踪相应的CV值。 FALSE表示SETRANGE HIGH / SET RANGE LOW不跟踪相应的CV值。 | R | R/W|
| * Set Range High Limit（设置范围高限）| 定义了CV的高限目标值。| R/W| R/W|

B11. Control Variable View

Control Variable data are displayed and entered on the selected CV view of the selected controller.
Control Variable view has two operations such as “ENG” and “OPE” modes. Following are the HIS windows for the ENG modes.

Description of items

Various items/parameters need to be entered by operator and engineer is described below.

|Item | Description |Operator mode |Engineer mode|
| ------------- |:-------------:| -----:|
|Tag Name | CV Tag Name |R| R|
|Tag comment | CV’s Comments |R| R|
|Remove From Control| TRUE is selected to remove CV from Control and optimization Objectives. FALSE is selected to keep CV for Control and optimization Objectives. |R/W|R/W|
|Priority |CV’s Priority can be defined from 1 to 100 based on control requirement. If there is a control problem to achieve steady state then CV are given low priority by assigning numerical value accordingly. |R |R/W|
|* Set Value Type| The type of CV is indicated SETRNG indicates Zone Control i.e. CV will be controlled within specified limits (zone) SETPNT indicates set point Control i.e. CV will be controlled at specified set point. LOLIMIT indicates Zone Control with only low limit on CV. .Low limit can be changed. High limit is HILIMIT indicates Zone Control with only high limit on CV. High limit can be changed. |R |R|
|Setpoint Tracking Filter |This information is effective when SET VALUE TYPE is in SETPNT (Set point) control. TRUE indicates SETRANGE HIGH/SET RANGE LOW will track the Corresponding CV value. FALSE indicates SETRANGE HIGH/SET RANGE LOW Will not track the Corresponding CV value.| R |R/W|
|* Set Range High Limit |CV’s upper target value is defined. |R/W| R/W|
