| 领域 | 默认值 | 描述 |
|---|---|---|
| Calculated Low Limit [t/v]（计算低限） | 0.0 | 根据Setpoint High/Low Limit, Valve High/Low Limit和Valve Gain Near High/Low Limit计算内部MV低限。 只有当Advanced选中时才可见。对于正/反作用控制器： |
| Incremental Value of MV [t/v] （MV增量值） | 0.0 | 下一步控制作用，即当前值的MV偏差（内核输出参数）。只有选中Advanced时才显示。 |
| Absolute Value of MV [t/v] （MV绝对值） | 0.0 | 下一步MV绝对值（内核输出参数）。只有选中Advanced时才显示。 |
| Constraint Flag [t/v] （约束标志） | 0.0 | 对于计算MV高/低限的约束行为（0：无约束；+1：高约束；-1：低约束）（内核输出参数）。只有选中Advanced时才显示。 |

| Steady State Constraint Flag [t/v] （稳态约束标签） | 0.0 | 稳态时（内核输出参数）的预测约束行为（0：无约束；+N：高约束；-N：低约束）。N值提供了约束活跃的细节，1~100：CV约束优先级；101：经济优化；111：混合比约束。只有选中Advanced时才显示。 |
| Actual MV Status [t/v] （MV实际状态） | INACTIVE | MV（内核输出参数）实际状(BAD/ACTIVE/INACTIVE)。只有选中Advanced时才显示。 |

| Field | Default Value | Description |
|---|---|---|
| Calculated Low Limit [t/v] | 0.0 | Calculated internal MV low limit based on Setpoint High/Low Limit, Valve High/Low Limit and Valve Gain Near High/Low Limit. Visible only when Advanced option is selected. For both direct and reverse acting controllers: where LoLim is computed as per the Valve Gain Near High Limit or Valve Gain Near Low Limit specification above. |
| Incremental Value of MV [t/v] | 0.0 | Next control action, i.e. the MV deviation from current value (Kernel output parameter). Visible only when Advanced option is selected. |
| Absolute Value of MV [t/v] | 0.0 | Next absolute MV value (Kernel output parameter). Visible only when Advanced option is selected. |
| Constraint Flag [t/v] | 0.0 | Constraint activity (0:Not-limited, +1:High-limited, -1:Low-limited) with respect to MV calculated high/low limit (Kernel output parameter). Visible only when Advanced option is selected. |
| Steady State Reachable Value [t/v] | 0.0 | The predicted steady state values of MVs (Kernel output parameter). Visible only when Advanced option is selected. |
| Steady State Constraint Flag [t/v] | 0.0 | The predicted constraint activity (0:Not-limited, +N:High-limited, -N:Low-limited) at steady state (Kernel output parameter). The value of N provides details on what has made constraint active, 1~100:the priority level for the CV constraints, 101: economic optimization, 111:blending ratio constraints. Visible only when Advanced option is selected. |
| Actual MV Status [t/v] | INACTIVE | The actual status (BAD/ACTIVE/INACTIVE) of MV (Kernel output parameter). Visible only when Advanced option is selected. |
NOTE: In some DCS systems, the Setpoint Readback Tag is identical to the Output Tag.
DV详情
| 名称 | 默认值 | 描述 |
|---|---|---|
| Alias（别名） | 工作区中DV变量名。 | |
| Description（描述） | DV变量描述（与GMB中的DV描述相联系） | |
| Measurement Tag [t]（测量位号） | DV测量位号名 | |
| Disconnect Flag [t/v]（断开标签） | False | 此标签(True/False)用于指示该DV的测量值是否应该被前馈干扰抑制所忽略。 (如果断开，SMOCPro将对DV使用内部预测) |
| Essential For Control [t/v]（重要控制） | False | 此标签(True/False)用于指示此DV对与其关联子控制器持续（ACTIVE）操作是否是必须的。 （见Max Time Invalid 最大无效时间） |
| Max Time Invalid [t/v]（最大无效时间） | 0 | 如果DV测量量处于INACTIVE时计时器将启动。如果计时器超过此指定值（s）且DV是重要控制，则DV的子控制器将被设为INACTIVE。 |

**DV Details **
| Name | Default Value | Description |
|---|---|---|
| Alias | Name of the DV variable in the workspace. | |
| Description | DV Variable description (linked to the DV description in GMB). | |
| Measurement Tag [t] | Tagname for the DV measurement. | |
| Disconnect Flag [t/v] | False | Flag (True/False) to indicate if the measurement of this DV should be ignored for feed forward disturbance rejection (SMOCPro will use internal prediction for the DV if it is Disconnected). |
| Essential For Control [t/v] | False | Flag (True/False) to indicate if this DV is essential for the continued (ACTIVE) operation of its associated Sub-Controller (see also Max Time Invalid). |
| Max Time Invalid [t/v] | 0 | If the DV measurement is INACTIVE a timer will start. If the timer exceeds this specified value (seconds) and the DV is Essential for Control, then the DVs Sub-Controller will be set INACTIVE. |
