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詳情
名稱 | 默認值 | 描述 |
---|---|---|
Alias(別名) | 工作區(qū)中DV變量名展箱。 | |
Description(描述) | DV變量描述(與GMB中的DV描述相聯(lián)系) | |
Measurement Tag [t](測量位號) | DV測量位號名 | |
Disconnect Flag [t/v](斷開標簽) | False | 此標簽(True/False)用于指示該DV的測量值是否應該被前饋干擾抑制所忽略旨枯。 (如果斷開,SMOCPro將對DV使用內部預測) |
Essential For Control [t/v](重要控制) | False | 此標簽(True/False)用于指示此DV對與其關聯(lián)子控制器持續(xù)(ACTIVE)操作是否是必須的混驰。 (見Max Time Invalid 最大無效時間) |
Max Time Invalid [t/v](最大無效時間) | 0 | 如果DV測量量處于INACTIVE時計時器將啟動攀隔。如果計時器超過此指定值(s)且DV是重要控制,則DV的子控制器將被設為INACTIVE栖榨。 |

**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. |
