自动填充DCS位号属性~Auto Fill DCS Tag Attributes -4

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： 其中LoLim根据Valve Gain Near High Limit 或Valve Gain Near Low Limit上述规范被计算。
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 Reachable Value [t/v] （可到达稳态值）	0.0	MVs的预测稳态值（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。

注：对某些DCS系统，设定值回读位号与输出位号是相同的。

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.
