| Field | Default Value | Description |
|---|---|---|
| Valve Gain Near High Limit [t/v] | 1.0 | Value of the valve-to-setpoint gain near the Valve High Limit. SMOCPro uses this value in the calculations of the Calculated High and Low Limits (see below). ? SPC: For direct acting controllers (increasing the setpoint with the controller in automatic increases the valve position), the gain must be positive. For reverse acting controllers (increasing the setpoint with the controller in automatic decreases the valve position), the gain must be negative. ? DDC: Must be set to 1.0 ? For direct acting controllers: ? For reverse acting controllers: IMPORTANT NOTE: Please refer to the section below entitled “Discussion about the Valve Gain Near High- and Low Limits—dSPdV” for a more complete discussion and explanation regarding these concepts. Our recommendations are also given in this section. |

| Feed forward [t/v] | True | Flag (True/False) to indicate whether the Setpoint Readback of this MV should be used for feed forward disturbance rejection when the MV is INACTIVE. |
| Setpoint High Limit [t/v] | 10000000.0 | DDC: Must be identical to Valve High Limit. |
| Setpoint Low Limit [t/v] | -10000000.0 | Minimum limit for the value written to the MV Output Tag. DDC: Must be identical to Valve Low Limit. |
| Setpoint High Entry Limit [t/v] | 10000000.0 | This value defines the highest value allowed for SetPoint High. |
| Setpoint Low Entry Limit [t/v] | -10000000.0 | This value defines the lowest value allowed for SetPoint Low. |
| Valve High Limit [t/v] | 100.0 | High limit for the Valve Position. This is used in SMOCPro to calculate internal setpoint limits. Valve High Limit must be greater than Valve Low Limit, regardless of whether the controller is direct or reverse acting. |
| Valve Low Limit [t/v] | 0.0 | Low limit for the Valve Position. This is used in SMOCPro to calculate internal setpoint limits. Valve Low Limit must be less than Valve High Limit, regardless of whether the controller is direct or reverse acting. |
| Essential For Control [t/v] | False | Flag (True/False) to indicate if this MV is essential for the continued (ACTIVE) operation of its sub-controller (see Max Time Off Control). |
