Gain - This field indicates the gain used in the PID algorithm. Click this field to enter a new value.
Reset - This field indicates the integral time constant used in the PID algorithm. Click this field to enter a new value.
Rate - This field indicates the derivative time constant used in the PID algorithm. Click this field to enter a new value.
PV Filter TC - This field indicates the PV filter time constant in seconds. Click this field to enter a new value.
SP Filter TC - This field indicates the SP filter time constant in seconds. Click this field to enter a new value.
SP Rate Dn - This field indicates the maximum negative change to the WORKING_SP in engineering units that are allowed per second. Click this field to enter a new value. A value of 0.0 indicates that no rate limiting will be done.
SP Rate Up - This field indicates the maximum positive change to the WORKING_SP in engineering units that are allowed per second. Click this field to enter a new value. A value of 0.0 indicates that no rate limiting will be done.
Structure - This field displays a description of the selected control algorithm's structure (that is, whether proportional and derivative action is on error or PV).
Beta - This field indicates the fraction of proportional action taken on error versus PV. The valid input range is 0.00 to 1.00. This field is visible whenever STRUCTURE is set to Two Degrees of Freedom Controller.
Gamma - This field indicates the fraction of derivative action taken on error versus PV. The valid input range is 0.00 to 1.00. This field is visible whenever STRUCTURE is set to Two Degrees of Freedom Controller.
IDeadband - The integral deadband. When the error (WORKING_SP minus PV) is less than this value, integral action stops.
Bias - This value is visible (in place of IDeadband) whenever the Structure is PD or P-D.
FF Gain - This field indicates the gain used in the feedforward algorithm. Click this field to enter a new value. This field is visible whenever FF_ENABLE is True.
Adaptive Mode - This area shows the Actual and Target modes. Click the ellipsis button to change the Target mode.
