You can use the PID block to:
- Perform Gap Action control in pH control processes.
- Provide feedback control.
- Provide feed-forward control.
- Provide anti-reset windup capability to ensure that the controller output does not get saturated under conditions of windup.
- Execute bumpless transfers by making the set point equal to the measurement (balancing) when an operator switches the block from Manual to Automatic mode.
- Generate alarms on set point deviations.
- Process other blocks through the Next Block field.
