PID Block – Typical Uses

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.
