  • Page 116: Pid Function Block

    Appendix 17.2.7 PID Function Block A PID Function Block contains the input channel processing, the proportional-integral-deriva- tive (PID) control loop and the analog output channel processing. The configuration of the PID Block (PID controller) depends on the automation task. Simple control loops, control loops with manipulate variable feedforwarding, cascade con- trol and cascade controls with limitation in combination with another controller function block can be implemented.
  • Page 117 Appendix Derivative component: In controlled systems with long delay times, e.g. in temperature control loops, it is better to use the derivative component RATE of the controller. Using the derivative component RATE, the manipulated variable is calculated depending on the rate of change of the sys- tem deviation.
