Further information
For additional information refer to the function diagrams 7950 ff of the List Manual.
You will find additional information on the following PID controller components in the Internet
at:
● Setpoint input: Analog value or fixed setpoint
● Setpoint channel: Scaling, ramp-function generator and filter
● Actual value channel: Filter, limiting and signal processing
● PID controller Principle of operation of the D component, inhibiting the I component and
the control sense
● Enable, limiting the controller output and fault response
