IPIDController with a feedback loop
The following function block diagram includes a feedback loop for the
manipulated value that prevents excessive overshooting by providing a minimum
and maximum value for the MV.
Example: How to add a UDFB to a PID program
You can add UDFBs outside the main program to perform specialized functions
such as converting units or transferring values.
Transfer the auto-tune gain value
This UDFB transfers the Autotune gain value to My_GainTransfer so it can be
used by the controller.
