PI within limits

Hi programmers, this is my first message here

I have a working PI program on a 0BA6 that controls an analog output 0-10 volt.

However, I want the output to be limited between 2 and 5 volt. Now I managed to do this; under 2 and above 5 volt the output is taken over and the voltage is controlled by an analog mux.

But in the background the PI controller goes to 10 volt. As the circumstances change the PI controller has to come back from 10 volt in stead of coming back from 5 volt and that takes time and is unwanted.

How can I limit the PI controller regulating only between 2 and 5 volt?

That works like a charm.

Thank you very much! 

That has one block less.

I'll keep the Mathematic Instruction however as a reminder of that function.
