twidosuite pid+autotune

Hi
I'm working with twdlmda20drt twido PLC. I can work with the pid but i can't work with autotune, i read the whole instruction sheet but it doesn't seem to work, for example I don't get what AT output setpoint is supposed to do?

See 18.3 Twido PID Quick Start Guide in the above programming guide.

thanks for the documentation but i've read this and there are 2 setpoints that are needed to be defined by user. and i dont know the difference between them.
