Cannot get the PID FB58 function working !!!

1 post in this topic

I'm making the PID controller tuning FB58 function. But i got a problem with FB58, i don't understand why this process value (PV_IN) don't change automatically (icrease or reduce) when i set it one value. I think that when the PV_IN change automatically , then it will get the P,I,D parameter for me. Is that right ?

I watched this video and i could not get it work. Pls, can anyone give me an example about this function ?

Please see my attachment.
