You probably already got the documentation on your pc.
Click START/SIMATIC/Documentation/English/Step7-PID control.

You will find the PID control blocks in the Standard Library.
Highlight the FB and click F1 to view help.

You have to specify your problem to get help. Show us what you have already made, and point out what does not work.
Do you understand the block diagram on page 3-4 in the document I mentioned earlier?

Here you can see FB58 active in a CFC with PLCSIM. The output from the controller is directly connected to the input. So my fake 'process' reacts spontanously, but you can see the parameters in the controller instance DB220 and that the controller works and reacts on setpoint changes. Note that the controller must be called from an interrupt OB (here: OB35)
