Hi

I have to make a PID controler in STEP7 (ladder) that is supposed to control the flow on the tube by opening or closing the valve.

Does anyone have some advice how t omake simple PID controller of my own?

If not can you tell me which of the predefined PID functions is the best for this use?

Best regards

 Check the attached manual for PID designing for standard PID control

Hello

Depends on which PLC / software that you are using.

If using SIMATIC Manager then document provided by AMAZINGAHMED would be useful for you.

More details at :

Where can you find descriptions and examples of PID control with FB 41, FB 42 and FB 43, and SFB 41, SFB 42 and SFB 43?

However if you are using TIA portal :

Example Project for PID Professional

For S7-1200 :

PID Control with PID_Compact (S7-1200)

Hope this helps
