Mr Sendha, I think if you make a new thread of your question you will get more experts to answer your question. Personally I have not useds7 PID so I cannot answer your question. But check in the Standard Library FB58 and FB59, they are said to have autotune functions. Based on other brand's PID experience, I will suggest to do autotune first to get gains then manually adjust them. Regards

Check the following topic for more information, FB58 PID auto-tune And check the manuals here: PID Temperature Control Also, Self-tuner is a valuable block to estimate the controller's parameters; PID Self-Tuner V5 PID Self Tuner: Example Adapted to Standard PID Control Regards
