Hello everyone, I have a question: is the PID in PLC300 of positive feedback or negative feedback? How can one determine this? Could some expert please help answer it? Thank you.

Positive and negative feedback are determined by the characteristics of various components in the control loop; to determine whether it is positive or negative feedback, it is necessary to analyze the entire control loop.
