PLC Basics – Manual Control, Closed Loop, ON-OFF with Hysteresis
Learn about closed-loop control systems, manual control, and ON-OFF with hysteresis and we will show a PLC simulation for each type.

Consider a typical process control system. For a particular example let us look at an open tank, which supplies a process,
