PLC is basically a specialized personal computer that connects to the physical globe. It does so via sensors, switches, buttons and other inputs. Briefly, primarily based upon the state and values of the inputs and the program within it, outputs are turned on and off. Or within a range among on and off, to manage things for hot, cold, slow or fast, and so forth...you get the concept?

The Programmable Logic Controller was actually an improvement more than old relays, cams and drums that would sequence machine operations. I bet you did not already know this considerably when you started reading this post. Changing machine operation would entail comprehensive rewiring of the sequence circuits.
