A programmable logic controller, PLC, or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures.PLCs are used in many machines, in many industries.PLCs are designed for multiple arrangements of digital and analog inputs and outputs, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact.ore recently, PLCs are programmed using application software on personal computers, which now represent the logic in graphic form instead of character symbols. The computer is connected to the PLC through Ethernet, RS-232, RS-485, or RS-422 cabling.
Also in the interest of how PLCs work, you may like to see the PLC History or the Smallest PLC pages on this website. Or maybe you would like to register for our self teach PLC programming course which is in the making.he CPU-Central Processing Unit. How PLCs work is down to the CPU, the CPU is the PLC part which is the brain of the whole PLC. This module typically lives in the slot beside the power supply or is incorporated with a power supply.
