A Programmable Logic Controller (PLC) is a special digital computer device which used for industrial Control systems.Its used for adepted for the control of manufacturing processes,robotic devices or any activity that requires high reliability control.PLCused in many industries such as oil refineries,manufacturing lines,conveyer systems.A computer processor that is called CPU that is described to run one program and has a monitors a series of different inputs and logically mainpulates the outputs for the desired control.Have no mechanical failour that is advantage of PLC.PLC Output can include element such as indicator lamps,sirens,electric motors,hydrolic and so on.They are one of the most advantage and simplest forms of control systems which are now replacing hard wired logic relays at a large scale.Siemens TIA portal is very easy to learn and its you can convert ladder logic into any PLC language.
