Programmable Logic Controllers (PLCs) are general-purpose control devices often used in plants or manufacturing systems. They provide both a useful and efficient control solution for a variety of applications, and can accept inputs from a variety of devices, such as motion detectors, joysticks and buttons, amongst others. In turn, PLCs are able to produce outputs that control lights, motors and sound effects, amongst others. Programming resources for this input-output system can include timers, counters and other variables.
