PLC (Programmable Logic Controller) programming allows a computer to automate mechanical or electrical processes for machinery, lighting, or assembly line control actions. Over the past two decades, PLC programming has been used in a number of industries. The PLC’s design allows it to take multiple inputs and provide various outputs. A PLC device is also referred to as a hard, real-time control system since its output(s) is in direct response to input conditions within a pre-arranged time frame.
