PLC an acronym which stands for programmable logic controller is the most widely used microprocessor based control system in the industry. It is a special computer specifically designed and fortified to handle control problems in the industry. It works in conjunction with sensors which serves as feedback to the process or machine and can be likened as the eyes of the PLC. The signals from the sensors are analyzed and controlling actions taking by the PLC on the process/machine according to the stored program of instruction in the memory of the PLC. The PLC ensures consistency, efficiency, economy and safety in the industrial production system and processes.
