Technological revolution in Industrial Automation using PLC

Abstract

In any industry having automation work have many devices which are interconnected through wires and making all of them work together and handling their features collectively is the work of PLC (Programmable logic Controller). They are most forwardly used as they are simplest forms of control structures that are now taking over the hard-wired Relays. PLCs which are computer-based controllers are the exceptional for handling systems, which requires excessive care and accuracy like small and medium scale industries for input and Output processes. Leaning a little in the direction the utilization of Automation in Industries will only give a beneficiary performance, flexibility, accuracy, least or null engagement of human interference. And for controlling and tracking of the large scale industries where PLCs are not enough, SCADA (Supervisory Control and Data Acquisition Systems) are used as they are more efficient, and can be handled without difficulty from the main control room/office which is remotely located at other place or at far area. One of critical function of PLC is that its input and output elements can be prolonged according to the requirement or motive. They are very easy to operate for those who are having even a basic Information.
