PLC Based Automation for Industrial Operation

Abstract

Automation or numerical control is the use of control system such as computers to control industrial machinery and processes, replacing human operators. In the scope of industrialization, it is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. Processes and systems can also be automated. Automation plays an increasingly important role in the global economy and in daily experience. Engineers strive to combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities. Specialized hardened computers, referred to as programmable logic controller (PLCs), and are frequently used to synchronize the flow of inputs from (physical) sensor and events with the flow of outputs to actuators and events. This leads to precisely controlled actions that permit a tight control of almost any industrial process. This study in plastic industry, where the PLC an automated industry sequential operations.
