Abstract: Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications with minimal or reduced human intervention. In order to control various plant process and industrial operations, scientists have introduced computer based controllers like PLC, DCS etc. Pneumatic conveying of AlCl3 and blow pot automation is carried out using Programmable Logic Controllers (PLC).The predecessor for the PLC system is Relay System which has many disadvantages And to overcome that disadvantages, we have introduced Computer based automation it in our paper.
