In today’s competitive world, for an industry to flourish it is very important that the overall efficiency of an industry should be high, for this to accomplish, the various control systems in process control should operate with high efficiency, speed and accuracy. So in such scenario, the system with which are operated in conventional methods like hard-wired relays have numerous drawbacks and limitations. To overcome the drawbacks that occur in relays, it is replaced by programmable logic controllers (PLC).A PLC is designed to perform the control operations logically by making the use of a program fed by the user. Due to this we can give various inputs to the PLC where the inputs can be changed according to the ladder logical program made by the user. The main aim of our project is to control the Bucket wheel Excavator in mining area. To control Boom1- Hoisting & Lowering, Total Structure - Slew Left & Right, Machine Movement - Forward & Reverse, Belt 1 & 2 - Start & Stop using With PLC.
