In this paper, we will work on Programmable logic Controllers to control the operation of an Industrial Crane and many other Applications which is used in the industry. Earlier in Industry, we used certain control devices which were controlled and wired directly with the system that leads to certain irregularity in the functioning of the whole system. To overcome the in-functionality of the system which was caused by large number of wires, We came cross towards Programmable logic controllers (PLC). Earlier Human controls the crane & that passes through large drawbacks such as more wiring work, appears large mechanical faults & difficulties in troubleshooting & repair work. Due to these Drawbacks the production suffers a lot and hence growth decreases rapidly.
