The Programmable logic controller (PLC) has evolved as a consequential controller in the industrial automation sector because of its simplicity and ruggedness. A PLC is used to control the different mechanical motions of machines or to control the voltage or the frequency of power source. In this article, the study of the PLC has been done in great detail and also several industrial applications have been studied and realized through ladder diagrams. The applications on which we have stressed on is loading and unloading of heavy cement blocks into a chamber were autoclaved aerated concrete (ACC) cement blocks are heated for hours. Presently, the cement industries utilize the thermal ovens for heating the ACC cement blocks which require separate cart and cart path for each thermal oven thereby consuming more space, therefore the proposed design is effective to rectify this issue by implementing the cart which is unidirectional in nature. There are number of heating stations available for heating the blocks. If station 1 is full the cart will move to station 2 and there is another mechanism which is controlling the blocks to load and unload from the stations via a robotic arm, but in this project we are implementing it with only one heating station. The cart has two different mechanisms it moves in to and fro direction and forward and invert which can be controlled by relays via PLC.
