We were supposed to do programming of PLC with language called Ladder Diagram. Luckily the project was group project so I had friends to help me but then worst part of the project was that the project carried only 5 %. Whole the week i was working hard to get this thing done. There were many things to be understood like how to do programming, how to use motor and relay and then how to make switch connections with the PLC panel. Well step by step and slowly and gradually we managed to get all of them. The Elevator we desgined and constructed had three levels on it, the user can press switch to call the elevator at any floor and then go to any particular floor. No doubt every thing seems easy until u do it urself. Once u start doing it, u feel how hard it is. ...
