Automation based elevator control system

Paper addresses concept of Elevator System, a controller that consists of a programmable microprocessor which is programmed using a specialized computer programming language. Programmable logic controllers deliver a flexible range of functionality and also include basic control of relay, process control, motion control and complex networking. It also serves as Distributed Control System. There are many types of interfaces which are used to interact with the programmable logic controller with the purpose of configuration or usage such as switch boards, text displays, lights or even more complex systems such as a computer Web interface as a SCADA system.
