The Elevators/Lifts are used in multistorey buildings as a means of transport between various floors. Normally the lifts are controlled by Microprocessor based systems, which are costlier. It is proposed to design a low cost and compact dedicated controller using PAL/FPGA. The Elevator Controller is a device used to control a lift motion and to indicate the direction of motion, and the present floor level, etc. The device control the lift motion by means of accepting the floor level as input and generate control signals (for control the lift motion) as output.
