Many industrial and control applications are running through conventional PLC technology adequately because PLC provides flexibility, lower cost and security compared to other control techniques, but still a more powerful alternative is needed. In recent years, FPGA's becomes the best replacement of PLC to implement control algorithms in industrial, digital signal processing, video and audio applications and as well to perform control tasks. The basic dilemma of FPGA's is that it requires an expertise in control automation applications. In this paper, an efficient methodology is proposed to implement PLC state diagram on FPGA using Xilinx StateCAD tool. Three level efficient elevator control system is designed which can be used for different elevator control system having different number of floors.

Abstract
Many industrial and control applications are running through conventional PLC technology adequately because PLC provides flexibility, lower cost and security compared to other control techniques, but still a more powerful alternative is needed. In recent years, FPGA's becomes the best replacement of PLC to implement control algorithms in industrial, digital signal processing, video and audio applications and as well to perform control tasks. The basic dilemma of FPGA's is that it requires an expertise in control automation applications. In this paper, an efficient methodology is proposed to implement PLC state diagram on FPGA using Xilinx StateCAD tool. Three level efficient elevator control system is designed which can be used for different elevator control system having different number of floors. Simply changing the state diagram, VERILOG HDL(Hardware Description Language) code is generated and used in XILINX ISE 7.1i to implement control system on FPGA Spartan-3. StateBench simulator is used to simulate results of proposed control system.
Author Keywords: Programmable Logic Controller, Field Programmable Gate Array, State Diagram, StateCAD, Hardware Description Language.
