ABSTRACT: An integrate method of controlling the copper Continuous Extrusion production line which use Computer is introduced . This system can provide the user with the dynamic display of production line’s and the Programmable Logic Controller ( PLC )’s state messages or the output of the report forms, which uses Graphic Operation Terminal as the upper computer and uses the software as the users’ customization operation flat in which the line’s real time control and the state display is performed . As the reliability and stability of the PLC, it is connected to computer with RS-422 and is used to acquire data, execute the upper computer’s commands, perform the logic control and the real time control. Continuous Extrusion production line’s automatic supervisory control system ,with modern electron technology and computer ,is developed .It’s performance is reliable and it’s operating is easily and it’s work is not fault with continue long time . Keyword : copper Continuous Extrusion PLC supervisory Fuzzy control
