Abstract
This design introduced the gunction and merits of the FX2N PLC. Programmable controller short for PLC,Because PLC has outstanding function, also has perfect function competenee, plus flexibility better current use of computer’s Form electronic control equipment which core on microcomputer PLC control technology. Programmable controller is aspcial digital running electrican system which design for industry circumstances. Because PLC has so many merits , now industry product mostly adopt PLC to bring about .
This control system , based on the request of practice adopt the PLC’s merits to finish the control of system. at the present This thesis has the system’s scheme of hardware main circuit diagram and software design.
Keywords: Programmable controller, memory, computer technology,communication
