3、y demands of market demand manufacturing respond immediately to produce small batch, many varieties and specifications, low cost and high quality products. In order to meet these requirements, the production equipment and automatic production line of control system must have high reliability and fle
4、xibility. Programmable controller is catering to this request, it appears on the microprocessor-based general industrial control device. This paper introduces fx2n series programmable controller for the control of the manipulator, including PLC and I/O assignment graph and the wiring diagram, using limit switches and PLC program, in cooperation according to its process flow driven manipulators finish work. Because with the flexibility, PLC modularization and easy to expand, and its reliability
