untry, the control requirements are also increasing pattern fountain, making more and more control of part of the programmable controller to achieve. In this article, the pattern fountain as the research object, Mitsubishi FX1N series PLC as controller of the fountain. The overall function of the pattern fountain control system analysis of the position and working principle of the programmable controller. Fountain hardware building blocks and the detailed design of the hardware module, and the control mode design and program preparation. Designed to improve the the fountain system control quality, and really reached the requirements of realtime control.
