ABSTRACT With the continuous development of society , with the needs of human life , the application of the PLC has penetrated into all areas of the national economy, peoples production and life has played a huge role can not be replaced , while driving the rapid updating of traditional control testing . Understand and apply knowledge PLC is a strong and profound usability thing this system is the use of programmable logic controller (PLC), PLC- based controller, to achieve full control of fancy fountain . Systems with a high degree of automation stable operation, high precision, easy to control, is widely used in various places of life. This article discusses the fancy fountain control systems, completed a fancy fountain system, all the basic work . On the use of personnel is also limited to a simple button operation, basically automated control . This topic describes the use of the production of Mitsubishi FX2N-32MR series of programmable controllers , use ladder programming , while the overall function of the spray pond fancy control system is analyzed , elaborated composition and working principle of the programmable controller . This design improves the quality fountain control systems , and achieve real-time control. In order to satisfy the diversified
