With thePLC inChina's rapid development, the fountain ofartistic controlrequirements are also getting higher and higher, making more andmore control ofthe PLC needs toachieve. Heplace usually patronized atthe visitor and the residents, like park, square, travel beauty spot and some well-known buildings before, usually build some fountains toprovide people recreation, fountains spray water style according tothe certain regulation change, ifmatch each other with colourful light again tomatch, make person free ofmind and happy ofheart more inwith harmony the grace ofmusic, linger on, forgetting this text relate ishow make use ofaPLC control fountain tospray water method, produce the style ofeach kind. Based onthe mission design requirements tofourCentral fancy fountain for the study using aseries ofCPM2A PLC asa fountain ofthe controller. The fancy fountain ofthe overallcontrol system features an analysis ofthe PLC positionand working principles. And made afountain ponentsand modules detailed design ofthe hardware module. The design ofthe fountain system toimprove quality control, and really reacheda real-time control requirements. Key word :PLC (programable logic control )Fanc
