Uses the PLC control pattern eruptive fountain, has the easy to operate, the movement is reliable, control segment design simple and so on merits. With the SFC method programming, may cause the design mentality to be clear, the programming is convenient. If needs to change the spraying of water pattern and the spraying of water time, the design proposal does not need to make the very big adjustment, so long as makes the control procedure the corresponding revision, then realizes the control goal. key word: PLC floral formula eruptive fountain control system
