<p>A method of driving and controlling a solenoid-operated valve is provided. The solenoid-operated valve can be centrally controlled and managed and it is possible to easily respond to any system change. The solenoid-operated valve is provided with a solenoid-operated valve driving control circuit for receiving solenoid-operated valve opening/closing control data from a serial bus as serial data including two bits for each of two solenoid-operated valve coils of the solenoid-operated valve; converting the data into parallel data; driving the solenoid-operated valve coils based on one bit of the two bits for each solenoid-operated valve coil in parallel data; driving light emitting diodes based on the other bit; and inputting an output from a sensor for detecting each of open and closed states of the solenoid-operated valve and a signal indicating whether each of the solenoid-operated valve coils has a single-coil structure or a double-coil structure by a switch; and converting the input data for sending to the serial bus.</p> |
