VALVE DRIVING CONTROL DEVICE

PURPOSE:To simplify configuration in the manner of a hardware and to improve efficiency for debugging, development and improvement in the manner of a software by specifying a desired valve among plural valves and controlling the ON/OFF of the desired valve according to the data value of one data line. CONSTITUTION:Only one data line 13a is used for one address shown by plural address lines 12 and in order to distinguish plural valves, only one address is certified by making one address coincident to the one valve. Therefore, all the valves can be connected in common by only one data line 13a. In a driving control signal generation circuit 14, it is not necessary by holding the data of the data line 13a to execute holding and reloading operations in the software, and the same data can be overwritten as well at the same address without any problem. Thus, since the circuit configuration can be simplified in the manner of the hardware and program preparation can be easily executed in the manner of the software, efficiency can be improved for debugging, development and improvement.
