<p>PURPOSE:To provide the controller for a device in which the load of a device being a main station at transmission reception is relieved, accuracy of a device being a slave station for a longer time of 1sec or over is warranted and a reference time is used in common. CONSTITUTION:The system using the controller is provided with a device 15 being a master station and a device 16 being a slave station, and the device 15 is provided with a synchronizing signal generating means 19, a transmission means 20, a reception means 21, a control means 22, a counting means 23 receiving a reference signal from the control means 22 and counting a time in the device being the master station. Furthermore, the device 16 is provided with a reception means 24 receiving a data transmission text sent from the device being the master station, a transmission means 25, a control means 26, and a counting means 27 receiving the reference signal from the control means and counting a time of the device being the slave station. Then the device 15 keeps sending the data transmission text to generate the reference signal by the device 16 at all times.</p> |
