<p>PURPOSE:To raise transmission rate and to make communication distance long by executing the control of a tri-state driver with a serial transfer data. CONSTITUTION:The transfer data from the interface 41 of a robot controller flows in the order of an electrooptical conversion circuit 22 an optical cable 23 a photoelectric conversion circuit 25 a tri-state bus driver 26 a bus line A 68, and is received by a cell controller 10. The data transmitted from the cell controller 10 flows in the order of a bus line B 69 a receiver 28 the electrooptical conversion circuit 22 the optical cable 23 the photoelectric conversion circuit 25 the robot controller interface 41, and is received by the robot controller. The optical cable is used between the interface 41 of an FA equipment and a terminal 64, the control of the tri-state bus driver is executed by the transfer data, and the communication path is made short.</p> |
