Abstract :
The authors describe an optical fiber control signal transmission system in which multiples frequency signals are used as an 8b control signal for a CPU control system consisting of Z80 data processors, motion control devices, and position sensors. Four control terminals are connected to the control center. Motion control devices are connected to the data processor installed in each control terminal. Frequencies at 100 kHz, 200 kHz, 300 kHz, and 400 kHz are used as series signals to specify the current operating states of the motion control devices, and the frequencies at 500 kHz, 600 kHz, 700 kHz, and 800 kHz are used as parallel signals to specify the four control terminals. The initial step in implementing the transmission system, including the function of the control bus and the configuration of the transmission system for the 8b parallel control signals, is discussed
