PURPOSE:To simplify a constitution by using a special frame in an information processing system where a clock master station, nodes and an information processor are connected in loop and the said information processor is used in common from the nodes. CONSTITUTION:The figure shows a frame format used for this information processing system. A start code 106 is transmitted periodically from the clock master clock. Communication information 100 is divided corresponding to the input/ output channel number of the information processor. Control information 104 is assigned fixedly to each node. A calling code is transmitted to one's own time slot location of the control information 104 in the calling from a node. The master station transmits the information number corresponding to an idle input/ output channel in the same time slot. The calling node communicates with the information processor by utilizing the information channel. |
