制御装置に取り込む手順の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a polling device, and particularly to an improvement in a procedure for inputting input data generated by a plurality of input devices into a control device when the control device is activated.

〔発明の背景〕[Background of the invention]

ータをブロツク伝送する。 Conventionally, as a procedure for input data generated by a plurality of input devices into a single control device upon activation of the control device, a transmission control section performs boring at a constant cycle in a predetermined order for each input device. In response to polling, each input device responds with no data or, if input data is present, transmits the input data as a block.

路が高価なものとなる。 Since the control device stops polling while this block transmission is being performed, the input data generated by the other plural input devices during this time is taken into the control device in the order in which the polling is issued. Therefore, even if input data is generated on the input device in the opposite order to the polling issuance order, the input data generation order seen from the control device will be the polling issuance order, making it impossible to reproduce the actual input data generation order. . As a countermeasure to this problem, the transmission speed may be increased so that the data transmission is completed within the polling cycle, but the transmission circuit becomes expensive.

渡す。 FIG. 2 shows the procedure of the present invention in a time chart format. The transmission control unit 2 issues polling 6 at predetermined intervals and in a predetermined order. The input devices 4 of a to e return responses 7 to the polling. If the input data permutation 8 generated at the input device occurs as shown in the figure, the C input device will:
Returns the first character of the input data. The transmission control unit 2 receives this, and the control unit 2 also confirms that the data of the C input device is number 1 in the permutation.
Let me know. In the next polling cycle, the C input device returns the second character of the input data. The e-input device returns the first character of the input data. The transmission control section 2 receives these and notifies the control device 1 that the data of the e input device is the second in the permutation. Thereafter, the above-described procedure is repeated, and when the transmission control unit 2 receives a character indicating the end of data as a response from the input device, the data from the input device 4 is passed to the assembly control device 1.
