In the conventional response signal distribution method, as shown in FIG. 2, control of the devices 4 and 5 having different response signal values is performed by:
The control unit 3 requests the devices 4 and 5 and the response signals from the devices 4 and 5 are transmitted by the response signal distribution unit 6 to the response signal wait designation unit 7 and the response signal analysis unit 8 of the device 4 and the response signal analysis unit 8 of the device 4. The control is passed to the response signal analysis unit 9 and the response signal wait designation release unit 10 for processing. Thus, in the response signal distribution unit,
The apparatus is controlled by using only the response signal and always executing the response signal wait designation unit, the response signal analysis unit, and the response signal wait designation release unit.

[0004]

In the conventional response signal distribution method, only the response signal is used as a judgment material at the time of response signal distribution. is there.

In FIG. 7, a connection flag state determination 16 is performed, and if a plurality of devices having different response signals are determined to be a plurality of connections 17, in the case of a plurality of connections, a wait designation storage area setting value is calculated from the response signal storage area and the connection flag 18 And the processing 19 of the response signal waiting designating section 7, and then the processing 2 of the response signal analyzing section.
If 0 and the process 22 of the response signal wait designation canceling unit are performed, and if there is not a plurality of connections, the process 20 of the response signal analyzing units 8 and 9 is performed and the control of the device is ended.

Next, in the system according to the present invention capable of controlling the response signal value from 0 to 7, first, the device 5 in which the response signal value is 1 is connected, An embodiment of the present invention will be described.

When the present system is started, a connection flag 2 is set by the connection flag setting unit 1. The connection flag setting unit 1 determines the response signal value 14 for the device,
It is determined that the response signal value of the device 5 is 1, and the state of the signal value 1 area of the connection flag 12 is changed from 0 to 1 by the connection flag setting 15 for the response signal value. By the processing of the connection flag setting unit 1, the operation preparation of the present system is completed.

Next, when the control unit 3 instructs the device 5,
The response signal distribution unit 6 is activated by the response signal from the device 5. In the response signal distribution unit 6, the connection flag state determination 16
