Fig. 1 is a configuration block diagram showing an embodiment of the present invention, and Fig. 2 shows an example of the number of retries until communication based on the communication request is successfully performed when the communication request is expressed by a serial number. Figure 3 shows the relationship between the maximum number of retries for each unit communication count and the new allowable number of retries set in the retry command section 5 for communication requests expressed by serial numbers. It is a diagram. 1... Communication control unit, 2... Retry control unit, 3...
