Further, the automatic diagnosis is performed only for a predetermined period, and a command for judging whether or not the diagnostic data is abnormal is issued. As a result, the automatic diagnosis period can be limited, and the data can be sent to the central processing unit only when the operation of the device indicates an abnormality.

Further, the diagnostic data is sent to the central processing unit at every predetermined interval determined by the interval setting. Thereby, the operation check of the device is performed at a predetermined interval until the use of the device is completed.

Further, the automatic diagnosis is performed at every predetermined interval determined by the interval setting, and a command for judging whether or not the diagnostic data is abnormal is issued. Thereby, the operation check of the device can be performed at a predetermined interval until the use of the device is completed, and the data can be sent to the central processing unit only when the operation of the device indicates an abnormality.

Further, a prediction processing instruction having a possibility of suggesting an abnormality is executed based on past data. This makes it possible to make a prediction that the operation of the device may indicate an abnormality.

In addition, an interval shortening instruction is issued based on the result of the prediction processing when the possibility of suggesting an abnormality is near. This makes it possible to predict the possibility that the operation of the device will indicate an abnormality, shorten the interval, and perform automatic diagnosis at a shorter interval.
