Abstract

PURPOSE:To distinguish a continuous error from an intermittent error by taking it as an intermitter error if b-set or over abnormal data exist intermittently in m-set of received unit data and taking it as a continuous error if a-set or over of abnormal data exist continuously. CONSTITUTION:A RAM 8 is provided with a reception counter 10, an intermittent error counter 11 counting an intermittent error and a continuous error counter 12 counting a continuous error, and a ROM 7 has a program processing data for each data and a processor 5 operates each counter according it to inform an intermittent error and a continuous error. An abnormalness detection function 9 of an interface 6 analyzes a received data and if any abnormalness exists, 1 is incremented to an intermittent error counter 11 and a continuous error counter 12 and if no abnormal data exists, the continuous error counter 11 is made zero. Thus, it is taken as an intermittent error if b-set or over of error data exist in m-set of data and it is taken as a continuous error if a-set or over of error data exist continuously.
