Abstract

PURPOSE:To reduce a load on each station by regarding one of function modules as a diagnostic station and by diagnosing each station by the diagnostic station. CONSTITUTION:Diagnostic station 18 sends a diagnostic frame to control station 14 to make a diagnosis. Control station 14, on the other hand, sends a diagnosis result back with an answer frame. Next, diagnostic station 18 checks the answer result to judge a fault. As a result, if specific control station 18 is judged to be abnormal, the discrimination is carried out by combining the said result with diagnosis results of the following stations.
