<P>PROBLEM TO BE SOLVED: To localize a fault point. <P>SOLUTION: An FB card detects a communication fault. Also, the FB card counts the number of messages passing through a processing portion for each processing portion provided inside the card to execute processing. When a fault is detected, the FB card compares the number of messages counted in each processing portion. In the comparison result, if there is a difference among the numbers of messages passing through each processing portion, the FB card identifies the inside of the card to be a fault point, whereas if there is no difference in the numbers of messages, the FB card identifies the outside of the card to be a fault point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
