Title:
MULTIPLEX CONTROL APPARATUS AND MULTIPLEX CONTROL METHOD
Document Type and Number:
Japanese Patent JP2014211784
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multiplex control apparatus capable of suppressing the reduction in reliability.SOLUTION: The multiplex control apparatus registers an error event as a log into a system log. The multiplex control apparatus obtains the number of error occurrences in a predetermined time period from the system log, and, when the number of errors arrives at a predetermined number, estimates that a permanent error occurs. The multiplex control apparatus expresses the estimated permanent error. Thus, even when various components having insufficient error related information are mounted, a permanent error can be estimated, and the reduction in reliability of the multiplex control apparatus can be suppressed.
