Abstract

PURPOSE: To shorten the logout processing time to the utmost in case of the anomaly processing of a channel device by using a diagnostic unit to perform the anomaly processing of the channel.
CONSTITUTION: Diagnostic unit 2 is provided in CPU 1: and when anomaly is detected in a channel to which CPU 1 instructs operation, a cause channel logout instruction is issued to interrupt the processing, and simultaneously, a diagnostic interrupt is caused to unit 2. Then, unit 2 acquires logout information in abnormal channels 3-1 to 3-n by diagnosing link 5 and transfers it to CPU 1, and simultaneously, unit 2 clears the operation state of these channels to report the end of the processing to the CPU. Then, the CPU starts the processing again on a basis of this report.
