摘要：PURPOSE:To obtain a high operating rate by coupling a diagnostic MPU with anexecution MPU roughly through a communication line, collecting and analyzing data of ashutting-down MPU, and restarting the diagnostic MPU. CONSTITUTION:By a tag signalof an error, a diagnostic MPU18 collects data on a bus and stops the operation of anexecution MPU10, and up-to-date error information and the operation of the MPU10 areanalyzed to judge whether reporting to an operator or restarting is to be done. When itis decided that the restarting should be done, the MPU18 generates a reset signal forthe execution MPU in a diagnostic I/O port 23 and restarts the MPU10 through adiagnostic I/O line 28. Then, the MPU10 diagnoses itself and also has a communicationwith the MPU18 to fetch data right before the occurrence of a system fault. Then, thesystem is started at the head of a minimum block which allows successive systemprocessing.
