Abstract
PURPOSE:To eliminate a trouble display device, a cable driver, etc., by using a common bus and an interface circuit to read trouble indications of a slave processor from a master processor. CONSTITUTION:Fixed master processor 1 and slave processors 3 and 4 are connected through a common bus 2, and slave processors 3 and 4 consist of interface circuits 5 and 6, CPUs 7 and 8, and trouble indication registers 9 and 10. The trouble information read command received from the master processor 1 through the common bus 2 is decoded by interface circuits 5 and 6, and much urgent information in trouble indication registers 9 and 10 and information of the change request of the system are edited and are returned to the master processor 1 through the common bus 2. Thus, a trouble display device, a cable driver, and a relay are eliminated.
