Abstract

PURPOSE:To easily separate a fault by an additive bus adapter and to improve maintainability. CONSTITUTION:This device is equipped with the two systems of additive bus adapters for connecting a basic input/output bus 1 and an additive input/output bus 2. One is an operating system additive bus adapter 21 used for the normal exchange of information, and the other is a monitoring system additive bus adapter 22 for monitor. When exchanging information between an input/output device 6 and a main storage device 4 by the operating system additive bus adapter 21, the information to be received by the operating system additive bus adapter 21 is stored by a storing means 31 in the monitoring system additive bus adapter 22. The information transmitted by the operating system additive bus adapter 21 is compared with the information stored in the storing means 31 by a comparing means 32 in the monitoring system additive bus adapter 22. When the compared result shows difference, error signals are outputted to an operation processor 3.
