Abstract

PURPOSE: To simplify a control program by causing a monitor SVP to control directly a processing unit by using a control bus and a data bus in the system bus connection system between the system controller and each processing unit.
CONSTITUTION: Processing unit 30 is connected from service unit 300 to CPU adapter 220 of operation board 20 through CPU connection bus 50 and connection/ disconnection control function switch S2, and is further connected to SVP adapter 110 in the system controller through SVP connection bus 40, and is controlled by control SVP 200 of operation board 20 or monitor SMP 100 in the system controller. Control SVP 200 is connected to SVP connection bus 40 through SVP adapter 210 and switch S1 which interlocks with switch S2.
