Abstract

PURPOSE: To prevemt the monitor display from being overlooked to prevent an erroneous switching dependent upon misunderstanding of the monitor display by giving the interlock relation between a switching instructing function and a monitor display function and giving a constitution where the switching instructing operation is performed through the monitor display instructing operation.
CONSTITUTION: In the unit where switching information of switching information designation part 1 is stored in switching information memory part 10 through switching information receiving part 6 and information is read out from memory part 10 at the time when a switching instruction is issued from switching instructing receiving part 8 and this read information is sent to a channel switch which is interposed between CPU and I/O devices, the instruction of monitor display instructing part 2 is supplied to switching control part 9 and memory part 10 through monitor display receiving part 7. Then, at the time when the display instruction is issued from receiving part 7, the connection state signal from the channel switch and the switching information of memory part 10 are compared with each other in display control part 11; and if switching information is proper after the monitor display instruction is accepted, information is displayed on monitor display part 4 and the switching instruction is accepted.
