Abstract
PURPOSE: To know the operation state of an I/0 controller by performing a select sequence by permitting the I/O controller to inform a channel of it operation state by making use of the period when the I/O controller is not coupled with the channel.
CONSTITUTION: Bus line 3 connected to the channel and operational in line 4 are connected to more than one I/O controller to constitute an input-output system. Cable driver 5 and cable receiver 6 of this controller are connected to in line 4, and bus in bits 0W7 of bus line 3 to bus drivers 7-0W7-7 respectively. Further, AND circuits 9-0W9-7 receiving operational in information on their system and AND circuits 10-0W10-7 with NOT input are connected to drivers 7-0W7-7. If all I/O controller including those of this system are not coupled with the channel, the output of receiver 6 is held at zero and the output of address recorder 11 is supplied to drivers 7-0W7-7 by way of circuits 10-0W10-7, so that the operation state can be reported to the channel.
