Abstract

PURPOSE: To diagnose input-output unit and an input-output controller by artificially generating an interface signal between the input-output controller and a host unit.
CONSTITUTION: Input-output units 4, 4' and 4" used normally in on-line mode are connected to input-output controller 2, which is connected to host unit 1. In case that one of units under input-output controller 2 becomes abnormal, input-output controller 2 disconnects it from hose unit 1 and then connects it to maintenance console panel 3. Through this maintenance console panel 3, an interface signal between host unit 1 and input-output controller 2 is artificially generated to diagnose the units under input-output controller 2.
