Abstract

PURPOSE: To make it possible to generate easily a fault or a specific state artificially by arranging a pseudo fault generator between a higher unit and lower unit.
CONSTITUTION: In pseudo fault generator 4, generation-condition detection part 44 supervises the IF response operation of lower unit 2 to higher unit 1 via both interface IF parts 41 and 42 and IF control part 43 all the time. Next, when the generation condition set 47 and stored 47 is detected 44, it intervenes in the IF response operation and pseudo-state generating part 45 suppresses an IF signal from unit 1 to unit 2 or in the opposite direction at adequate timing determined by kind-report timing of a fault or specific state set 46, and also performs the IF response operation to unit 1 as a substitute for unit 2 so as to read report information, etc., of memory part 47, thereby making a report via control part 43 and IF part 41.
