CONSTITUTION:In an on-line network for executing a data processing by means of an on-line real time, to remote CPUs 21-2n is connected a microcomputer which starts when its function has stopped, and by this microcomputer, an alarm information consisting of kind of a fault in the remote CPUs 21-2n, cause, generation time, an instruction matter to a center operator, etc. is generated, is sent to the central CPU1, and a fault state is reported to a center operator.
