<p>PROBLEM TO BE SOLVED: To provide a signal processor that instantly changes a failed signal input-output device for a spare signal input-output device in a plurality of signal input-output devices of redundant configuration performing real time processing.SOLUTION: A plurality of signal input-output devices 9 and 10 are provided. When a failure detection signal is received from any one of the signal input-output devices, a signal processed by the input-output device having no output of the failure detection signal is output to an external device 11 via a signal converter 8. When the failure detection signal is received from all the signal input-output devices, a signal output from a signal output device 7 and input via the signal converter is adapted to be output to the external device via the signal converter again.</p> |
