PROBLEM TO BE SOLVED: To allow a suspicious control unit in which abnormality has occurred, to be maintained while continuing operation, even when the suspicious control unit is erroneously specified.SOLUTION: Each of CMs 11A and 11B includes an interface unit 14, a first detection unit 12a, and a reset control unit 12b. The interface unit 14 is connected to a communication channel 40 to control communication on the communication channel 40. The first detection unit 12a detects abnormality on the interface unit 14 of the own CM 11A, the interface unit 14 of the other CM 11B, and an inter-CM path P1 including the communication channel 40. If the first detection unit 12a detects abnormality on the side of the other CM 11B, the reset control unit 12b degenerates the other CM 11B and resets the interface unit 12 of the own CM 11A. |
