た。Furthermore, since there is no interlock between the individual switching devices, input/output devices may be connected to the input/output device corresponding portions of the same standby control device at the same time. In the method of switching in block units shown in FIG. 2, even if there is an input/output device that can be used for testing, switching can only be done in block units, so an input/output device exclusively for testing is required, which is uneconomical.

An is A1 of the input/output device corresponding section 4 of the control device 3 of the current A
~An to A1 to N of the input/output corresponding section 4 of the preliminary control device 3
1...Switches to An-Nn all at once. In addition, when an arbitrary input/output device 1 is used for testing during a test, for example, when DAl of the input/output device 1 is used for testing, the individual switching circuit is activated by an individual switching signal issued from A1 of the individual switching control section 12. DAl of the input/output device connected to A1 of the input/output device corresponding section 4 of the control device 3 of the active A is switched to A1 to N1 of the input/output device corresponding section 4 of the standby control device 3. . Due to the interrotter control signal issued at the same time as the individual switching control signal, the plurality of input/output devices 1 will not be connected to the input/output device corresponding section 4 of the preliminary control device 3 at the same time. With the configuration as described above, the following effects can be obtained in the present invention.
