態とする。Now, a communication 1w1I@device IK failure has occurred, and the backup switching device 6 switches the communication control device 1 and the backup communication control device 5 manually or by instructions from the processing device 1 (not shown).
%: If switched, switched? llJ@■7 switches the connection to the line from the communication control device 1 to the communication control device 5 using the changeover switch section 8, and also sends a switching signal 19k S V P
Send s2Vc. Upon receiving the switching signal 19, the 5VPI 2 determines that the communication control device 1 has been switched, and selects and reads the address and control information of the communication control device 1 from the FD unit 14. The 5VPI 2 initializes the communication control device 10 by writing this address and control information into the device address memory 15 and each line op-scene memory 17&C, and then puts the communication control device 10 into an operating state.

動作する。Furthermore, at the same time as the switching, the switching signal 20 is transmitted to the communication 8m device 1.
The communication control device 1 becomes inactive. In this way, from now on, the communication control device 10 using the address and control information of the overconfident Liu Goso arrangement operates in place of the communication control device 1.

は４０代わりとして動作する。Similarly, when the communication control device 2.5 or 4 is switched, the 5VP 12 switches the communication control device 2.5 or 4 based on the content of the switching signal from the switching 11j@ section 7.
The communication control device 10 operates in place of the communication control device 2.3 or 40 because the address and control information of the communication device IO are read from the FO unit 14 to initialize the communication device IO.

でなければならないとい５ Ｉｆ隈はない。Effects of the Invention As mentioned above, the communication control device implementing the present invention has the following advantages:
When used as a standby device, it is possible to set not only the addresses necessary to operate as a switched working device when one switch occurs, but also control information corresponding to each line. In addition, the 70 Liu control information is stored separately in the FDK recorder with the contents corresponding to each active aircraft, so the configuration of each active aircraft and standby aircraft can be controlled with the same control information. There are no 5 Ifs.
