ムやデータの追加。The device shown in this embodiment is an electronic exchange using a storage program control method. Does the exchange have an exchange connection function? This is a device that cannot tolerate system failure. Additions, changes, and expansions of functions are performed by adding and changing programs and data. Embodiment V The electronic exchange shown here employs a storage program control system with a 16-bit 1-word configuration, and the main storage device has 17 bits for parity checking of the memory.
When all programs and data have been added or changed, the parity pit t is used as a difference flag to indicate the part of the program or data that has been added or changed. Now add programs and data.

なう。If the system goes down while processing all changes, the system will automatically restart. At this time, the presence or absence of a difference flag is checked, and if the difference flag is set, roping is performed from the old file, and if there is no difference flag, roping is performed again from the new file.

みｔ開始するようＣＣＩＫ指示する。This flag is always recorded along with the operation of CC1 by the system monitoring device EVC according to the present invention. When an abnormal CCIK operation occurs, the system monitoring device E causes the CC11H to stop. If the above 7-lag F is not set, the system monitoring device E determines that the cause of the CCI malfunction is not the changed part of the program, and updates the new file [
The CCIK instructs the CCIK to start loading the program from the external storage device FDIO.

pit? I have shown the example used, but if there are multiple parts of the program where you are adding or changing program data, and different system files are provided for each part, prepare multiple difference flags and set each difference flag. It is also easy to infer that it can be started with a corresponding t system file.

保障することができる。Since it is not possible to guarantee that the system will go down while the changed part is being processed, it is necessary to add it to the program or data, or change it)! Difference flags can be set using software for parts that are expected to be related to the gold coin part. According to this method, there is no need to change the hardware, and it is considered to be an effective restart method. In the event that the system goes down due to an error in the program or data, the device will automatically be restarted using an old file that has a proven track record.
This improves system reliability and ensures stable operating sound.
