It was designed to do so. In addition, when a specific station is initialized during operation, the stored information is used to execute a program that performs processing such as activation of the line connected to the station. .

１１からその情報を受ける。Next, the operation of the above embodiment will be explained. In the above embodiment, when the master station 11 operates, it notifies each slave station 12 of fixed connection information line-specific information that is centrally managed by the master station,
Each slave station 12 retains its information in nonvolatile memory 15. If a station where all stations are in operation is initialized due to the occurrence of a failure, etc., the line connected to the station is activated based on the setting information held in the nonvolatile memory 15. etc. Additionally, information abnormalities are detected by constantly checking the contents of the non-volatile memory 15, and in the case of memory with battery backup, abnormalities are detected by battery voltage inspection.
If necessary, the information is received from the master station 11 by issuing a resetting request to the master station 11.

ともなう情報の伝送を最小限にすることができる。As described above, the above-mentioned embodiment has the advantage that when an arbitrary station is initialized due to a failure or the like, the dedicated line recovery process can be performed using the information held by the station, and the recovery time can be shortened. In addition, if there is a possibility that the setting information of the non-volatile memory 5 page memory 15 has been destroyed, the settings will be reset from the master station 1, so the transmission of information associated with the initialization of the station will be minimized. be able to.
