握することを特徴とする予備系の正常性確認方式。One system exists, with a redundant control processor that controls the system, and a system with multiple redundant processing processors that perform data exchange processing. In a dual-configured distributed processing data exchange that connects two communication buses, the active side (hereinafter referred to as ACT) of the control processor has a means to be connected to both communication buses, and the standby side (hereinafter referred to as SBY).
has means to be completely separated from the communication bus and means to send and receive command activation and response information between the control processors ACT and SBY, and the control processor of the ACT is connected to the ACT.
In addition to performing data exchange processing using the communication bus and processing processor of SBY, periodically issuing a normality confirmation command to the processing processor of SBY via the communication bus of SBY, and receiving the response, the processing processor of SBY The status of SBY is constantly monitored, and SBY's processor is
Since T's control processor monitors the status of SBY's processing processor, there is no need to do anything, and the built-in detailed diagnostic program is run according to instructions from ACT's control processor to check the health of the hardware. A standby system normality confirmation method characterized in that the status of not only the ACT system but also the SBY system can be reliably grasped by constantly returning responses to the ACT control processor.
