Combining two redundant 9907-838  into an organic whole typically includes multiple technical points such as:
1) Information synchronization technology
It is a prerequisite for achieving bumpless switching technology between working and standby components. Only by implementing high-speed and effective information synchronization according to the real-time control requirements, and ensuring that working and standby components work in sync, can bumpless switching between redundant components be achieved.
In the hot standby working mode, one of the modules is in the working state (work card), achieving functions such as data acquisition, calculation, control output, and network communication of the system; And the other one is in standby mode (standby card), which tracks the internal control status of the work card in real-time (i.e. state synchronization). The positive/negative logic between work/backup 9907-838  is mutually exclusive, meaning that one is a work card and the other must be a backup card; Moreover, there are redundant control circuits (also known as working/standby control circuits) and information communication circuits between them to coordinate the simultaneous and orderly operation of two cards, ensuring the consistency of external input and output characteristics. For user use, it can be considered that there is only one component. In general, in design, high-speed redundant communication channels (serial or parallel) are used to achieve mutual inspection of operating status and synchronization of control status (such as configuration information, output valve position, control parameters, etc.) between working and standby components.

2) 9907-838  Fault detection technology
In order to ensure that the redundant parts of the system are put into operation in a timely manner when faults occur, high-precision online fault detection technology must be available to achieve fault detection, fault location, fault isolation, and fault alarm. Fault detection includes power supply, microprocessor, data communication link, data bus, and I/O status. Among them, fault diagnosis includes fault self diagnosis and fault mutual inspection (mutual inspection between working and spare cards)
