DS215KLDBG1AZZ03A DS200KLDBG1ABC sent to the three I/O buses, the controller receives data from the three I/O buses and votes, and sends the voted data to three independent processors, each processor completes the data operation, the controller votes on the results of the arithmetic operations in the three channels and sends the results of the vote to the I/O buses, the output module receives data from the I/O bus and votes, and sends the results of the vote to the three channels to carry out the data output processing, and outputs the drive signals after voting on the processed results.

DS215KLDBG1AZZ03A DS200KLDBG1ABC sent to the three I/O buses, the controller receives data from the three I/O buses and votes, and sends the voted data to three independent processors, each processor completes the data operation, the controller votes on the results of the operation in the three channels and sends the voting results to the I/O buses, the output module receives data from the I/O buses and votes, the voting results send the three channels for data output processing, the processing results vote to output the drive signal. The output module receives data from the I/O bus and votes, and the voting results are sent to the three channels for data output processing, and the driving signal is output after the processing results are voted.

DS215KLDBG1AZZ03A DS200KLDBG1ABC Controller module and I/O module support redundancy configuration. The redundancy module adopts the dual operation mode and works at the same time without any difference between master and backup. In redundancy mode, if a module failure is detected, it will automatically block the data of the failure module and receive the data of the healthy module, and the failure module can be replaced online.

DS215KLDBG1AZZ03A DS200KLDBG1ABC Features
Full redundancy + triplex architecture design, true triplex redundancy fault-tolerant system, support 3-3-2-0 degradation mode
Ensure security while maximising availability and reducing economic losses caused by unintended stops!
■ Multiple voting mechanism (5 levels), multi-level fault-limited zone design
Isolates faults to the smallest possible extent, preventing them from spreading and improving system safety and availability indicators
