4. Working Principle
After power-on, the Motorola MVME6100-0173 single board computer initiates a hardware self-test routine that verifies the processor, ECC memory, NVRAM, bus interfaces, network and serial ports, RTC and watchdog module comprehensively. Once the self-test passes without errors, the system controller and VME bus are initialized, the embedded operating system and user-defined control program are loaded, and the board enters normal master control operation.
During runtime, the MPC7457 main processor paired with the AltiVec coprocessor executes core tasks including system logic computation, data parsing and control instruction scheduling. Real-time error correction via ECC memory guarantees the accuracy and integrity of computational data.
Data interaction is established with all I/O boards and functional modules within the rack over the VME bus to collect field operating data and issue equipment control commands. Remote system networking, data uploading and parameter interaction are realized through the dual Gigabit Ethernet ports, while industrial serial ports handle communication with lower-level devices and on-site maintenance debugging.
The onboard hardware watchdog and fault self-diagnosis modules monitor system status continuously. In the event of program exceptions, bus faults, data errors or communication outages, an automatic reset or fault alarm is triggered, the fault state is locked and event logs are recorded. The NVRAM module stores key system parameters and operational data in real time to prevent data loss upon power failure.Task scheduling for PMC daughtercard expansion functions is also supported to flexibly accommodate diverse control requirements, ensuring stable, precise and continuous operation of the embedded control system throughout the entire lifecycle.
