IV. Working Principle
The VM600 IOCN series module is the core communication and logic control hub of the VM600 monitoring and protection system, embedded installed in the rack main control slot, and cooperates with the CPUM main control card to complete full machine system scheduling, data interaction, network communication and logic interlock functions. After power-on, the module automatically completes hardware self-inspection, bus initialization, protocol loading, redundant pairing and I/O port initialization. After self-inspection is correct, it enters the normalized main control operation state, and real-timely takes over the system management and data forwarding work of the entire rack.
During normal system operation, equipment status data collected by vibration acquisition modules and signal conditioning modules in the rack is summarized to the IOCN module through the backplane high-speed bus. The module performs time sequence calibration, unified sorting, operation filtering and threshold comparison on all scattered data to generate standard monitoring data, status trends and fault alarm information. On the one hand, it uploads to upper monitoring software, DCS and PLC systems through multi-protocol communication ports to realize remote monitoring, data storage and trend traceability; on the other hand, it outputs alarm and interlock instructions through isolated I/O loops to link on-site protection equipment and complete unit safety protection.
Under redundant architecture operation, dual IOCN modules perform real-time heartbeat interaction, data mirror synchronization and mutual inspection of working status. The master module is fully responsible for system scheduling and data output, and the standby module synchronizes data uninterruptedly in standby state. Once the master module has hardware failure, communication interruption or bus abnormality, the system seamlessly switches to the standby module immediately, without data loss, logic interruption or working condition disturbance throughout the process. Meanwhile, the built-in self-diagnosis system of the module real-timely monitors the status of bus, communication ports, I/O loops and power supply, accurately identifies various abnormalities and latches alarms, realizing rapid fault location and single-point isolation, and continuously ensuring stable and controllable operation of the entire system.
