Core Functional Features
Real-time Redundant Control: Combined with PMC optical reflection memory card, realizes nanosecond-level data synchronization among multiple CPU control nodes, up to 256 control nodes in a single fiber ring network, ensuring complete consistency of key protection data such as gas turbine tripping， speed， and temperature
VME Bus Master Control Capability： Can uniformly schedule I/O modules of the entire rack， perform timing arbitration， and protect against hardware watchdog to prevent system from crashing， compatible with GE’s old Mark V/Mark VI steam turbine control systems
Wide Temperature and High Reliability Reinforcement Design： Compatible with power plant cabinets， vehicles， and airborne environments with harsh electromagnetic and temperature variations， supports long-term 7×24 uninterrupted operation
Rich Expansion Compatibility： Can be expanded with motion control， high-speed acquisition， Profibus， and other types of PMC function cards， compatible with semi-physical simulation， military testing， and other special scenarios
