Core Working Principle
Reflective Memory is essentially a distributed shared memory technology：
Each VMIVME-5565 board card has a completely synchronized local memory；
When any VME master writes data to the memory of this floor card， the hardware automatically broadcasts it via optical fiber to all other nodes in the ring network；
All nodes complete memory data synchronization within a few microseconds， and the upper-level program can directly read the local memory to obtain the full network real-time data；
It can issue global hardware interruption instructions, enabling multi-unit gas turbines and excitation control systems to achieve millisecond-level synchronous interlock control.
