The VMIVME-5565 is a high-speed Reflective Memory (RFM) interface module developed by Abaco Systems (formerly GE Fanuc / VMIC).
This 6U VMEbus fiber-optic communication card enables deterministic, ultra-low latency data sharing between distributed VME systems. By using a hardware-based shared memory model rather than traditional network protocols, the VMIVME-5565 achieves sub-microsecond synchronization latency, making it ideal for real-time control and simulation environments.
The module supports multi-node reflective memory rings, allowing multiple CPUs to operate as a unified processing system with automatic data replication across nodes via fiber optic links. Its optical isolation also provides strong EMI immunity for industrial and aerospace environments.

Q1: How does the module ensure data integrity?
The VMIVME-5565 uses hardware CRC and parity-based error detection. Transmission errors can trigger automatic retransmission or CPU interrupts to maintain memory consistency.
Q2: Do I need special software drivers?
Although reflective memory appears as mapped system memory, dedicated RFM drivers are recommended for VxWorks, Linux, and Windows to manage interrupts and diagnostics efficiently.
