GE VMIVME5565 332-015565-010 Reflective Memory Node Card

Configured for ultra-low-latency data replication and deterministic multi-node synchronization within VMEbus platforms, the GE Fanuc VMIVME5565 332-015565-010 (VMIVME5565 Reflective Memory Node Card) provides direct physical/electrical execution. It mirrors local onboard memory structures across distributed computing nodes via dedicated fiber-optic rings natively at the hardware tier to maintain real-time shared databases parallel to master processor bus execution cycles.

Hardware Specifications

Deterministic Industrial Control & Drive Processing Architecture

• Backplane Bus Communication Velocity and Registration: The VMIVME5565 implements an autonomous hardware-driven reflective memory ring that operates completely independent of host CPU processing overhead. When a local node writes data to its internal SDRAM array via the VMEbus, the onboard transmitter instantly encapsulates the change into a dynamic 4-to-64 byte hardware packet and broadcasts it down the fiber ring, updating adjacent nodes within 500 nanoseconds.
• Profinet / EtherNet/IP and Network Token Synchronization: Unlike standard master-slave token networks or industrial Ethernet configurations that suffer from software-stack latency and packet collisions, this fiber-optic card uses a continuous hardware ring topology. This configuration guarantees predictable sub-microsecond synchronization windows across distributed simulators, turbine control systems, and high-speed data acquisition assemblies.
• Firmware Flash Compatibility and Error Management: The board's integrated logic matrix tracks link integrity and handles active packet validation continuously at the physical tier. If a data packet gets corrupted or dropped over the network, the card's error management subsystem detects the parity exception, manages retransmission framing, and can trip a dedicated hardware interrupt to safeguard the validity of the global shared database.

Frequently Asked Questions

Q: What specific hardware states occur if an active fiber-optic cable is disconnected from a VMIVME5565 ring node?

A: The board's physical layer transceivers immediately flag a loss-of-signal (LOS) state, set an unmasked link-fault bit in the local status register, and illuminate the front-panel error LED. To prevent network isolation in critical safety setups, an external hub or dual-ring bypass module must be paired with the card to close the loop automatically.

Q: Can this 6U VMEbus reflective memory board be pulled from the chassis rack while power lines are live?

A: No. Standard VMEbus specifications do not support live hot-swapping. Extracting this node card while the backplane is energized creates transient signal noise and voltage arcs across adjacent bus pins, risking corruption of the shared memory registers and freezing parallel processing tracks on neighboring CPU nodes.
