The GE Fanuc / VMIC VMIVME-5565 Reflective Memory Node Card is an optical ring-based, ultra high-speed shared memory network solution.
It allows a distributed network to share real-time data at a deterministic rate, regardless of bus structures and operating systems.
It is centered on an innovative and efficiently designed hardware platform that is easy to use, provides for greater distance between nodes, high noise immunity, optional node bypass, and no software overhead.
Just read and write to the onboard memory and the Reflective Memory node controller does the rest.
VMIVME-5565-11000 is a VME bus Reflective Memory node card from GE (formerly VMIC/GE Fanuc). Its core is used for low-latency data sharing in distributed real-time systems and supports fiber ring/star topologies.
It is commonly found in scenarios such as industrial control, aerospace, and test and measurement. The following are the core information and key parameters:
Core positioning and functions
Full name of the product: GE VMIVME-5565-11000 VME Reflective Memory Node Card (11000 is the configuration code, corresponding to the standard optical fiber interface and 128MB memory).
Core value: Achieve “real-time mirroring” of data among multiple nodes, software transparency and low latency (microsecond level), no need for complex protocol stacks, suitable for distributed control/simulation systems with high requirements for determinism and synchronization.
Typical applications: Gas/steam turbine control (for Mark VIe), substation automation, real-time simulation in aerospace, distributed test platform.
Key parameters and specifications
Project parameters/descriptions
The bus type is VME64. compatible with 32/64-bit and 33/66 MHz bus timing
Memory configuration: 128MB SDRAM (64MB is optional, corresponding to different configuration codes)
The optical fiber interface is available in single or multi-mode, with dual optical fiber ports (supporting redundancy)
The maximum non-redundancy transmission performance is 170 Mbyte/s (64 byte packets), and the maximum redundancy is 87 Mbyte/s
The maximum number of nodes is 256. supporting ring/star topologies
The connection distance for multimode optical fibers is ≤300m, and for single-mode optical fibers, it is ≤10km
The working environment is 0-55°C, meeting industrial-grade seismic and electromagnetic interference resistance standards
The typical power consumption is approximately 15W, powered by VME bus (+5V/+12V).
Key points for installation and integration
Bus adaptation: It is necessary to insert into a chassis slot that complies with the VME64 standard and verify the compatibility of the bus width (32/64 bits) and frequency (33/66 MHz).
Optical fiber connection: Redundant configuration requires a dual-fiber ring network, and the node sequence and port transceiver direction need to match the topology design.
Software support: Compatible with VxWorks, Linux, Windows and other systems, providing API and drivers, supporting interrupt triggering and DMA data transmission.
Replacement and compatibility: Interoperable with VMIPCI-5565/VMIPMC-5565 optical fibers of the same series. VME and PCI/PMC only differ in the bus interface, while the reflection memory protocol is the same.
