The GE VMIPCI-5565 High Speed Transport Reflective Memory card is a real-time networking product from GE Fanuc Embedded Systems and is a PCI member of the VMIxxx-5565 family of Reflective memory (RFM). The following are the detailed features and information about the memory card:

Main features:

High-speed Fiber networks: Support high-speed, easy-to-use fiber networks with serial rates up to 2.12 Gbaud.

Data sharing: Data written to the memory of one node is also automatically written to the memory of all nodes on the network, allowing data to be shared between up to 256 nodes.

Transmission distance: The connection with multi-mode fiber can be up to 300 meters, and the connection with single-mode fiber can be up to 10 kilometers.

Dynamic packet size: Supported packet lengths range from 4 to 64 bytes, and transfer rates range from 47.1MB/ s (4-byte packets) to 174MB/ s (64-byte packets).

Memory configuration: Provides 64MB or 128MB of SDRAM reflected memory.

Technical specifications:

DMA channels: Two independent DMA channels support efficient data transfer.

Interrupt capability: Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command.

Error detection: Provides error detection to ensure the reliability of data transmission.

Redundant transmission mode: Provides redundant transmission mode to further suppress errors and improve the fault tolerance of the system.

Processor no overhead: The processor does not participate in network operation, reducing the processing burden of the system.

PCI Compatibility: Support for PCI 64-bit 66MHz transmission, compliant with PCI Revision 2.2.

Application and compatibility:

Real-time data sharing: Allows computers, workstations, programmable logic controllers (PLCS), and other embedded controllers with different operating systems or no operating systems at all to share data in real-time.

Cross-platform compatibility: Compatible with multiple operating systems, including WindowsNT, Windows 2000, VxWorks, and Linux.

Wide applicability: Suitable for real-time applications such as simulation and training, industrial process control, data flow and acquisition, as well as for high availability redundancy in commercial, telecommunications and military & aerospace.
