GE Fanuc VMIVME-5565 VMIVME-5565-110000 Reflective Memory VME Board

The GE Fanuc VMIVME-5565-110000 Reflective Memory VME board is a high-performance data sharing solution that is primarily used to enable real-time data sharing between multiple independent systems (nodes). The following is a detailed description of the board:

Main Features:

High-speed, low-latency, deterministic interface: The board provides a high-speed, low-latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates up to 170 Mbyte/s.

Onboard SDRAM: Each Reflective Memory board can be configured with 64 MB or 128 MB of onboard SDRAM, providing fast read access times to stored data.

Data Transfer Mechanism: Data written to the local SDRAM is broadcast to other Reflective Memory nodes over a high-speed fiber optic data path. This data transfer between nodes is software transparent, so no additional I/O overhead is required.

Transmit and Receive FIFOs: During peak data rates, the transmit and receive FIFOs buffer data to optimize processor and bus performance, thereby maintaining high data throughput.

Network transfer rates:

Network transfer rates range from 43 Mbyte/s (using 4-byte packets) to 170 Mbyte/s (using 64-byte packets).

Fiber optic connections:

The board supports multimode fiber and single-mode fiber connections, with multimode fiber up to 300 meters and single-mode fiber up to 10 kilometers.

Data sharing mechanism:

Data written to the memory of one node is also written to the memory of all nodes on the network, enabling real-time data sharing.

Other features:

The VMIVME-5565-110000 Reflective Memory VME board also features a high-speed, easy-to-use fiber optic network (2.12 GbBaud serial) and VME transfer rates of up to 40 megabytes.
