Data written into one node's local reflective memory is automatically transferred to the other nodes on the network and stored at corresponding memory addresses.
The optical network supports fast data exchange between distributed systems while providing electrical isolation and strong immunity to electromagnetic interference.
A node can generate an interrupt in another node or across the network, allowing connected controllers to respond to important events.
The board supports a redundant transfer mode to improve data transmission reliability.
Independent DMA channels help move data efficiently between the VMEbus and reflective memory, reducing processor involvement.
- Distributed industrial control systems
- Real-time data acquisition
- Power generation and energy control systems
- Industrial simulation and test equipment
- Aerospace and defense test systems
- Motion control and high-speed machine coordination
- VME-based embedded computing platforms
It is used for high-speed, real-time data exchange between multiple computers and controllers in distributed control systems.
Reflective memory automatically replicates data written by one network node to corresponding memory locations on other connected nodes.
It uses high-speed fiber-optic serial communication.
The documented VMIVME-5565 family supports up to 256 network nodes.
The documented maximum is approximately 300 meters for multimode fiber and 10 kilometers for single-mode fiber.
