Description
The VMIC VMIVME-5576 is a high-performance VMEbus Fiber Optic Reflective Memory Module designed for real-time data sharing between distributed computer systems. It provides deterministic, high-speed communication by automatically replicating data written into local memory across all connected nodes in a fiber-optic network.
The VMIVME-5576 is widely used in industrial automation, aerospace simulation, defense systems, test & measurement platforms, and complex control systems requiring low-latency data synchronization. It supports up to 256 network nodes and uses a fiber-optic daisy-chain ring architecture for reliable distributed data exchange.
This 6U VMEbus module includes onboard SRAM reflective memory, interrupt capability, error detection, and high-speed fiber communication. It allows multiple VME-based computers to share process data without continuous CPU involvement, making it suitable for mission-critical real-time applications.
