The VMIC -554 is a high-performance reflective memory board designed for real-time data sharing in industrial automation systems. As part of VMIC’s VMEbus product family, this module enables deterministic communication between multiple controllers with nanosecond-level synchronization. The VMIVME-5594 provides 256MB of shared memory space with <150ns access latency, making it ideal for mission-critical applications requiring time-sensitive data exchange.
Featuring fiber-optic connectivity, the VMIVME-5594 creates a low-latency network that maintains data integrity even in electrically noisy factory environments. Its dual-port architecture allows simultaneous access from both VMEbus and local processors.
