The GE IC695CMX128 is a Control Memory Xchange (CMX) module designed for the PACSystems RX3i platform, built to enable high-speed deterministic data sharing between controllers and distributed automation systems.
It uses reflective memory technology over fiber optic communication, allowing multiple PLCs and computing nodes to share a common memory space in real time. When one device writes data to memory, all connected nodes receive the update instantly without CPU intervention.
With 128 MB shared SDRAM, this module is widely used in synchronized multi-controller systems, motion control networks, and high-speed industrial automation architectures where latency-free data exchange is essential.
