GE IC695CMX128 RX3i Control Memory Xchange Module

Product Introduction

The GE IC695CMX128 RX3i Control Memory Xchange (CMX) Module is an advanced high-speed data sharing module designed for GE’s PACSystems RX3i control platform. It provides a powerful mechanism for real-time deterministic data transfer between multiple controllers without the need for traditional communication protocols. The module allows direct memory-to-memory data exchange between connected controllers using reflective memory technology, ensuring data synchronization across distributed control systems with microsecond-level latency.

This module is typically used in high-performance industrial automation systems, where coordinated control and precise data synchronization between multiple controllers are required. Its large 128 MB reflective memory capacity enables fast and efficient communication in complex control architectures.

The IC695CMX128 supports fiber-optic communication over long distances, ensuring robust performance even in electrically noisy environments. It is ideal for applications such as power generation, turbine control, paper and pulp systems, and process industries, where system integrity and deterministic performance are critical.
