The GE Intelligent Platforms IC695CMX128-DG is a high-speed Reflective Memory (RFM) interface module designed for the PACSystems RX3i controller platform. This module enables deterministic, high-speed data sharing between multiple RX3i controllers or other RFM-compatible devices in a real-time network. By using fiber optic technology to replicate a local memory map across all nodes on the ring, it provides sub-microsecond data latency, making it ideal for synchronized multi-chassis control systems and high-demand simulation environments.

Application Fields
The IC695CMX128-DG is frequently utilized in complex industrial applications requiring ultra-fast synchronization. Key application fields include flight and turbine simulators, high-speed automated assembly lines, large-scale power plant control, and distributed engine testing systems. It is the preferred choice for engineers building multi-CPU systems that must share vast amounts of data without the overhead and unpredictable latency of standard Ethernet protocols.
Product Instructions
To install the IC695CMX128-DG, insert the module into a universal slot of an RX3i backplane while the power is off. The module uses an LC-style fiber optic connector; ensure you use high-quality multimode fiber cables and maintain a clean connection to prevent signal loss. The network must be configured in a physical ring, where the “Transmit” port of one module connects to the “Receive” port of the next. Configuration is handled via GE’s Proficy Machine Edition software, where you define the memory offsets and interrupt parameters. Always ensure that the “Dark Fiber” detection and ring diagnostic LEDs are monitored during initial setup to verify network continuity.
FAQ: Common Questions and Answers
Q: Does this module require special drivers for the RX3i CPU? A: The IC695CMX128-DG is natively supported by PACSystems RX3i CPUs with compatible firmware versions. It is configured as part of the hardware configuration in the Proficy Machine Edition environment.
Q: What is the benefit of “Reflective Memory” over standard Ethernet? A: Unlike Ethernet, which uses a “request/response” protocol and is subject to collisions, Reflective Memory automatically replicates data written to its local RAM across all other nodes on the fiber ring with zero CPU overhead, ensuring deterministic, low-latency performance.
Q: Can I connect this RX3i module to a PC-based Reflective Memory card? A: Yes, the IC695CMX128-DG is compatible with other GE/Abaco Reflective Memory products, such as PCI or PCIe RFM cards, allowing for seamless data sharing between PLCs and industrial PCs.
