Description
1. Product Description
The GE Fanuc IC695RMX128 is a high-performance redundancy memory exchange module designed for the RX3i PACSystems series, manufactured by Emerson Automation (formerly GE Intelligent Platforms). This module serves as a critical component in redundant controller configurations, enabling seamless data synchronization between primary and secondary CPUs. It supports a reflective memory network with up to 256 nodes, ensuring real-time data sharing via a 2.12 Gbaud single-mode fiber-optic network. The IC695RMX128 features 128 MB of SDRAM for user memory, hot-swap capability, and network error detection, making it ideal for mission-critical applications requiring high availability.

6. Selection Recommendations
- Compatibility: Ensure compatibility with RX3i systems and the IC695CMX128 partner module.
- Network Scale: Choose the IC695RMX128 for networks requiring >64 nodes (up to 256).
- Distance Requirements: Opt for this module if redundant controllers are spaced >200 meters apart.
- Budget: Balance memory capacity (128 MB) and speed (2.12 Gbaud) against project needs; suitable for medium-to-high complexity applications.
7. Precautions
-
Redundancy Setup: Use paired IC695RMX128 modules (primary/secondary) in a 2-node ring configuration. Avoid mixing with other RMX modules in redundant designs.
-
Installation: Follow RX3i rack slot guidelines; ensure proper fiber-optic cable termination (LC connectors).
-
Power Requirements: Verify 3.3 VDC/5 VDC power supply stability to prevent module failures.
-
Maintenance: Regularly inspect fiber-optic connections for damage; schedule firmware updates via GE Fanuc programming software.
