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.
