IC698RMX016 and VMIVME-5567-100: High-Speed Reflective Memory Solutions for Industrial Automation
1. Product Description
The IC698RMX016 (GE Fanuc RX7i PACSystem) and VMIVME-5567-100 (GE Fanuc VMIC) are high-performance reflective memory modules designed for industrial automation systems. These modules enable deterministic data sharing across distributed networks, supporting applications such as redundant CPU systems, real-time control, and high-speed data synchronization. The IC698RMX016 operates as a node on a reflective memory network or links two CPUs in a redundant setup, while the VMIVME-5567-100 serves as a reflective memory interface for VMEbus systems. Both models leverage fiber-optic technology for fast, reliable data transfer, with support for up to 256 nodes in a daisy-chained loop configuration.

- Scalability: Support for up to 256 nodes in a fiber-optic loop allows flexible network expansion.
- Easy Integration: Compact design and standardized interfaces (LC connectors, VMEbus) simplify installation in existing racks (e.g., RX7i rack 0 for IC698RMX016).
- Low Maintenance: Solid-state design with no moving parts minimizes downtime and repair needs.
4. Application Areas and Use Cases
- Industry: Manufacturing, energy, aerospace, and automotive.
- Applications: Real-time control systems, redundant PLC setups, distributed data acquisition, and high-speed machine synchronization.
- Case Study: A manufacturing plant uses the IC698RMX016 to link two redundant CPUs in a packaging line. The module ensures seamless data replication between CPUs, enabling zero downtime during maintenance and reducing production losses by 30%.
5. Competitor Comparison
Compared to similar reflective memory modules, the IC698RMX016 and VMIVME-5567-100 offer:
- Higher Bandwidth: 2.1 GB/s (IC698RMX016) vs. typical 1–1.5 GB/s in legacy systems.
- Redundancy Specificity: Dedicated support for hot standby CPU pairs (IC698RMX016), a feature not universally available in generic reflective memory modules.
- Compatibility: Native integration with GE Fanuc’s RX7i PACSystem and VMEbus platforms, reducing configuration complexity.

6. Selection Recommendations
- Compatibility: Ensure compatibility with your system (e.g., RX7i CPU firmware ≥ 2.00 for IC698RMX016; VMEbus for VMIVME-5567-100).
- Memory Needs: Choose IC698RMX016 (16 MB) for large data sharing; use VMIVME-5567-100 (1 MB) for compact, cost-sensitive applications.
- Environment: Verify temperature and EMI/EMC compliance (e.g., metal enclosures for RX7i systems with multiple modules).
7. Precautions
- Installation: Power off the system before installing modules. Route fiber-optic cables in a closed loop (TX to RX of the next node).
- Configuration: Use GE Fanuc’s CIMPLICITY Machine Edition software (version ≥ 4.5) for parameter setup (node ID, memory offset).
- Maintenance: Regularly inspect fiber-optic connections for damage. Avoid exposing modules to moisture or extreme temperatures.
