Product Introduction
GE IC698CMX016 VMIVME-5567-000 Overview
The GE IC698CMX016 VMIVME-5567-000 350-005567-000 is a Control Memory Xchange module designed for GE Fanuc PACSystem RX7i platforms. It uses reflective memory technology to distribute shared data between PLCs, VME devices, and compatible computing nodes through a high-speed fiber optic network.
The GE IC698CMX016 is used in systems where deterministic data synchronization is required, such as coordinated motion, simulation platforms, turbine control, and large-scale automation systems. It operates independently of CPU scan processing for network data exchange, but replacement requires verification of firmware revision, fiber topology, and reflective memory node configuration.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A production system has multiple controllers that must exchange data with precise timing. Suddenly, one section of the plant begins reacting slower than expected. PLC logic appears normal. The real issue is the communication layer.
Reflective memory networks are often installed in applications where timing matters. A failing fiber interface, incorrect node configuration, or damaged optical link can create intermittent synchronization problems that are difficult to diagnose.
The IC698CMX016 is not a standard communication card. It is part of the real-time data exchange architecture.
Typical Applications
- Power Generation – Turbine control systems, simulator platforms, and coordinated plant control networks.
- Manufacturing Automation – High-speed machine synchronization, robotic systems, and distributed motion control.
- Aerospace Test Equipment – Real-time simulation systems and measurement platforms requiring deterministic data transfer.
- Process Industries – Distributed PLC systems requiring fast data exchange between control stations.
Technical Pitfalls to Avoid
- Verify Reflective Memory Network Compatibility
The IC698CMX016 must communicate with compatible reflective memory nodes. Confirm that existing VMIC 5565/5567 family devices and network topology are supported before replacement.
- Check Fiber Optic Connections Carefully
Fiber contamination, damaged LC connectors, and incorrect transmit/receive routing are common causes of communication faults. Optical power testing should be performed before replacing hardware.
- Confirm Configuration Parameters
Node addresses, memory offsets, and network settings must match the existing system design. A replacement module can appear healthy while sharing incorrect data locations.
