The General Electric IC698RMX016 is a high-performance Control Memory Xchange (CMX) module designed for the PACSystems RX7i platform. This module facilitates deterministic data sharing across PLCs and computing devices using high-speed reflective memory technology. It is engineered for demanding industrial environments, providing a reliable link for redundant systems and multi-node network architectures.

Features

• Single-slot form factor for PACSystems RX7i racks.
• 16 MB of reflective memory with parity support.
• High-speed 2.12 Gbaud fiber-optic network interface.
• Compatible with the VMIC 5565 family of reflective memory devices.
• Supports up to 256 nodes per network loop.
• Dynamic packet sizing (4 to 64 bytes) for optimized data throughput.
• Programmable VMEbus interrupt output with four general-purpose network interrupts.
• Software-configurable node parameters for flexible system integration.

Applications

• Power Generation & Utilities: Turbine control and plant monitoring requiring bumpless CPU transfer.
• Metal & Steel Production: Reliable operation in rolling mills and blast furnaces.
• Process Manufacturing: Synchronization of large data sets across cement, paper, and chemical processing nodes.
• Maritime & Shipbuilding: Propulsion and navigation control systems.

Technical Specifications

Installation Guidelines

• Ensure the rack power is completely switched off before inserting or removing the module to prevent electrical damage.
• The module is designed for installation in the main RX7i rack (Rack 0).
• Slots 3 and 4 are recommended to provide optimal VME interrupt request priority.
• Slide the module carefully into the designated slot; press firmly until seated.
• Tighten the screws on the top and bottom of the faceplate to ensure a secure mechanical connection and proper grounding.
• Handle with standard ESD precautions to protect sensitive internal components.

FAQs

What is the IC698RMX016?

It is a 16MB Redundant Memory Xchange module for the GE Fanuc RX7i PACSystem. It functions as a node on a reflective memory network or as a dedicated link between CPUs in a redundant system.

What is the data transfer rate?

The module utilizes a 2.12 Gbaud fiber-optic network, with effective transfer rates typically ranging between 3.2 MB/s and 6.2 MB/s depending on the redundancy density.

What type of connection does it use?

It utilizes a fiber optic LC-type connector (IEC 61754-20) with a zirconium ceramic ferrule.
