General Electric IC695CMX128 PACSystems RX3i Control Memory Xchange Module

Description

The General Electric IC695CMX128 is a Control Memory Xchange module designed for the PACSystems RX3i platform. This module serves as a high-speed, deterministic data-sharing interface, allowing for seamless communication across a reflective memory network. It provides 128 Mbytes of user-shared memory, enabling rapid data synchronization between PLCs, industrial computers, and other compatible devices. When utilized in an RX3i Hot Standby CPU Redundancy system, it functions as a dedicated link between CPUs to ensure high-availability control.

Features

• 128 Mbytes of high-speed SDRAM user-shared memory with parity.
• High-speed reflective memory network support with a bus speed of 2.1 Gbits/sec.
• Compatible with the 5565 family of reflective memory devices.
• Supports up to 256 nodes on a single reflective memory network.
• Single-slot module design for efficient rack space utilization in the RX3i backplane.
• Automatic data updates across all network nodes whenever a write operation occurs.

Applications

• Automotive assembly and manufacturing lines.
• Power generation and distribution control systems.
• Chemical and pharmaceutical processing facilities.
• Oil and gas refinery automation.
• High-availability redundancy systems requiring rapid CPU synchronization.

Technical Specifications

Installation Guidelines

• Power Down: Always disconnect power from the RX3i rack before installing or removing the module to prevent electrical damage.
• Handling: Use proper ESD (Electrostatic Discharge) precautions when handling the module.
• Mounting: Ensure the module is fully seated in the backplane slot and secured using the integrated locking mechanism.
• Enclosure: To comply with EN 55011 and FCC Class A standards, the module must be installed within a properly grounded metal enclosure to mitigate radio frequency (RF) interference.
• Cabling: Ensure fiber-optic connections are clean and properly routed to avoid signal attenuation or mechanical stress.
