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.
