Product Overview

The IC695CMX128 is a specialized Control Memory Xchange (CMX) module designed for the GE PACSystems RX3i platform. Utilizing high-speed Reflective Memory technology, this module enables deterministic, real-time data sharing between multiple RX3i controllers and other CMX-enabled devices. It creates a "shared memory" pool across a fiber-optic network, ensuring that data written to one controller's memory is automatically and nearly instantaneously updated in all other nodes on the ring. We supply this module as 100% Brand New original hardware to guarantee peak communication performance for your synchronized control systems.

Engineering Advantages

• Ultra-Low Latency Determinism: The CMX technology provides sub-microsecond data transfers, completely bypassing the software overhead of traditional Ethernet protocols. This is critical for high-speed motion synchronization and multi-processor coordination.

• CPU Independence: Data exchange occurs at the hardware level. The RX3i CPU does not need to execute communication blocks or manage network "handshaking," preserving 100% of the processor’s resources for actual logic and control tasks.

• Automatic Data Replication: When the CPU writes data to a specific memory range assigned to the IC695CMX128, the hardware automatically multicasts that data to every other node on the ring. This creates a seamless "global" memory map across disparate PLC racks.

• Fiber Optic Noise Immunity: The use of fiber optic cabling provides total immunity to electromagnetic interference (EMI) and radio frequency interference (RFI). This allows high-speed data sharing across plant floors even in the presence of high-voltage equipment and variable frequency drives.

FAQs

Does this module require special software to configure?

Configuration is managed within GE PAC Machine Edition (PME). You define the memory offsets and node IDs directly in the hardware configuration settings of the RX3i project.

What type of fiber optic cable is required?

The IC695CMX128 typically uses Multimode fiber optic cabling with LC-style connectors. Ensure the cable specifications meet the 2.12 Gbaud bandwidth requirements for optimal performance.

Can this module be used for system redundancy?

While it facilitates high-speed data synchronization—a key component of redundancy—it is specifically a memory exchange module. For full CPU hot-standby redundancy, you should pair this with RX3i Redundancy CPUs (CRU series).

Is this a genuine and new product?

Yes. We guarantee the IC695CMX128 is 100% Brand New original stock. Every unit arrives in its original factory packaging with intact security seals to verify its authenticity and original specifications.
