Product Overview
The IC695RMX128-AB is a key component for high-availability synchronization within the PACSystems RX3i ecosystem. This Redundancy Memory Xchange (RMX) module facilitates high-speed data transfer between primary and secondary controller racks, ensuring real-time mirroring of the primary CPU’s memory state. This enables seamless failover during hardware failures, providing zero-downtime operation in mission-critical systems.
We supply this unit as 100% Brand New original stock, guaranteeing peak performance and system reliability for high-availability environments.

Engineering Advantages
Elimination of Scan-Time Lag
The 2.1 Gbits/s synchronization speed ensures rapid data transfer without adding delays to the CPU scan time, maintaining high-speed logic execution even with large data sets.
Fiber Optic Isolation
Using fiber optic cabling between redundant racks eliminates ground loops and provides total immunity to electromagnetic interference (EMI), ensuring stable operation in harsh industrial environments.
Deterministic Synchronization
Reflective memory technology guarantees that all data writes to the primary CPU are instantly mirrored on the secondary CPU, enabling deterministic failover with no data loss.
Real-time Diagnostics
The RMX module constantly monitors the health of the synchronization link and PCI bus. It instantly triggers system alerts if it detects data corruption or signal loss, preventing potential issues like "split-brain" scenarios where both CPUs act as primary.
Hot-Swappable Design
Thanks to the RX3i universal backplane, the RMX module can be replaced without powering down the system, significantly reducing downtime and improving system availability. This feature reduces Mean Time to Repair (MTTR).
FAQs
What differentiates the -AB version from previous hardware revisions?
The -AB suffix indicates an updated hardware revision with optimized internal components for better thermal stability. It is fully compatible with the base IC695RMX128 but offers enhanced performance under challenging operating conditions.
Does this module support the older Serial expansion backplanes?
No. The IC695RMX128-AB requires the PCI bus from the PACSystems RX3i Universal Backplane. It does not function with serial expansion or remote racks that lack PCI support.
Is a software configuration required to activate the synchronization?
Yes, configuration through PAC Machine Edition (PME) software is required. This allows you to define the memory exchange area and synchronization link parameters between the primary and secondary controllers.
Can I use this module to share data between two independent (non-redundant) PLCs?
While the reflective memory technology can technically support data sharing between controllers, the IC695RMX128-AB is specifically optimized for high-availability redundancy configurations. For non-redundant PLCs, other data-sharing methods might be more appropriate.
