Technical Features & Benefits
The GE IC698CRE020 is purpose-built to support hot-standby redundancy within the PACSystems RX7i platform. Rather than relying on external networking or third-party hardware, it establishes a dedicated, high-speed synchronization path between two RX7i CPUs.
At a technical level, the module continuously mirrors application memory, I/O states, and critical system data from the active controller to the standby unit. This synchronization occurs in real time, ensuring that both controllers remain aligned during normal operation. If the primary CPU fails or is removed, the standby CPU transitions to active status without interrupting the control process.
One significant benefit of this design is determinism. Because the redundancy mechanism is hardware-assisted and tightly integrated with the RX7i backplane, failover timing is predictable and repeatable. Engineers responsible for safety-related processes often favor this approach over software-based redundancy schemes that depend on network latency or operating system behavior.
Another advantage is transparency to the application logic. Control programs do not require extensive modification to support redundancy. In most cases, standard RX7i applications run unchanged, while the GE IC698CRE020 handles synchronization and role management behind the scenes. This simplifies validation and reduces commissioning time.
From a reliability standpoint, the module is engineered for continuous operation. Industrial-grade components, robust connectors, and conservative thermal design allow it to function in high-duty control cabinets. Many installations run for years without the redundancy module requiring attention, which aligns well with the expectations of critical infrastructure operators.
