General Electric IC695RMX128 Redundant Memory Xchange Module

GE IC695RMX128 is a Redundant Memory Xchange Module for RX3i systems, and can be used as a node in a reflective memory network or as a dedicated link between CPUs in an RX3i hot standby CPU redundant system. When not used as a redundant system link, its functionality is the same as the IC695CMX128 module, and RMX128 and CMX128 modules can be combined in the RX3i main chassis to support up to 6 memory exchange modules, of which up to 2 RMX modules can be configured as redundant communication links.

Function & Features

• Reflective memory network mode: After data is written to any node, it is automatically synchronized to all nodes in the entire network (delay in microseconds). IC695RMX128 supports dynamic data packets (4~68 bytes) with a transmission rate of 2.1 GByte/s.

• Redundant CPU link mode: IC695RMX128 is directly connected to the main/backup CPU rack (requires 2 RMX modules) through optical fiber to form an independent dual-node ring network. Dual-link configuration (4 modules) is recommended, and single-link (2 modules) is optional.

• Fiber network: 2.12 Gbaud rate, maximum transmission distance of multimode fiber 300 meters. Daisy chain topology, supports 256-node cascading.

• Zero CPU load: Data synchronization does not occupy PLC processing resources.
