IC695RMX128 — RX3i Redundancy Memory Xchange Module
Brand:​ GE / Emerson Automation Solutions
Series:​ PACSystems RX3i
Type:​ 128 MB reflective-memory module for Hot Standby CPU redundancy
Key Technical Parameters
Memory and network
Function: data exchange and memory synchronization between redundant RX3i CPUs; also usable as a reflective-memory network node
User memory: 128 MB SDRAM reflective memory with parity
Network speed: 2.12 Gbaud (approximately 2.1 Gbit/s)
Maximum nodes per network: 256
Packet size: dynamic, automatically controlled by the RMX128 / RMX228 module
Network resolution: four networks of 32 bits each
Fiber interface (inputs / outputs)Two LC single-mode fiber ports, conforming to IEC 6                                      
Zirconium ceramic ferrule
Insertion loss: 0.35 dB maximum
Return loss: −30 dB
Maximum link distance: 300 m between redundant controllers
System integration
CPU firmware requirement: RX3i CPU firmware 5.70 or later (some sources cite 8.15 or later); CRU320 required in a redundancy system; PME version 5.90 SIM1 or later
Location: must be installed in the main RX3i rack on an RX3i universal (PCI) backplane; not compatible with IC694CHSxxx expansion bases
Slot count: one slot; up to six memory-exchange modules per main rack in an RMX/CMX mix; up to two RMX modules configurable as redundant links
Hot insertion and removal supported
Network error detection: CRC-based checking plus link status monitoring
LED indicators: Local READY, Local ACTIVE, Remote READY, Remote ACTIVE, LINK OK, FAULT
Companion modules: pairs with IC695CMX128 (master in a redundant set) and works with IC695RMX228 (256 MB version)
