Emerson IC695RMX228 128 MB Single-Mode Reflective Memory Module
An RX3i reflective-memory module for deterministic shared data over a single-mode optical network.
Product Overview
IC695RMX228 is the PACSystems RX3i 128 MB Reflective Memory Module with a single-mode transceiver. It participates in a reflective-memory network that distributes shared data among configured nodes.
Emerson added CPE305 support for this module in firmware 8.15 and identifies PAC Machine Edition 8.50 SIM2 as the minimum configuration release in the controller documentation.
The optical mode is a critical selection boundary: IC695RMX228 must not be treated as the same physical network interface as a multimode reflective-memory module.
Performance
Shared-memory exchange
Replicates configured memory regions among network nodes without ordinary message polling.
Single-mode optical transport
Carries reflective-memory traffic through the approved single-mode fiber architecture.
Node and offset control
Uses configured node identity, memory mapping and interrupt behavior to coordinate participants.
Network diagnostics
Provides status information needed to confirm link continuity and data exchange.

FAQ
Q01
Is IC695RMX228 a multimode reflective-memory module?
+
No. Emerson identifies it as the 128 MB module with a single-mode transceiver.
Q02
What configuration should accompany a IC695RMX228 enquiry?
+
Provide node IDs, memory offsets, interrupt settings, CPU models and firmware, software release, fiber type and topology.
Q03
Can IC695RMX228 join an IC695RMX128 optical loop directly?
+
Do not assume direct compatibility: the optical mode and approved network architecture must be verified.
Q04
What software baseline is documented for configuring IC695RMX228?
+
Emerson controller documentation identifies PAC Machine Edition 8.50 SIM2 as the minimum configuration release.
Q05
What proves IC695RMX228 is operational after replacement?
+
Confirm clean link diagnostics, correct node identity, stable shared-memory updates and application-level synchronization.
