Product Function Description

IC698CMX016 VMIVME‑5567 is a dedicated reflective memory communication hardware for GE RX7i and VME bus systems. It builds a real‑time shared memory ring network through optical fiber, realizing hardware‑based memory mirroring among multiple nodes.

When one node writes data to local reflective memory, the hardware automatically synchronizes the data to all other nodes on the optical ring without CPU intervention. This deterministic transmission mode ensures low‑latency synchronous data updating for multi‑controller systems. The module supports daisy‑chain optical ring topology, and can be configured with redundant optical network to improve system reliability. It is widely used in occasions requiring strict real‑time performance such as turbine coordinated control and industrial simulation platform. IC698CMX016 is the GE PACSystems part number, and VMIVME‑5567 is the corresponding VME hardware part number.

Product Details

Standard 6U Eurocard single‑slot structure, directly plug‑in VME cabinet slot. Conformal coated circuit board adapts to harsh industrial environment with dust and electromagnetic interference. This legacy reflective memory module has been discontinued by original manufacturer, mainly used for old‑equipment maintenance and spare‑part replacement. Strict ESD protection shall be adopted during installation. Verify optical fiber parameter and node address configuration before commissioning.
