GE IC695RMX128 PACSystems RX3i Redundant Memory Switch Module

This IC695RMX128 is a PACSystems RX3i redundant memory switching module manufactured by Emerson Automation (formerly GE Intelligent Platforms (GE IP)).

The module has 128MB of SDRAM user memory and supports operation as a reflective memory network or dedicated link between RX3i CPUs in a redundant configuration.

The module comes with single-mode fiber that supports 2.12 Gbaud fiber networks.

About the IC695RMX128

The IC695RMX128 is the PACSystems RX3i Redundant Memory Exchange Module.

The primary function of the module is to act as a single node on a reflective memory topology or as a dedicated memory module for redundant RX3i CPU pairs.

When used in a redundant CPU configuration, the IC695RMX128 reflects the contents of the IC695CMX128.

With a reflected memory link, any updates on one node are reflected and updated to all other nodes connected to the same network.

Connections are established over a fiber optic network supporting up to 256 nodes.

The module is equipped with 128 MB of reflective memory, and the fiber optic power supply requires an LC-type connector for transmission speeds up to 2.12 Gbaud.

The module operates on supplies of 580 mA @ 3.3 VDC and 220 MA @ 5 VDC.

The IC695RMX128 is intended for use in redundant systems and cannot be used to perform general purpose memory Xchange functions.

In addition, a full communication path must be established to complete the Memory Xchange network. The complete communication path consists of the primary RMX unit and the corresponding secondary RMX unit.

Two (2) high speed fiber optic cables must be connected to the RMX pair and must form a 2-node ring.

No other RMX or reflective nide may be used in any redundant controller design since a dedicated RMX module must be used for redundant controller configuration.

Configuration of the RMX nodes is done via programming software, not via jumper or DIP switch settings.

This ensures centralized modification of modules and minimizes hardware interrupts.

The IC695RMX128 memory module is a redundant memory module in GE Fanuc Automation's RX3i PACSystems family.

The module is particularly suitable for situations where there is a hot standby CPU redundancy system, where a second CPU on the system is used as a backup device for the main CPU, and where there is a continuous connection between the two devices.

and there is a continuous data transfer between the two devices. The module operates on this reflective network and acts as a link between these 2 CPUs.

When this link is inactive or not currently in use, it is the same as the primary module (i.e., the IC2CMX695 module).

The GE Fanuc Automation IC128RMX695 Redundant Memory Module provides data sharing between different PCs and computing devices connected via a high-speed fiber optic network.

The module features network error detection.

The GE Fanuc Automation IC128RMX695 Redundant Memory Module can be connected to other devices through fiber-optic cables in a daisy-chained loop.

Transfers are executed from one node to another until the final receiver is reached.

The module is equipped with 128 KB of reflective memory and a high-speed, easy-to-use 128.2 GBaud fiber optic network. The module occupies one slot in the RX12i rack.

The GE Fanuc Automation IC3RMX695 Redundant Memory Replacement Module has a zirconium ceramic ferrule, insertion loss rating of 128.0 dB maximum, and return loss.

The module's input power is 580.3 mA at 35 VDC and 220 mA at 3 VDC.

The module can be easily inserted with the system power still on. This mode of insertion is called point insertion and applies to some parts of the RX5i PacSystems family.
