The IC695RMX128 is a PACSystems RX3i redundant memory switch module. The main function of this module is to act as a single node on a reflected memory topology, or as a dedicated memory module for redundant RX3i CPU pairs. When used in a redundant CPU configuration, IC695RMX128 reflects the contents of IC695CMX128. With reflective memory linking, any update on one node is reflected and updated to all other nodes connected to the same network. The connection is established through a fiber optic network and supports connections of up to 256 nodes. The module comes with 128 MB of reflected memory, has a fiber optic power supply requiring LC type connectors and is designed to achieve transfer speeds of up to 2.12 Gbaud. The module operates on 580 mA@3.3VDC and 220 MA@5VDC power supplies. The IC695RMX128 is intended for redundant systems and cannot be used to perform general-purpose memory Xchange functions. In addition, a complete communication path must be established to complete the in-memory Xchange network. The complete communication path consists of a primary RMX unit and a 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. Because a dedicated RMX module must be used for redundant controller configuration, any redundant controller design does not have to use other RMX or reflective Nides. The configuration of RMX nodes is done through programming software rather than through jumper or DIP switch Settings. This ensures centralized modification of modules and minimizes hardware outages.

The IC695RMX128 memory module is a redundant memory module in GE Fanuc Automation’s RX3i PACSystems family. This module is particularly suitable for situations where there is a hot standby CPU redundancy system, where the second CPU acts as a backup device to the primary CPU, and there is a continuous data transfer between the two devices. The module runs on this reflective network and acts as a link between the two cpus. When this link is inactive or not currently in use, it is the same as the main module (that is, the IC695CMX128 module). GE Fanuc Automation IC695RMX128 Redundant memory module provides data sharing between different PCS and computing devices connected via a high-speed fiber optic network. This module has network error detection function. GE Fanuc Automation IC695RMX128 Redundant memory modules can be connected to other devices via fiber optic cables in Daisy chain rings. Transfers are performed from one node to another until they reach the final receiver. The module comes with 128 KB of reflected memory and a high-speed and easy-to-use 2.12 GBaud fiber network. The module occupies a slot in the RX3i rack. GE Fanuc Automation IC695RMX128 Redundant memory replacement module with zirconium ceramic ferrule with a maximum insertion loss rating of 0.35 dB and return loss. The input power of the module is 580 mah at 3.3 volts DC and 220 mah at 5 volts DC. The module can be plugged in easily and the system power is still on. This insertion mode is called jot insert and is suitable for some parts of the RX3i PacSystems family.
