IC695RMX128 Redundant memory exchange module

Description

The IC695RMX128 Module is a redundancy memory xchange module that has been designed by GE Fanuc Automation and included in the RX3i PACSystems series. The main purpose of this module is to operate as a node on a reflective memory network or as a dedicated link between CPUs in a hot standby CPU redundancy system. When used in the first instance, the module provides deterministic data sharing among PLCs and other computing devices connected to the optic network. When it is used in a redundancy system, this module provides a path so that data can be transferred between 2 redundancy CPUs in a redundant system. This last mechanism consists of 2 CPUs that work with identical functions whose main objective is to act as the backup CPU for each other. The GE Fanuc Automation IC695RMX128 Redundancy Memory Xchange Module has been designed to be used in an RX3i PACSystems rack. In this rack, a total of 6 memory exchange modules can be installed in any combination.

Some of the features of the GE Fanuc Automation IC695RMX128 Redundancy Memory Xchange Module are a reflective memory capacity of 128 MB, software configuration support for each node parameter, and a high-speed easy-to-use 2.12 Gbaud Network. The module is also compatible with the VMIC 5565 family of reflective memory devices. The GE Fanuc Automation IC695RMX128 Redundancy Memory Xchange Module provides a maximum network transfer rate of 2.1 GB per second according to the programmable module interrupt output level that is allowed. This module also provides network error detection features and a configurable network memory offset feature that enables the users to assign nodes on a specific network to groups according to the 16 MB segments that are available in the network address space.
