IC698RMX016-ED GE Redundancy Memory Xchange Module

Description

The Redundancy Memory Xchange (RMX) module operates as a node on a reflective memory network or as a dedicated link between CPUs in a redundant RX7i system. When the RMX is not being used as a link in a redundancy system, it is functionally identical to the IC698CMX016 module. Each node in the network can be any reflective memory device that is compatible with the 5565 family. Whenever data is written to one node, all nodes on the network are automatically updated with the new data. 

When used as a node on a reflective memory network, the RMX module provides deterministic sharing of data among PLCs and other computing devices on a high-speed fiber optic network. A reflective memory network can contain up to 256 nodes.  

Feature

16 Mbytes Reflective Memory with parity for error detection.

Software configuration for node parameters, eliminating the need for jumpers or switches.

High-speed fiber-optic network running at 2.12 Gbaud, with easy connectivity via multimode fiber (up to 300m / 984.25ft).

Network compatibility with the VMIC 5565 reflective memory devices.

Maximum transfer rates of 43 Mbyte/s (4-byte packets) to 174 Mbyte/s (64-byte packets).

No CPU processing required, ensuring the network operates independently of the RX7i CPU.

Application

The 120 volt AC Input module for the programmable controller provides 32 input points in four isolated groups of eight points each.  This allows each group of eight points to be used on a different phase of the AC supply. The input is reactive (resistor/capacitor input) with current-voltage characteristics which meet IEC standard (type 2).  The input characteristics are compatible with a large range of available proximity switches. LED indicators which give the ON-OFF status of each point on the logic (PLC) side of the circuit are included at the top of the module. The module is mechanically keyed to ensure correct replacement with a similar type in the field.
