IC695RMX128 GE 冗余交换存储模块 充当冗余RX3i CPU对的专用内存模块

产品细节：IC695RMX128 GE 冗余交换存储模块 充当冗余RX3i CPU对的专用内存模块

IC695RMX128是PACSystems RX3i冗余内存交换模块。该模块的主要功能是充当反射内存拓扑上的单个节点，或者充当冗余RX3i CPU对的专用内存模块。

在冗余CPU配置中使用时，IC695RMX128反映IC695CMX128的内容。使用反射内存链接，一个节点上的任何更新都会被反射并更新到连接到同一网络的所有其他节点。通过光纤网络建立连接，支持多达256个节点的连接。

该模块配有128 MB反射内存和光纤电源，需要LC型连接器，设计传输速度高达2.12 Gbaud。当电源为580 mA @ 3.3 VDC和220 MA @ 5 VDC时，该模块运行。

IC695RMX128用于冗余系统，不能用于执行通用内存交换功能。此外，必须建立完整的通信路径来完成memory Xchange网络。完整的通信路径由主RMX单元和相应的次RMX单元组成。两(2)条高速光纤电缆必须连接到RMX对，并且必须形成一个双节点环。由于冗余控制器配置必须使用专用RMX模块，因此任何冗余控制器设计都不得使用其他RMX或反射nide。RMX节点的配置是通过编程软件进行的，而不是通过跳线或DIP开关设置。这确保了模块的集中修改并最小化硬件中断。

IC695RMX128内存模块是GE Fanuc Automation RX3i PAC systems系列中的冗余内存模块。该模块特别适用于存在热备用CPU冗余系统的情况，在该系统中，第二个CPU作为主CPU的备份设备，并且这两个设备之间存在持续的数据传输。该模块在这种反射网络上运行，并作为这两个CPU之间的链接。当该链路处于非活动状态或当前未被使用时，它等同于主模块，即IC695CMX128模块。GE Fanuc Automation IC695RMX128冗余内存模块在通过高速光纤网络连接的不同PC和计算设备之间提供数据共享。该模块具有网络错误检测功能。

GE Fanuc Automation IC695RMX128冗余内存模块可以通过菊花链环路中的光缆连接到其他设备。从一个节点到另一个节点执行传输，直到它到达最终的接收器。该模块配有128 KB的反射内存和高速易用的2.12 GBaud光纤网络。该模块占用RX3i机架中的一个插槽。GE Fanuc Automation IC695RMX128冗余记忆更换模块有一个锆陶瓷套圈，最大插入损耗额定值为0.35 dB，回波损耗。该模块的输入功率在3.3伏DC时为580毫安，在5伏DC时为220毫安。该模块可以在系统电源仍然打开的情况下轻松插入。这种插入模式称为快速插入，适用于RX3i PacSystems系列的某些零件。

IC695RMX128

The IC695RMX128 is a PACSystems RX3i Redundancy Memory Exchange Module. The main function of this module is to act as a single node on a reflective memory topology or as or as dedicated memory module for a redundant RX3i CPU pair.

When used in a redundant CPU configuration, the IC695RMX128 reflects the contents of the IC695CMX128. With a reflective memory link, any update on one node is reflected and updated to every other nodes connected to the same network. Connection is established via a fiber-optic network and supports connection of up to 256 nodes.

This module comes with 128 MB of reflective memory with a fiber optic power that requires LC type connector, designed for transmission speed of up to 2.12 Gbaud. This module operates when supplied with 580 mA @ 3.3 VDC and 220 MA @ 5 VDC.

The IC695RMX128 is used in redundancy systems, it cannot be utilized to perform general purpose memory Xchange capabilities. Additionally, a complete communication path must be established to complete the memory Xchange network. A 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. Since a dedicated RMX module must be used for redundant controller configuration, no other RMX or reflective nide must be used for any redundant controller design. Configuration of RMX node(s) is doe via the programming software, not by jumper or DIP switch settings. This ensure centralized modification of the module and minimizes hardware interruption.

The IC695RMX128 memory module is a redundancy memory module that comes in the RX3i PACSystems series by GE Fanuc Automation. This module is applied specifically where there is a hot standby CPU redundancy system on which a second CPU works as a backup device for the main CPU and there is a constant data transfer between these 2 devices. This module operates on this kind of reflective network and as a link between these 2 CPUs. When this link is inactive or when it is not being used currently, it is identical to the main module, which is the IC695CMX128 module. The GE Fanuc Automation IC695RMX128 redundancy memory module provides data sharing between different PCs and computing devices that are connected through a high-speed fiber-optic network. The module comes with network error detection features.

The GE Fanuc Automation IC695RMX128 redundancy memory module can be connected to other devices through fiber-optic cables in a daisy-chain loop. The transmission is performed from node to node until it reaches the final receiver. This module comes with a reflective memory of 128 KB and a high-speed and easy-to-use 2.12 GBaud fiber-optic network. This module occupies a single slot in the RX3i rack. The GE Fanuc Automation IC695RMX128 redundancy memory change module has a zirconium ceramic ferrule, an insertion loss rating of 0.35 dB maximum, and a return loss. The input power of this module is 580 milliamps at 3.3 Volts DC and it is 220 milliamps at 5 Volts DC. This module can be inserted in an easily and with the power to the system still on. This insertion mode is called jot insertion and applies to certain parts from the RX3i PacSystems series.
