IC698CRE020 GE Fanuc CPU中央处理器

IC698CRE020是一个700 MHz的中央处理器，配有英特尔奔腾III微处理器 由GE Fanuc为RX7i系列制造。该CPU配备有 热备用冗余允许关键应用程序在任何单个组件出现故障时继续运行。热备用系统使用两个CPU。一个CPU是主动控制进程的活动单元，另一个是与活动单元同步的备份单元，可以在必要时接管进程。 为了实现冗余，IC698CRE020需要一个冗余内存交换模块(RMX)目录为IC698RMX016。它通常被配置为每个单元中的冗余链路。

　　IC698CRE020与任何其他RX7i CPU一样，安装有配置为启动和完成特定任务的软件程序。这些任务包括以实时模式控制设备、维护一般机器流程以及处理材料应用。的附加功能IC698CRE020包括10MBs的电池后备存储器和非易失性闪存、对大容量存储器的访问以及用户可配置的数据和程序存储器。自动定位符号变量与90-70系列离散和模拟I/O一样受支持。该CPU还支持90-70系列VME模块。为了避免丢失CPU RAM的可能性，建议保持一个例行程序，包括在适当的时候更换电池组。电池负责日历时钟、数据存储器和程序等操作在断电期间的整体稳定性。

　　The IC698CRE020 is a 700 MHz Central Processing Unit with an Intel Pentium III microprocessor manufactured by GE Fanuc for the RX7i Series. This CPU is equipped with Hot Standby Redundancy to allow critical applications to continue operating in case of failure in any single component. A Hot Standby system uses two CPUs. One CPU is the active unit that aggressively controls the process, and the other is a backup unit that is synchronized with the active unit and can take over the process when necessary. To accomplish redundancy, the IC698CRE020 requires a Redundancy Memory Xchange module (RMX) catalogued as IC698RMX016. It is normally configured as a redundancy link in each unit.

　　The IC698CRE020, like any other RX7i CPU, is installed with a software program configured to initiate and complete specific tasks. Such tasks include controlling the device in real time mode, maintaining general machine processes, and handling materials applications. Additional features of the IC698CRE020 include 10MBs each of battery-backed memory and non-volatile flash memory, access to bulk memory, and user-configurable data and program memory. Auto-located Symbolic Variables are supported as are 90-70 Series discrete and analog I/O. Series 90-70 VME modules are also supported by this CPU. To avoid the possibility of losing the CPU’s RAM, it is advisable to maintain a routine procedure that involves replacement of the battery pack in due time. The battery is responsible for the overall stability of operations like the calendar clock, data memory, and programs during the absence of power.
