IC695CRU320 GE 冗余处理器

IC695CRU320是PACSystems RX3i产品系列的冗余处理器。该处理器由GE发那科/艾默生自动化制造，被归类为可编程自动化控制器(PAC)。

IC695CRU320特别适用于冗余或双机热备配置。通过这种控制器配置，可用性显著提高。两(2)个配置功能类似的控制器机架，如主(活动)机架和辅助(备用)机架。当单个机架发生故障时，主要是由于IC695CRU320检测到的错误或IC695CRU320处理器本身的错误，主动控制器的工作将自动转移到次要(备用)。二级机架成为主机架，故障机架转移到二级机架。此外，手动切换是可能的。

控制器切换的最大逻辑扫描次数为1次，最小切换时间为3.133 msec。它支持多达IC695RMX128/228的同步链路，能够传输高达2mb的数据。凭借1GHz处理速度和64MB用户内存的赛扬M处理器，该控制器理想地用于具有更高临界级别的大型复杂应用程序。此外，多达512个程序块可以保存到该处理器，每个块的大小可以达到128 KB。

IC695CRU320有两个独立的串行端口和一个英特尔赛扬-M微处理器。它的64 MB非易失性闪存补充了64 MB电池供电的随机存取存储器(RAM)。IC695CRU320还支持本地和远程扩展机架。CPU采用串行背板设计，与90-30系列I/O产品系列中的扩展模块(但不是主机架)兼容。IC695CRU320使用Proficy Machine Edition，通用于所有GE Fanuc控制器的开发环境。

IC695CRU320

The IC695CRU320 is a Redundancy Processor from the PACSystems RX3i product family. This processor is manufactured by GE Fanuc / Emerson automation that is categorized as Programmable Automation Controllers (PAC).

The IC695CRU320 is especially used in redundant or hot-standby configuration. With this controller configuration, availability is significantly increased. Two (2) controller racks with similar configuration functions as Primary (active) and Secondary (stand-by) rack. When a single rack has failed, primarily due to errors detected by the IC695CRU320 or error of the IC695CRU320 processor itself, active controller duty is automatically transferred to the secondary (stand-by). The secondary rack becomes the primary and the failed rack shift to secondary rack. Additionally, manual switchover is possible.

Controller switchover is performed in Maximum of 1 logic scan with minimum switchover time of 3.133 msec. It supports up to IC695RMX128/228 synchronization links and capable of transferring up to 2Mbytes of data. With the Celeron M processor with 1GHz processing speed and 64MB user memory, this controller is ideally used in large and complex applications with increased level of criticality. Additionally, up to 512 program blocks may be saved to this processor which each block size may reach up to 128 KB.

The IC695CRU320 processor is installed to an RX3i backplane, directly to the Peripheral Component Interconnect (PCI) slot. Other module connections to the bus are also through the PCI 2.2 version or higher. This PCI slot enables rapid transfer and sharing of data within the backplane. The IC695CRU320 also supports Series 90-30 I/O modules for phased migration.

The current requirements for the GE Fanuc IC695CRU320 CPU are 1 Amp at 3.3 Volts DC and 1.2 Amps at 5 Volts DC. Two integrated serial ports are available on the module and they support RS-232 and RS-485 communication, respectively. A maximum of 512 program blocks that are configurable wherein up to 128 KB in size per block are supported. The rated flash memory endurance rating is 100,000 write/erase cycles at a minimum. The switchover time is 3.133 milliseconds at a minimum and 1 logic scan at maximum. The maximum amount of data that can be in transfer at a time is up to 2 MB. The IC695CRU320 CPU supports up to two IC695RMX128/228 synchronization links for redundancy. The programming of the IC695CRU320 CPU can be done in the ladder, C, and function block diagram languages. Ethernet communication is supported through the rack-based Ethernet communication module.
