IC695CRU320特別適用于冗余或雙機熱備配置。通過這種控制器配置，可用性顯著提高。兩(2)個配置功能類似的控制器機架，如主(活動)機架和輔助(備用)機架。當單個機架發(fā)生故障時，主要是由于IC695CRU320檢測到的錯誤或IC695CRU320處理器本身的錯誤，主動控制器的工作將自動轉(zhuǎn)移到次要(備用)。二級機架成為主機架，故障機架轉(zhuǎn)移到二級機架。此外，手動切換是可能的。
控制器切換的最大邏輯掃描次數(shù)為1次，最小切換時間為3.133 msec。它支持多達IC695RMX128/228的同步鏈路，能夠傳輸高達2mb的數(shù)據(jù)。憑借1GHz處理速度和64MB用戶內(nèi)存的賽揚M處理器，該控制器理想地用于具有更高臨界級別的大型復(fù)雜應(yīng)用程序。此外，多達512個程序塊可以保存到該處理器，每個塊的大小可以達到128 KB。
IC695CRU320有兩個獨立的串行端口和一個英特爾賽揚-M微處理器。它的64 MB非易失性閃存補充了64 MB電池供電的隨機存取存儲器(RAM)。IC695CRU320還支持本地和遠程擴展機架。CPU采用串行背板設(shè)計，與90-30系列I/O產(chǎn)品系列中的擴展模塊(但不是主機架)兼容。IC695CRU320使用Proficy Machine Edition，通用于所有GE Fanuc控制器的開發(fā)環(huán)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.
