Reflective memory technology allows transfer of large amounts of data at speeds up to 20 times faster than Ethernet
映射存储技术（RMX）允许大批量数据以高于以太网20倍的速度传输
CHARLOTTESVILLE, VA, JUNE 3, 2009 GE Fanuc Intelligent Platforms, a unit of GE Enterprise Solutions, today announced the introduction of its scalable high availability solution for the company’s industry-leading PACSystems® RX3i controller. By combining essential processes and capabilities onto one platform, the PACSystems RX3i controller is one of the most powerful, scalable, flexible, and efficient means to increasing productivity. It now adds high availability to its multi-domain functionality along with logic, motion, HMI, and process control.
Built on a synchronized hot-standby redundant control platform with transparent bumpless process switchover and easy configuration, PACSystems High Availability facilitates continuous uptime in essential applications.
GE Fanuc’s PACSystems RX3i High Availability is designed to keep essential systems running efficiently and reliably by connecting two independent controllers on our proven RMX reflective memory technology link providing up to 2 Mbytes of data synchronization. If an event occurs with the primary controller, the control functionality is automatically switched over to the redundant controller for continuous operations. It serves the needs of applications where continuous uptime is essential to profitability, where bottlenecks must be avoided, remote locations where time and cost to repair is extended, and operations where work stoppage means lost production. It can be found in areas as diverse as protecting critical information in data warehouses, ensuring water quality at water treatment plants, and keeping the power on for hospitals and surgery centers.
GE Fanuc的PACRX3i冗余系统通过在我们经过验证的RMX映射存储技术链接上连接两个独立的控制器提供高达2兆字节的数据同步以此来保持关键系统运行的有效性和可靠性。假若主控制器发生一个事件，控制功能将自动切换到冗余控制器实现持续的运行。这就在持续运行对利益率至关重要、必须避免堵塞、检修时间和成本扩大时遥控地点、工作中断意味着生产损失等情况下满足了应用和操作需求。此功能在关键信息在数据库中的保护、水处理厂水质量的保障及医院和手术室电力的保障等各种各样的场所都可能被发现使用。
With PACSystems High Availability, operations globally are delivering results for a sustainable competitive advantage:
◇Minimized downtime through robust, dual redundancy sync link

PAC冗余系统，整体操作呈递结果可持续的有竞争力的优势
◇可靠的双冗余同步链接实现停机时间最短化；
◇快速强大的同步及不间断的维持系统元素个体的能力保证了生产率的增加；
◇灵活的、可升级的、开放的结构最大程度的保护了用户投资；
◇简便的构造以及快速的启动和维持保证了时间的节省和工程开销的减少；
◇进的存储错误检测和修正（ECC）保证了数据完整性的增加。
PACSystems RX3i offers true dual redundancy data synchronization with dual modules and dedicated, redundant links to one another. They operate with virtually no overhead added to the control application. GE Fanuc’s unique, patented Redundant Memory Xchange (RMX) modules, based on reflective memory technology, synchronize the system at the beginning of the input scan and the end of output scan each logic scan execution to keep the controllers in lock step. Furthermore, the systems can be located up to 300 meters apart to so that any localized event affecting one system does not affect the other.
PACSystems High Availability is designed to operate as a single, complete system, therefore eliminating the complex preparations typically associated with synchronizing and data transfer. Configuration is made easy with a Redundancy Wizard that guides the user in setting up shared data and I/O for both systems in a matter of minutes.
PACSystems’ high speed memory sharing enables CPUs to be synchronized at 2.12 Gbits/second and multiple devices to transfer large amounts of data, up to 2 Mbytes, over a fiber optic deterministic network at speeds up to 20 times faster than Ethernet. The use of fiber optic connections allows users to easily operate in high-noise areas and cover large distances in real time.
“The PACSystems RX3i High Availability really maximizes return on investment,” said Bill Black, Product Manager for Controllers at GE Fanuc. “With minimized downtime in process, increased productivity with fast powerful synchronization, reduced engineering costs with easy configuration, and increased data integrity, all in the smaller footprint of the RX3i, customers really see the power of the system.” Seamlessly integrated into the system, the high availability continues to build out the incredible value of the entire PACSystems RX3i programmable automation controller.
