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.
PACRX3i冗余系统提供真实的双冗余数据同步包括两个专用的相互冗余链接的单元。它们的操作实际上并没有额外增加控制器负担。GE Fanuc独一无二的专利,冗余存储Xchange(RMX)单元,基于映射存储技术,和系统在输入扫描和输出扫描均保持同步,执行每一个逻辑扫描来保持控制器的锁步状态。此外,系统可以安装在远离目标达300米的位置,这样任意局部事件对一个系统的影响不会波及到其他系统。
