GE Fanuc Intelligent Platforms has announced a scalable high availability solution for its multi-domain PACSystems RX3i controller. Built on a synchronized hot-standby redundant control platform with transparent bumpless process switchover and easy configuration, PACSystems RX3i High Availability facilitates continuous uptime in essential applications such as water quality at water treatment plants, and wherever continuous uptime is essential to profitability.
To keep systems running efficiently and reliably, two independent controllers are connected on an RMX (Redundant Memory Xchange) reflective memory technology link providing up to 2 MB 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.
GE Fanuc’s patented 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. The systems can be located up to 300 meters apart to so that any localized event affecting one system does not affect the other.
