The traditional embedded systems are expensive to adapt to the new requirements. The Personal Computer based systems offer alternatives for industrial controls. It reduces the capital cost and provides a solution for multiple applications. However, limitations of PC based controls should be resolved. PC operates on a non-real time OS with non-deterministic response to real time events and data. The real-time pre-emptive kernel for Linux uses Xenomai for better solution. A real-time 10GbE data exchange optical network using Xenomai extension for Linux is demonstrated. The hardware based on Intel_82599 10GbE Ethernet PCIe network card supports IEEE1588 standard for synchronization, deterministic response to real-time interrupts and events. The benchmark testing comprises multiple nodes and data sources, for data exchange among nodes, which would improve the performance of PC control systems. Data sources and consumers include time synchronization, hardware and software events broadcasting. A single fiber cable is used for exchange of measured status and calculated control data among nodes. Moreover, the open source Ubuntu Linux RTOS will help the future development.
