Achieving Real-Time Performance on a Virtualized Industrial Control Platform
Virtualization has increased equipment utilization and lowered costs in data centers. Now the technology is making its way into industrial controllers. Equipment developers can consolidate real-time and non-time-critical applications onto a single board to streamline operations, improve productivity, and reduce cost and complexity, thanks to advances in real-time operating systems (RTOSs), lightweight hypervisors, and hardware-assisted virtualization that boost system responsiveness. There is a concern these platforms cannot deliver the real-time and deterministic response required by advanced automation processes. This paper explores this question by measuring the interrupt latency of the Intel Industrial Solutions System Consolidation Series—a virtualized platform for industrial workload consolidation.
