Two operating systems on one device
21 August 2017
B&R is introducing a hypervisor for its automation system. This software allows Windows or Linux to run alongside B&R's own real-time operating system.
That enables you to combine the control and HMI applications on a single PC, for example, or have an industrial PC double as both a real-time controller and an edge controller that sends pre-processed data to higher level systems and the cloud via OPC UA.
The hypervisor provides a virtual network connection that allows applications to exchange data between operating systems. Like with the usual Ethernet interface, this is done using standard network protocols. In place of a cable, there is a reserved memory area that is not assigned to either operating system.
The user configures the hypervisor and allocates hardware resources in the B&R Automation Studio software development environment. The configurations are defined separately for each system, providing maximum flexibility in how resources are utilised. Whereas previous parallelisation solutions were tailored to a specific Windows version, B&R's hypervisor is completely independent of which operating systems are used.
