A process control system includes a PC that is to be connected to a redundant network. The PC comprises a virtualization unit, and a real-time communication unit configured to operate as a separate process independent of the virtualization unit.

First claim

Opening claim text (preview).

What is claimed is: 1 . A process control system comprising: a PC that is to be connected to a redundant network, wherein the PC comprises a virtualization unit, and a real-time communication unit configured to operate as a separate process independent of the virtualization unit. 2 . The process control system according to claim 1 , wherein the real-time communication unit is configured to perform connection switching processing with the network. 3 . The process control system according to claim 1 , wherein the virtualization unit and the real-time communication unit are exclusively allotted with a CPU resource of the PC, respectively. 4 . The process control system according to claim 1 , wherein a guest OS and application software are configured to operate on the virtualization unit. 5 . The process control system according to claim 1 , wherein the process control system is configured to perform at least one of plant control and safety instrumentation control. 6 . The process control system according to claim 1 , wherein the virtualization unit and the real-time communication unit are placed on the host OS.
