A process control apparatus includes a virtualization unit configured to operate in hardware, first and second operating systems configured to run in the virtualization unit, an application configured to run in the first operating system, and configured to control an industrial process by communicating with field devices, a recording unit configured to record a first information required for restoration of the application and a second information passed between the first operating system and the application, and a restoration unit configured to use a history of the second information to set the second operating system to the same state as the internal state of the first operating system, and configured to use the first information to restore the application running in the first operating system into the second operating system.

A system provides a design interface for designing and implementing graphical user interfaces that users can access through web browsers. Depending on the configuration of the graphical user interfaces, the users may be able to monitor and control industrial processes by interacting with components that correspond to the industrial processes as displayed in user interfaces at client devices. The design interface includes functionality for selecting preprogrammed components, or for generating new components for display. The design interface further allows designers to associate data values received from a variety of sources with properties of the components in the user interfaces. In particular, properties associated with a component of an interface are stored in property tree structures, making dynamic changes to the components possible. Data bindings between subtrees representing components and sets of data from industrial and other sources allows for designs that scale with the availability of the data.

A process controller includes a first virtualizer to run in a first process controller and a first operating system to run on the first virtualizer, the first operating system transiting from a first state to a second state when control of an industrial process is started. The first operating system transits from the second state to the first state when control of the industrial process for one period ends, the first state being waiting for starting the control of the industrial process, and the second state being when the industrial process is performed. An application runs on the first operating system and performs control of the industrial process at a constant period. A saving unit saves information representing an inner state of the application when the first operating system is in the first state, the information restoring the application in a second process controller different from the first process controller.
