Abstract

A method for controlling an industrial process includes providing process data of the industrial process to an active instance of a control software as input, based on this input, updating an internal state of the active instance of the control software that is characterized by a set of internal variables of this active instance; based on this updated internal state, determining an output signal and outputting this output signal to at least one piece of equipment that is configured to alter a state, and/or a behavior, of the industrial process. The method further includes providing a prioritized subset of the internal variables that characterize the state of the active instance to at least one further instance of a control software that is configured to take over control of the industrial process in case of a failure and/or malfunction of the active instance.
