Abstract: A method for process control in a network centric process control system. The network centric process control system includes a plurality of nodes, wherein each node includes one or more control services being a separate executable running in a separate operating system process provided by a real time operating system thereof, wherein configuration data defining a communication interface for process data between the plurality of nodes has been received from an engineering node. The method includes publishing, by one or more of the plurality of controller nodes and plurality of device nodes, process data information in a middleware service, the process data information having an identity unique in the network centric process control system, a data type for process data, and process data, wherein the middleware service being a separate executable running in a separate operating system process provided by a real time operating system thereof, and subscribing, by the one or more of the plurality of nodes, to process data information published in the middleware service. A network centric process control system, a computer program, and a computer program product thereof are also presented.
