Abstract: The present invention provides systems and methods for controlling processes of a process facility and, in particular, for distributing data among nodes of a real time process control system controlling such a facility. An exemplary process control system includes a plurality of sensors, controllable devices, and communication paths, and a computer system. The sensors and controllable devices are associated with various ones of the processes of the process facility, and the communication paths couple the sensors and controllable devices to the computer system. The computer system operates on data related to the process facility, and distributes the data among both client and process nodes. The client nodes desire data associated with processes of the facility and the process nodes control such process data.
