Abstract: The process control system includes at least one master computer, at least one master system bus and at least one communication network, where the communications network is physically decoupled from the master system bus. The master computer is connected both to the master system bus and to the communications network and enables data exchange between the systems using Internet browser technology. At least one technical facility that is to be controlled can thus be advantageously controlled both by the master computer and by at least one computer connected to the communications network.

Abstract: According to the invention, a process control system comprises an image representation system (7) with which a process image may be distributed across several display devices (9). Said image representation system (7) comprises a graphic adapter (12), modified for determining the distribution of the process image on the display devices (9) in a internal memory (S) on the graphic adapter and to control the display devices (9) for display of the process image with the corresponding process image distribution data for each of the above.

Abstract: The process control system (5) according to the invention comprises at least one master computer (7), at least one master system bus (9,10) and at least one communications network (11), wherein the communications network (11) is physically decoupled from the master system bus (9,10). The master computer (7) is connected both to the master system bus (9,10) and to the communications network (11) and enables data exchange between said systems using Internet browser technology (70). At least one technical facility that is to be controlled can thus be advantageously controlled both by the master computer (7) and by at least one computer (47) connected to the communications network.
