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: 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.
