Patent ID: 8311651

Claim:
A process automation system for determining, monitoring or influencing different process variables or state variables in at least one manufacturing or analytical process, comprising: at least one control station; and a plurality of field devices, which measure, monitor or influence the process variables or state variables; wherein: in each said field device, at least one sensor for ascertaining a measured value of a process variable or state variable, or one actuator for influencing a process variable or a state variable by means of an actuating value, is provided; each said field device makes available to every other field device of the process automation system cyclically or acyclically ascertained, measuring-device-specific, measured values or actuating values of the process variable or state variable, so that all ascertained measured values or actuating values of the manufacturing or analytical process are available as information to each said field device; and said current information for all ascertained measured values or actuating values of the process variables or state variables is available to each said field device as a current process-state-vector.
