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