Process automation system for determining, monitoring and/or influencing different process variables and/or state variables

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, comprising:

• at least one control station;
• and
• a plurality of field devices, which measure, monitor or influence the process variables and/or state variables;
• wherein:
• in each said field device, at least one sensor for ascertaining a measured value of a process variable and/or state variable, and/or one actuator for influencing a process variable and/or a state variable by means of an actuating value, are/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 and/or actuating values of the process variable and/or state variable, so that all ascertained measured values and/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 and/or actuating values of the process variables and/or state variables is available to each said field device as a current process-state-vector.
