Abstract
A method for reducing an amount of process data to be transferred from a field device, wherein the process data includes information concerning an operating condition of the field device, and/or information concerning process variables registered with the field device, and/or identification data of the field device. It is provided that process data occurring during an interval between two transfers of data is evaluated and stored, wherein the process data are reduced through the evaluating, and wherein the reduced process data is transferred to a process control station.

A method for reducing an amount of process data to be transferred from a field device, the process data including information concerning the operating condition of the field device, and/or information concerning process variables registered with the field device, and/or identification data of the field device, comprising the steps of
- evaluating and storing the process data occurring during an interval between two transfers of data, wherein the process data are reduced by means of the evaluating;
- and
- transferring the reduced process data to a process control center.
An apparatus for reducing an amount of process data to be transferred, wherein the process data includes information concerning an operating condition of the field device, and/or information concerning process variables registered with the field data of the field device, comprising:
- an evaluation/control unit;
- and
- a storage unit, wherein:
- said evaluation/control unit, during an interval between two transfers of data, evaluates and stores the acquired process data in said storage unit, and, by means of suitable communication units, transfers such process data to a process control center.
