Abstract

A method for the time-synchronized processing of data of a field device of process automation, in which the data and/or data changes are saved together with an internal time stamp of an internal timer of the field device in a memory of the field device; during the reading process of the data from the field device, a path difference being detected of the internal timer of the field device and a timer of the control unit by which the data is read, the internal time stamps are corrected by the path difference, and are saved as corrected time stamps together with the data.
