Method for determining a measuring point in time for a field device and corresponding field device in which a measuring point in time has been determined

摘要

A method and apparatus for determining a measuring point in time (tM), at which a measured value is to be produced by a field device of process automation technology, wherein the field device communicates its measured values at certain communication points in time (tK) over a field bus following a query from a central control unit with regard to the measured values of the field device. The communication point in time (tf) is approximated from at least two communication points in time (tK, t'K) and the measuring point in time (tM) is determined on the basis of the approximated communication point in time (tf).
