METHOD AND DEVICE FOR DETECTING AND EVALUATING PROCESS DATA

摘要

The invention relates to a method, a device and the use thereof for detecting and evaluating process data. According to the invention, in a plurality of processes, the curve of a measured value of at least one process parameter is detected via a control variable and the detected measured value curves are saved. Individual measured value curves can be quickly and adaptively evaluated when a group of curves is determined from the detected measured value curves and the frequency distributions of the measured values within intervals of the control variable are calculated from said group of curves.
