Abstract
Exemplary embodiments for configuring a system for monitoring the performance of a control loop of an industrial plant includes reading in first process data derived from measurements of at least one sensor inside the control loop during a specified control situation, calculating from the first process data a corresponding at least one performance index indicating the behaviour of the control loop and determining a first quality of the control performance depending on the difference between the at least one performance index and a corresponding threshold value. In case that the first quality of the control performance is determined to be less than good, a second quality of the control performance is determined either by calculating the second quality from an analysis of second process data or by processing a user input from a user of the system which indicates the second quality.
