This invention describes a method for detecting a misconfiguration of a machine function of a first industrial machine (M1). A set (N) of second industrial machines (MS) from said several other industrial machines (MO) is created by identifying a predetermined feature of the first industrial machine (M1) in several other industrial machines (MO). A first configuration value is created, which relates to the machine function of the first industrial machine (M1), and a second configuration value is created which relates to the machine function of the second industrial machines (MS). Depending on a relation of the first configuration value to the second configuration value a deviation value is determined by a configuration anomaly detection module (CADM). For detecting the misconfiguration of the first industrial machine (M1) the deviation value is compared with a predetermined threshold value.
