It is therefore not possible to monitor operating data or to adjust operating data without direct contact with the system.

Furthermore, it is preferred that the evaluation of sensor data takes place using statistical methods and that historical data is compared and correlated with the sensor data determined in real time, in particular for the early detection of undesirable developments and maintenance events.
  • sensor data and/or process information is also used for predictive maintenance of wearing components. Based on statistical evaluations, manually stored maintenance and runtime intervals, as well as other data, an estimate can be made as to when a component in question, such as a drive or a bearing, is likely to fail. Service and maintenance work can advantageously be planned in an improved manner, taking this information into account.
