Abstract: A method for monitoring an IO link system and/or at least one IO link device of the IO link system and/or a plant, a plant part and/or a process that works together with the IO link system is suggested. The current (Im), the voltage (Um) and/or the electrical power (Pm) are here recorded (42) at at least one port of an IO link master of the IO link system. A monitoring of a condition (Z) and/or a detection of anomalies, errors, deviations and/or maintenance indicators and/or a prediction of a maintenance requirement, an error and/or an outage of the IO link system and/or of the at least one IO link device and/or of the plant, of the plant part and/or of the process in the IO link master occurs by means of a model (M) for the current, the voltage and/or the electrical power previously learned via machine learning.

Abstract: In a method for parameterising at least one device (30), at least one environmental value (31) of the device is determined via at least one sensor and/or an automation component. It is checked whether parameters are allocated to the at least one environmental value in a parameter database (32). If parameters are allocated to the at least one environmental value (31) in the parameter database (32), the device (30) is parameterised with parameters from the parameter database (32). If no parameters are allocated to the at least one environmental value (31) in the parameter database (32), the device (30) is parameterised with new parameters. The new parameters are then allocated (54) to the at least one environmental value (31) in the parameter database (32).

Abstract: A method for detecting the position of a piston of a piston cylinder is provided. A microwave transmit signal is emitted in the direction of the piston and microwaves reflected from the piston are detected. The transmit signal is a modulated signal with a base frequency sinusoidally modulated at a modulation frequency. An evaluation of the phase between transmit signals and receive signals is performed. A phase determination at the baseband and a simultaneous phase determination at at least one sideband are also performed. The phase determination at the baseband is used for fine determination of the piston position and the phase determination at the at least one sideband is used for coarse determination of the piston position. Bandpass filtering on receive signals and evaluation transmit signals is performed with respect to the base frequency or an intermediate frequency. Bandpass filtering is performed with respect to the modulation frequency.
