System and method for determining a cable wear status

A method for determining a cable wear condition of a cable of a system for industrial automation, wherein the system comprises an actuator device and a cable, wherein the actuator device performs a movement by which the cable is set into a cable movement, wherein the system further comprises a field device with a function unit, wherein the function unit is designed as an actuator unit, a sensor unit or a control unit, and wherein the field device further comprises a communication unit, wherein the communication unit comprises an equalizer unit, wherein the system further comprises a diagnosis device, the method comprising the steps of:

• the communication unit receiving, via a cable, a payload signal containing the payload;
• the communication unit providing a parameter set based on the payload signal;
• the equalizer unit performing a signal equalization of the payload signal using the parameter set to obtain the payload from the payload signal;
• the function unit providing a function according to the payload;
• and
• the diagnosis device determining the cable wear condition of the cable according to an indicator variable based on the parameter set,
• wherein the diagnosis device has a machine learning model, which maps the indicator variable to the cable wear condition and is adapted to determine the cable wear condition using the machine learning model.
