1. A system for industrial automation, the system comprising:
a cable;
an actuator device adapted to perform a movement by which the cable is set into a cable movement;
a field device having a function unit and a communication unit, the function unit being designed as an actuator unit, a sensor unit or a control unit and being further configured to provide a function in accordance with a received payload, and the communication unit being configured for receiving a payload signal containing the payload via the cable, wherein the communication unit comprises an equalizer unit and is configured to provide a parameter set on the basis of the payload signal, wherein the equalizer unit is configured to carry out signal equalization of the payload signal using the parameter set in order to obtain the payload from the payload signal; and
a diagnosis device the diagnosis device being configured to determine a cable wear condition of the cable in accordance with an indicator variable based on the parameter set,
wherein the diagnosis device is configured to detect movement information about the cable movement and to take the movement information into account when determining the cable wear condition, and
wherein the diagnosis device is adapted to detect the movement information based on the indicator variable.
