A system () for industrial automation, including a field device () with a function unit (), in particular an actuator unit, sensor unit and/or control unit, which is configured to provide a function in accordance with a received payload (ND), and a communication unit () for receiving a payload signal (DS) containing the payload (ND) via a cable (), the communication unit () being configured to provide a parameter set (PS) on the basis of the payload signal (DS) and to carry out signal processing of the payload signal (DS) using the parameter set (PS) in order to obtain the payload (ND) from the payload signal (DS), the system () further comprising a diagnosis device () which is configured to determine a cable wear condition of the cable () in accordance with an indicator variable (IG) based on the parameter set (PS).

System and method for determining a cable wear status

A valve arrangement () for industrial automation, including at least one pneumatic valve module () with a module housing (), the valve module () having a working port (), an electric drive device, and at least one actuator element () which is arranged in the module housing (), can be positioned, in particular proportionally, by means of the electric drive device and via whose position a valve module output pressure at the working port () and/or a flow rate through the working port () can be set, wherein the valve module () further has a valve module pressure sensor () for detecting the valve module output pressure, the valve arrangement () further including a diagnostic device () which is configured to provide a diagnostic function on the basis of the detected valve module output pressure, the diagnostic function including a failure prognosis of the valve module, a compressed air leakage detection, a compressed air consumption detection and/or a compressed air consumer localization.

Valve arrangement and method

An error detection and localisation in a pneumatic system and in particular an error detection module includes a read-in interface for reading-in digital signals from the automation plant, a first processor unit designed to execute a detection algorithm for calculating an anomaly score for the automation plant on the basis of the set of read-in signals, a second processor unit which is designed&#x2014;in the event that the anomaly score calculated with the first processor unit indicates an anomaly&#x2014;to perform a machine localisation method for localising the error, wherein the machine localisation method has been trained in a training phase in order to calculate and as a result provide, on the basis of a detected circuit diagram of the automation plant with respect to the calculated anomaly score, probabilities of possible causes of error in relation to individual components of the automation plant.
