A method for event-oriented transmission of measured process values includes receiving the measured process values via an automation device of a control system of a process plant; automatically performing sensitization or desensitization of a measurement range of the measured process values on the automation device where, during sensitization or desensitization and depending on an undershoot of a minimal transmission rate of the measured process values from a measurement device to the automation device or an overshoot of a maximum transmission rate of the measured process values from the measurement device to the automation device, the measurement range is automatically decreased during sensitization and increased during desensitization by the automation device via a heuristic method, and transmitting the measured process values, on an event-oriented basis, to the operator station server of the control system of the process plant, where an event represents a predetermined change to the measured process values.

Various embodiments include a computer-implemented method for determining a level of wear of a tool. The method includes: obtaining an image data set mapping a wear-relevant region of the tool; allocating, using a computing unit and an artificial neural network, one class of a predetermined quantity of classes to each image point of a plurality of image points of the image data set; and determining a characteristic value based on a result of the allocation for the level of wear. The quantity of classes includes at least one wear class.

In a method for training a neural network to recognize a tool condition based on image data, the neural network is trained to recognize the tool condition of a first tool type, and image data of a second tool type is applied. The image data is subjected to image processing. Via this, the image data of the second tool type is converted into image data of the first tool type. The neural network is trained based on the converted image data. In a method for machining and/or production via the first tool type, the tool condition of the first tool type is recognized via a neural network that is trained in accordance with such a method.
