Method for testing the functional stability of a controller of a refrigerating machine where the controller performs control cycles. The testing method comprises a step (100) of recording a set of current values of input variables, status variables and output variables of the controller, and a subsequent execution step (200), in which the values of the status variables and input variables recorded in the recording step are forced in the controller as inputs and values of the output variables are recorded in order to compare them with the values of the output variables recorded in the recording step (100).

The invention relates to a method and a system for determining process data of a work process carried out by an implement based on the determination of a moved mass by a weighing system of the implement and the detection of a parameter concerning a state of the implement and/or a work step, wherein with reference to these and further data a prediction value concerning the remaining part of the current work process is determined and on the basis of which information on the assistance is indicated to the operator of the implement, and to an implement comprising such a system.

An augmented reality (AR) system for diagnosis, troubleshooting and repair of industrial robots. The disclosed diagnosis guide system communicates with a controller of an industrial robot and collects data from the robot controller, including a trouble code identifying a problem with the robot. The system then identifies an appropriate diagnosis decision tree based on the collected data, and provides an interactive step-by-step troubleshooting guide to a user on an AR-capable mobile device, including augmented reality for depicting actions to be taken during testing and component replacement. The system includes data collector, tree generator and guide generator modules, and builds the decision tree and the diagnosis guide using a stored library of diagnosis trees, decisions and diagnosis steps, along with the associated AR data.

A work machine is disclosed. The work machine has a machine control for controlling the movements of the work machine in an operating mode of the machine control. The work machine also has a processing unit that has a detection unit. The detection unit is located on the work machine and is used to detect a target object within a safety zone. The processing unit sends a detection signal to the machine control when the target object is detected within the safety zone, and the machine control enters a safety mode from the operating mode when the detection signal is received. In the safety mode, the movement controls of the work machine are disabled.
