Abstract: A safety system for safeguarding cooperative operation of people, robots, and machines with respect to a technical installation includes a safety-related device. The safety-related device is configured to monitor a first hazardous area of the technical installation and bring the technical installation into a safe state in response to detection of a hazardous condition. The safety system is configured to identify an autonomously operating technical unit, register the autonomously operating technical unit in response to the autonomously operating technical unit satisfying a defined condition, and restrict monitoring of the first hazardous area by the safety-related device in response to the registration. The safety system is configured to, in response to a defined event, revoke the registration of the autonomously operating technical unit and lift the restriction on monitoring.

Abstract: An electronic safety switching device comprising at least a first and a second signal processing channel to which input signals may be supplied for signal processing. The first and second signal processing channels provide processed output signals, wherein the first and the second signal processing channels process the supplied input signals redundantly with respect to one other. The first and the second signal processing channels are each formed as integrated circuits, wherein the first signal processing channel is arranged monolithically on a first semiconductor substrate, and the second signal processing channel is arranged monolithically on a second semiconductor substrate. Furthermore, the first and the second semiconductor substrates are combined into a stack to form a one-piece electronic component.

Abstract: A safety system for safeguarding cooperative operation of people, robots and machines with respect to a technical installation, comprising a first safety-related device which is configured to monitor a first hazardous area of the technical installation and to bring the technical installation into a safe state if a hazardous condition is detected. The safety system is further configured to identify an autonomously operating technical unit and to register the autonomously operating technical unit when it satisfies a defined condition. Further, the safety system restricts monitoring of the first hazardous area by the first safety-related device in response to the registration.

Abstract: A new method and to a new programming tool for creating a user program for a safety controller is disclosed. The new method and programming tool exploit a matrix-type organization of occurring programming tasks. Itemized software components allocated to specific hardware components are combined with aspect blocks that enable programming grouped according to functional control aspects of the system to be controlled.

Abstract: A network having a plurality of subscribers has at least one message transmitter and at least one message receiver. The at least one message transmitter sends messages at predefined time intervals. The message receiver receives the messages at the predefined time intervals. A delay time of the messages is monitored on the basis of time outs. In addition, at least one of the subscribers repeatedly estimates a current delay time using a time measurement between sending out a request message and receiving a response message. The estimated delay time is compared with a predefined threshold value. If the estimated delay time exceeds the defined threshold value, an error signal is generated.

Abstract: In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. At least one data field to be filled with transmission data is clearly assigned to each further station. The data frame is transmitted as an outgoing data frame from one station to the next, with every further station filling the respectively assigned data field with transmission data. The last station returns the data frame as a returning data frame to the series of stations. The stations read extraneous transmission data from the data fields in the returning data frame. Preferably, the respective data fields are individually assigned to the stations.
