Abstract: An inductive sensor (10) has a substrate (20), on which multiple transmitter/receiver coils (31, 32, 33) are arranged side by side. It can be operated in such a way that the transmitter/receiver coils (31, 32, 33) are each stimulated independently of one another at a frequency of more than 100 MHz.

Abstract: A wireless IO-link communication network has a main master and at least one device which have a bidirectional wireless communication between the main master and the at least one device, as well as a backup master which is connected to the main master and the at least one device and is configured to control the at least one device. In a method for operating the IOLW communication network with such a backup master, the backup master controls the at least one device instead of the main master.

Abstract: A fixing element for electrical devices, wherein at least one electrical device can be fixed to the fixing element, has at least one coupler, which forms at least one coupling to the at least one electrical device fixed to the fixing element, via which coupling electrical energy and/or data can be transmitted to the at least one electrical device, wherein the coupling is a capacitive and/or inductive coupling. In addition, equipment includes such a fixing element and a least one electrical device, which is fixed to the electrical element.

Abstract: An interface (10) for an IO-Link master (20) has an IO-Link port transceiver, at least one wireless transceiver and a signal processing apparatus which is configured to provide a network between the IO-Link port transceiver and the at least one wireless transceiver. In a method for controlling an IO-Link system, a communication partner (30) communicates with at least one IO-Link device (40) via an interface (10). In a method for monitoring the IO-Link system, a communication flow between IO-Link ports (21, 22) of the IO-Link master (20) is stored in a storage element by means of the interface which is connected to the IO-Link master (20). The IO-Link master (20) has at least one IO-Link port (21) which is configured to be connected with an IO-Link port transceiver of the interfaces (10).
