Abstract: A bus coupler for a network, in particular for an optical ring network, includes: a bus participant interface for data connection to at least one bus participant device; a bus receiving interface for receiving bus input data via a bus line; a bus transmitting interface for transmitting bus output data via the bus line; and a control unit for generating bus output data based on participant input data received via the bus participant interface, the bus transmission data including bus control data, and to transfer the bus output data to a further bus coupler by the bus transmitting interface. The control unit specifies a control signal based on the bus input data received by the bus receiving interface and performs a relaying of the bus input data to the further bus coupler based on the specified control signal.

Abstract: An I/O system component for a switch and control cabinet for components and/or functional units of an I/O network, including: a housing with a front, a top, a bottom, at least one side face, and a sensor window; at least one ultrasonic sensor for detecting at least one physical quantity, the at least one ultrasonic sensor being arranged behind the sensor window; and at least one printed circuit board, the at least one ultrasonic sensor being connected to the printed circuit board so as to carry data.
