Abstract: A central controller for a data network includes an input interface for receiving a request signal, a control unit for generating a control signal depending on the request signal received, and at least one output interface for transmitting the control signal to at least one participant device. The control signal is set up to actuate the at least one participant device to emit a participant output signal for identifying a physical position of the at least one participant device.

Abstract: Provided is a method for operating a measurement system including an evaluation module and several measuring elements. The evaluation module and the measuring elements are connected via a communication line. The method includes detecting measurement data via the several measuring elements. At least two of the measuring elements detect the measurement data at least partially at the same time. The method further includes: buffering the detected measurement data in the respective measuring element; and reading out the measurement data buffered in the measuring elements with the evaluation module via the communication line.
