Abstract
The invention relates to a measuring arrangement having a two-wire field device comprising a control unit, a sensor, and a radio module, a superordinate unit to which the field device is connected via a two-wire line, wherein signals from the field device are transmitted to the superordinate unit at least as a current injected by the field device in a predetermined range to the superordinate unit, wherein an error current below the predetermined range signals an error, and a maintenance current above the predetermined range signals a maintenance mode, and the field device is designed in such a manner that the maintenance current feeds the radio module in the radio operation.
