Abstract: A method for parametering a field device of automation technology by means of a service device. The field device includes at least a battery, a radio module and a non-volatile memory. The battery supplies the radio module and the non-volatile memory, in which parameters of the field device are stored, with energy. The method comprises the steps of: establishing a wireless connection between the servicing device and the battery operated radio module of the field device, wherein the field device is operated offline; reading and/or writing parameters of the field device stored in the non-volatile memory; terminating the wireless connection between the servicing device and the battery operated radio module of the field device; connecting the field device to a two-wire line for energy supply of the field device; and parametering the field device after connecting to the two-wire line, wherein, for parametering, at least parameters stored in the non-volatile memory are accessed.

Abstract: A synchronous rectifier, which rectifies an alternating voltage signal as an input signal and/or forwards a dc voltage signal as an input signal for use as an output signal. Included is a rectifying unit composed of at least one controllable switch element; a smoothing unit, which is connected to the rectifying unit and smooths the signal rectified or forwarded by the rectifying unit, in order to provide a smoothed signal for use as output signal; a control logic, which controls the rectifying unit based on the input signal and the output signal coming from the smoothing unit.
