Abstract

The invention relates to a method for energy management of a process automation field device having a first module and at least a second module, wherein the field device is supplied with energy by a two conductor bus, wherein the first module, at least temporarily, consumes more energy than the two conductor bus continuously delivers, and an energy storer supplied by the two conductor bus is associated with the first module, wherein the second module is supplied continuously with energy by the two conductor bus, wherein operation of the first and second modules is so controlled that the second module has precedence over the first module and the first module is, in given cases, at least temporarily, not functional.
