Abstract

Disclosed is a field device adapter for HART communication with a field device. The field device adapter includes an adapter housing with an adapter chamber; arranged in the adapter chamber, an adapter electronics, which is adapted wirelessly to receive a second radio signal and by means of the second radio signal to control a circuit for shunting the communication resistor in such a manner that at least one communication resistor is selectively switchable in and out per radio, so that in a shunted condition a first radio signal received by the adapter electronics can be converted into a, preferably HART based, two conductor signal and modulated via the tapping point onto the loop current.
