Abstract:
A field device of process automation technology which includes a hardwire communication interface and a functional unit associated with the communication interface. The functional unit is embodied in such a manner, that it performs sending and/or receiving of digital signals via the communication interface. The field device is embodied in such a manner, that the functional unit is operable in a clocked manner, wherein, in the clocked operation, active time periods, in which the functional unit is activated, alternate with turned-off periods of time, in which the functional unit is switched off.
