Abstract:
1. An apparatus for determining and/or monitoring at least one process variable, comprising: at least one, first electronics unit; at least one, second electronics unit; and at least one transferring unit, wherein: said at least one transferring unit is arranged between said at least one first electronics unit and said at least one second electronics unit; said at least one transferring unit is embodied in such a manner, that it transmits electrical energy and data between said at least one first electronics unit and said at least one second electronics unit; said at least one transferring unit is embodied in such a manner, that it transmits data from said at least one first electronics unit to said at least one second electronics unit by controlling frequency of transmission of the electrical energy; and said at least one transferring unit is embodied in such a manner, that, for transmitting a logical zero from said at least one first electronics unit to said at least one second electronics unit, said at least one transferring unit interrupts transmission of electrical enemy for predeterminable time period and/or sets the electrical energy for a predeterminable time period.
