发明名称 Control electronics for a process device and method for operation therefor
摘要 Control electronics (E) for a two-wire process device, which two-wire process device can be connected to a two-wire loop (2L), wherein the control electronics (E) comprises an input circuit (ES) and a control unit connected to the input circuit (ES), wherein the input circuit (ES) is used in a first operating mode to set a current and/or voltage in the two-wire loop (2L) by means of a control signal (CS) transmitted by the control unit (SE), wherein the input circuit (ES) is used in a second operating mode to automatically, in particular independently of the control unit (SE) or independently of the control signal (CS) transmitted by the control unit (SE), to set the current and/or the electric voltage in the two-wire loop (2L).

主权项 1. Control electronics (E) for a two-wire process device, which two-wire process device can be connected to a two-wire loop (2L), wherein the control electronics (E) comprise an input circuit (ES) and a control unit connected to said input circuit (ES), wherein the input circuit (ES) is used, in a first operating mode, to set a current and/or a voltage in the two-wire loop (2L) by means of a control signal (CS) transmitted by the control unit (SE), wherein the input circuit (ES) is used, in a second operating mode, to set the current and/or the electric voltage in the two-wire loop (2L) automatically, in particular independently of the control unit (SE) or independently of the control signal (CS) transmitted by the control unit (SE).
