Abstract
The invention relates to a positioner () for an actuator () comprising a processing unit () and an output unit () which can be connected to an actuating drive () of an actuator (), as well as a measurement unit (). The invention is characterized in that said positioner () comprises a current source () which can be connected to a voltage source () of a control system () via a single two-wire current loop (). The invention furthermore relates to a method for operating a positioner () including the transmission of measuring values recorded in the positioner () to a higher-level controller (). The method is characterized in that the actuating signals are transmitted in a digital form whereas the measuring data is transmitted to a higher-level controller in an analog form, with both digital and analog signals being transmitted on the same two-wire line.
