A method for operating a fieldbus protocol capable field device, wherein the fieldbus protocol includes at least one command, which serves, depending on a value of an auxiliary variable, for performing a first function, respectively for performing a second function, of field device, wherein the first and second functions differ from one another.

Method for operating a fieldbus protocol capable field device

An apparatus for issuance of at least one electrical output signal (Iout), wherein the desired electrical current level of the output signal (Iout) is predeterminable, including: at least one measuring resistor, at which the electrical current level of the output signal (Iout) is measurable; at least one adjuster, via which the electrical current level of the output signal (Iout) is settable; and at least one controller, which compares the electrical current level of the output signal (Iout) measured at the measuring resistor with the electrical current level desired for the output signal (Iout), and which controls the electrical current level of the output signal (Iout) via the adjuster; wherein the controller and the measuring resistor are connected with an electric base-potential (VGND); and wherein the base-potential (VGND) is a reference potential for the controller.
