Abstract
A method for safely parameterizing an electrical device, wherein a parameter input by a user on a control unit is transmitted to the electrical device and stored therein with write protection, the stored parameter is transmitted back to the control unit and displayed at the control unit for confirmation by the user, and the user confirmation is transmitted to the electrical device. In accordance with the invention, the stored parameter is transmitted back together with the name of the parameter, with a code generated by the device and in a data format which cannot be processed by the control unit. The returned parameter, the name of the returned parameter and the code are displayed for the user on the control unit, and the confirmation is checked in the electrical device to determine whether the confirmation contains the code.
