Abstract: The method is provided for addressing the participants of a bus system comprising a control unit, a bus starting from the control unit and a plurality of participants connected to the bus. In the method, each participant not addressed so far feeds an identifying current for identification purposes into the bus, wherein all identifying currents flow through the bus towards the control unit. Each participant not addressed so far detects the current flowing through the bus. Only that participant not addressed so far, which does not detect any current or merely detects a current which is smaller than a predeterminable first threshold value, is identified as a participant not addressed so far. An address for addressing purposes is assigned to the participant thus identified. The aforementioned steps are carried out, without the respective participant addressed last, until all participants not addressed so far are addressed.

Abstract: A method and a device for controlling a stepping motor in which the width of step and the direction of rotation of the stepping motor are determined in a controller and sent to a control arrangement for controlling the stepping motor. Upon each step clock signal from the controller, a step is carried out. The step width output by the controller is divided by the control circuit into a plurality of smaller partial steps the step width of which is smaller than the step width output by the controller, and these partial steps are sent in several time-staggered pulses by the control circuit to the stepping motor.

Abstract: A process for reducing the strength of an uncontrolled movement of a pointer driven by a stepper motor and abutting against a mechanical stop means when the stepper motor is switched off. Prior to the switch-off operation, the field strength of the magnetic field of the stepper motor is lowered, or the pointer is moved away from the stop means by a specified compensating angle of rotation. Alternatively, following the switch-off operation, the stepper motor is switched on again at least one time following a specified time span for a specified switch-on time span.
