    摘要: A method and device are provided for marking electrical devices which can be arranged in a row on a support rail, with the aid of a laser head, wherein the support rail is pivotable about its longitudinal axis and the laser head is guided such that it can be moved at least along the longitudinal axis of the support rail. A number of marking instructions, each including a marking content and a position and an orientation of the surface to which the marking content is to be applied are specified. An image of at least a section of the support rail and of at least one electrical device are created from an image capture device and at least one of the positions at which one of the marking contents is to be applied is corrected based on an evaluation of the image. The marking instructions are grouped into marking levels in such a way that all marking instructions of one marking level can be applied by the laser head without a movement of the laser head or the support rail. The marking levels differ in terms of spatial coordinates and/or parameters for the laser head. A first one of the marking levels is selected, and the laser head is positioned and/or the support rail is pivoted according to the spatial coordinates of the selected marking level. Markings are applied according to the marking instructions of the selected marking level with the parameters for the laser head. A next one of the marking levels for marking is selected based on the movements of the laser head and the support rail which would be necessary to enables markings according to the next one of the marking levels to be applied.
