In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. The time tracking tool may perform operations related to tracking time based on activity of a computer operating the time tracking tool relative to status of the time tracking tool. In order to derive control statements, at least two surface points each from the point cloud are used for every horizontal position so that non-differentiated information can be derived that for example also allow to identify various planes.
