Abstract
The method and apparatus for transmitting data are used in a manufacturing machine, particularly a yarn manufacturing machine containing a plurality of production stations, a plurality of associated monitoring locations, a plurality of respective monitoring sensors, and a central control unit. The central control unit applies to the monitoring locations a modulated supply voltage via a conductor common to all of the monitoring locations. The modulated supply voltage contains a plurality of sections each of which is associated with one of the plurality of monitoring locations. The associated section is identified at the monitoring location by counting from a starting point which is marked in the modulated supply voltage. At the occurrence of a predetermined event at respective ones of the plurality of monitoring locations, respective sections of the modulated supply voltage are marked. The marked sections as well as the respective monitoring locations are identified in the central control unit.
