ABSTRACT:
To permit ready change of information on information carriers applied to workpieces which travel along a production line, for example to control further operating, machining or assembly steps, non-contacting sensors, typically inductive elements generating an electromagnetic field, transfer to a pick-up coil on the information carrier binary data. The information carrier includes a non-volatile permanent memory (ROM 25, 41) containing data characterizing the particular workpiece carrier or workpiece thereon, and a re-programmable, preferably non-volatile memory (RAM 27, 42) which contains added at the various operating stations to characterize operations, dimensions and the like of the respective workpiece and/or subsequent operations to be performed. The non-contacting transformer formed by the write/read stations and the pick-up coil (33, 47, 50) may, simultaneously, function as an energy transfer element to transfer operating energy for the memory units (23, 24, 40) on the workpiece carriers (11, 12) or the workpieces themselves (14, 15).
