Claim:
1. A method for data transmission between measuring apparatuses and a data processing device in a measured data recording system, which has a plurality of measuring apparatuses and at least one controller, the method comprising the steps of: assigning an unambiguous code to each of the plurality of measuring apparatuses; providing a measuring line between each measuring apparatus and the controller for sending analog measured signals by the measuring apparatuses to the controller via the measuring lines and exchanging digital messages, via the measuring lines, between the controller and the measuring apparatuses; connecting the data processing device to the controller via a terminal of the controller for receiving digital data packets at the controller from the data processing device and sending digital data packets to the data processing device; repeatedly executing exchange steps by the controller, wherein an exchange step comprises: starting each of the exchange steps after a predefined time lag; sending of a first digital data packet by the data processing device to the controller, wherein the first digital data packet contains the unambiguous code of one of a plurality of measuring apparatuses and a first digital message; extracting of the unambiguous code from the first digital data packet by the controller; and sending of the first digital message to the one of the plurality of measuring apparatuses by the controller after a completion of one of the exchange steps.
