Abstract
A method operates a data recording system which has a central station, an intermediate station, and a terminal station. The central station and the intermediate station define a tertiary, two-way communication path and the central station and the intermediate station define a primary, two-way communication path via a radio link. A plurality of messages or message parts which have different validity time limits are generated in the central station on the basis of a command, the plurality of message parts which are valid for a limited time are transmitted from the central station to the intermediate station. The validity of the message parts is checked in the intermediate station, and, if a message part is still valid for transmission from the intermediate station to the terminal station, the message part concerned is transmitted within a message from the intermediate station to the terminal station.
