Abstract: A method for operating an electronic consumption data module. Consumption data are transmitted via a communication system to a receiver, and different keys are provided for different software authorizations. Command authorizations are defined as software authorizations in the consumption data module. A consumption data module has a memory, a control and/or regulating unit, and a communication device for the consumption data transmission. Different keys are provided for different software authorizations, and the command authorizations are defined as software authorizations in the consumption data module. The consumption data module is operable by the method.

Abstract: Communication between a terminal, such as a consumption meter, installed at a fixed location and a mobile data collector, by way of Wireless M-Bus, via a short-range radio receiver. Data from the terminal is forwarded to the data collector via a bidirectional WPAN interface. The terminal sends a message periodically and unprompted for the communication set-up and subsequently opens a reception window after a period of time. In response, a command or a command sequence is conveyed from the mobile data collector to the receiver and to the terminal in one or more reception windows. The receiver determines the reception time at which the message arrives at the receiver, and the receiver stipulates the time at which the command or command sequence is transmitted onward to the terminal, so that the command or command sequence is received by the terminal within one reception window or multiple reception windows.

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.
