The method is used for transmitting signals and data within at least one first and one second transmission phase (TP, TP), which follow one another synchronously or asynchronously, between a first communication unit (L) and at least one second communication unit (Z), which comprises a central processor unit (CPU), a memory unit (M), in which an operating program (OP) is stored, and at least one first event generator (EG), which monitors signal sequences (SL, SZ) transmitted via a transmission line (W) between the two communication units (L, Z) independently of the central processor unit (CPU) and generates event notifications (e, e) for events during the data transmission, which occur in accordance with the applied transmission protocol, which event notifications are transmitted to the central processor unit (CPU) and/or to at least one event user (EU).

Method and device for data transmission and counter unit

A meter includes a hermetically encapsulated electronic metering mechanism having a meter unit for the determination of meter readings, the metering mechanism including a data memory for storing the meter readings, and the metering unit including an antenna of a defined shape, and a readout unit arranged outside the metering mechanism for reading the meter readings from the data memory. The meter is operated according to a method for the determination of meter readings and for the wireless transmission of electrical energy. The shape of the readout unit antenna is identical to the shape of the metering unit antenna, wherein the congruent and predefined positioning of the readout unit antenna ensures an effective wireless energy supply to the metering unit by electromagnetic radiation through the readout unit, and, independently thereof, a stable wireless data coupling for the determination of meter readings between the metering unit and the readout unit.
