Described is a method for data communication in a communication system. The system includes a plurality of communication participants, each participant having a subsystem responsible for communication. A communication participant acts as master of the communication system, the subsystem of the master being operated continuously. The other communication participants act as communication slaves in the communication system. The subsystems of the communication slaves are de-energized, when no communication takes place. Furthermore, a protocol for controlling a bidirectional communication is provided. Establishment of the communication results from a special initial packet, which is transmitted by a communication slave to a communication master. The initial packet is acknowledged by the master with a confirmation packet. This confirmation packet comprises information, whether subsequent communication is required. Moreover, a communication system is provided, comprising a plurality of communication participants each having a respective subsystem responsible for the communication. At least one communication participant is adapted to act as master in the communication system, having a continuously operating subsystem. The other communication participants are adapted to act as communication slaves in the communication system, having subsystems, which are de-energized, when no communication takes place, whereby the communication participants are sensors.
