Abstract
A method is disclosed for safe communication between a communication system by way of an OFDM method between a master and a slave, the master being able to communicate via a management channel and via a payload data channel with the slave. In an embodiment, the master assigns frequency spectra to be used for the payload data channel. The master is allocated an address of the slave and the master subsequently allocates the address to one of the frequency spectra to be used for the payload data channel. The slave stores the address transferred to it in its first microcontroller and the slave stores the address received via the payload data channel in the second microcontroller. The slave then checks whether the stored addresses match.
