1. A method for safe communication within a communication system with a master, a communication bus and a slave, the slave including a first and a second microcontroller, wherein the slave is connected via the communication bus to the master, wherein communication between the master and the slave is configured to occur via a management channel and via a payload data channel, wherein the communication from master to slave is undertaken by way of an OFDM method, and wherein, during communication via the management channel, a different frequency spectrum is used than is used for communication via the payload data channel, the method comprising:
assigning, via the master to the slave via the management channel frequency, spectra to be used for the payload data channel; allocating the master an address of the slave; subsequently allocating, via the master to the slave, the allocated address one of the frequency spectra to be used for the payload data channel between the slave and the master; transferring, via the master to the slave, the address allocated to the slave via the management channel, the address transferred to the slave being subsequently stored in a first microcontroller; transferring, via the master, the address of the slave via the frequency spectrum allocated to the address of the slave, the address subsequently being received via the payload data channel and stored in the second microcontroller, and the slave subsequently checking whether the address stored in the first microcontroller matches the address stored in the second microcontroller. |
