Abstract: A system includes a number of frequency converters, wherein a respective frequency converter has a wired data interface and a frequency converter parameter memory. The system further includes a number of wireless local area network modules, wherein a respective WLAN module has a wired data interface. The data interface of the WLAN module can be coupled to the data interface of a frequency converter for the purpose of bidirectional data exchange, wherein the frequency converter parameter memory of a frequency converter is designed to store values of a number of frequency converter WLAN parameters.

Abstract: A field bus system (16), especially a LIN bus system, has a master (14) and at least one bus subscriber (15). In order to carry out an automatic configuration of the bus system, the master (14) stores the current configuration of the field bus system (16) as the known configuration, and carries out the following steps after restarting the bus system: a standard address is allocated as a subscriber address to the at least one bus subscriber (15); it is checked whether the at least one bus subscriber (15) belongs to the known configuration and, if this is the case, a unique subscriber address is allocated thereto (15); it is then checked whether the at least one bus subscriber (15) still has the standard address and, if this is the case, the at least one bus subscriber is identified and a unique subscriber address is allocated thereto.
