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.
