Support for all common technical tools for S7
NETLink® WLAN, PROFIBUS Ethernet WLAN gateway
The NETLink® WLAN is an Ethernet Gateway with integrated WLAN function. As an alternative to the RJ45 socket, the required “Ad-hoc” or “Infrastructure” mode can be parameterized using the web interface. There is support for all standard wireless security methods, such as WEP, WPA, and WPA2. The NETLink® WLAN obtains its supply voltage from the CPU of the automation device or optionally from externally supplied DC 24 V.
