NETLink® WLAN, PROFIBUS Ethernet WLAN gateway
In general, connection to each MPI/PROFIBUS terminal of the bus system or directly at the interfaces of active and passive participants is also possible. The PG socket integrated in the connector housing allows connection of additional devices.
The integrated web interface offers parameterization, diagnostic, and security features, and for functional enhancements, the user can use our free diagnostic software SHTools to, for example, automatically perform firmware updates. The latest version is available for download.
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. All of the following standard wireless security methods are supported: WEP, WPA, and WPA2. The NETLink® WLAN obtains its supply voltage through the CPU of the automation device or optionally from externally supplied DC 24 V.
The NETLink® WLAN enables implementation of TCP/IP on the MPI/PPI/PROFIBUS with up to 32 simultaneously open connection channels. With the switchable single-master operation, passive bus participants can be addressed. The integration of SCADA, HMI, and OPC applications is possible via the widely used ISO on TCP (RFC 1006) protocol. They are automatically recognized and forwarded by NETLink® WLAN.
