Local Wireless Access To Rmc By Host - ABB XIO-08 User Manual

–
When there are several XIOs, one may be configured as an access point and the others as clients. In
this scenario, the Wi-Fi client only joins a single wireless network, but can establish connection to all
XIOs on that network.

Local wireless access to RMC by host

The XIO AP bridge mode supports bridging of network traffic from a local wireless client to a wired device.
Figure 11-3 depicts this scenario. The host with PCCU has Wi-Fi client capabilities and can establish a
wireless link to the local wireless network advertised by the XIO. The XIO is configured in AP-Bridged
mode. It connects to the wired network (using A1 port). When it receives traffic directed to the RMC IP
address, on its wireless link, it forwards that traffic to the A1 port. The RMC receives traffic on its Ethernet
port (E2). This network traffic flow is depicted by the blue line.
IMPORTANT NOTE: The XIO supports the Wi-Fi AP bridged mode only when in 4-port switch
mode.
