Configuration
To configure for 3-network support:
10.6
Separate 4-network support
The 4 Ethernet interfaces on the XIO can support separate 4 separate networks: 2 networks by the
Enterprise Network ports (port A1 and port A2) and 2 networks by the Industrial Network ports (port B1
and port B2). Each of these ports can be configured independently of the other to provide additional
connection and topology options in the field.
IMPORTANT NOTE: Separate configuration options for these ports become available only when
the XIO 4-port switch mode is disabled.
Table 10-7
summarizes the configuration options for this scenario. In this scenario all 4 interfaces support
separate networks. Traffic in each network is isolated to that network. The XIO does not route traffic
between interfaces. This scenario supports complex applications with several XIOs and where there is
need to isolate XIOs in separate subnets or domains within in the field. Consult with ABB Technical
Support for more details.
