Enable DHCP on the laptop for automatic addressing. First-time direct connection between the XIO and
the laptop does not require any configuration of IP parameters in either system, (if DHCP is enabled on
the laptop.)

9.4 Network communication on 4-port switch mode
The XIO controller must be configured for network communication as its core functionality depends on
TCP/IP-based connections with remote controllers.
Successful network communication depends on correct configuration of valid IP parameters for all devices
on a field network. Configuration depends on desired network topologies. The XIO supports several
scenarios with its different modes of operation as described in section 9.1.2 Ethernet modes
.
Factory default IP configuration is meant for initial local access only. Valid IP configuration for the chosen
topology must replace factory defaults. Each XIO on the field must have unique IP addresses.
Local access to the XIO and other devices on the network is still supported after the default configuration
is replaced, but the operator laptop must have an IP configuration compatible with the non-default
addresses assigned to the XIOs. Local access is also available using Wi-Fi
®
as described in 10 Wi-Fi®
connectivity scenarios.
Network communication supports:
— Host system-to-device access (local and remote): PCCU clients can connect to XIOs for
configuration or management purposes from the corporate network or on the field.
— Device-to-device communication (local): Remote controller-XIO communication is supported when
devices connect to a field network switch on independent connections (star topology) or when
devices connect to each other in daisy-chain fashion.
9.4.1 Daisy-chain connection support by the RMC
When the XIOs are deployed for connection to an RMC-100 in the field, they can connect to a field
network switch or an RMC for the uplink connection to the corporate customer network (WAN). The RMC-
100 supports this connection with its two Ethernet ports. These ports can be configured as: Switched
