Intended use of WAN and LAN ports
The WAN port is a public network interface to the controller, typically connected
to the factory network with a public IP address provided by the network
administrator.
The LAN ports are intended for connecting network based process equipment to
the controller, for example industrial networks, cameras, and welding equipment.
LAN 2 can only be used as a private network to the IRC5 controller.
Isolated LAN 3 or LAN 3 as part of the private network
The default configuration is that LAN 3 is configured as an isolated network. This
allows several robot controller to be connected to the same network, see
on dedicated industrial network on page 23
.
Note
The isolated LAN 3 cannot be used to connect to any HMI device (RobotStudio,
Robot Web Services, or PC SDK client) since it does not support the protocol
needed for communication.

An alternative configuration is that LAN 3 is part of the private network. The ports
Service, LAN 1, LAN 2, and LAN 3 then belong to the same network and act just
as different ports on the same switch. This is configured by changing the system
parameter
