Chapter 6 Connect to Different EtherNet/IP Network Levels
Connect to a
Device-level Network
The CompactLogix 5480 controller Ethernet ports A1, A2, and B1 can
connect to device-level networks. Remember the following when you connect
to device-level networks:
• You are not required to connect the controller to an enterprise-level
network to connect to device-level networks.
• You can connect any combination of ports A1, A2, or B1 to device-level
networks.
• When you set the IP address and subnet mask, you establish an IP
address range for the port. Make sure that the IP address ranges that are
established for each port on the controller do not overlap.
For more information on overlapping IP address ranges, see
page 134.
When you connect a port to a device-level network, you configure the
following parameters:
• IP address (Required)
• Subnet mask, also called the network mask (Required)
• Gateway address (Optional)
• Host name (Optional)
Ports A1 and A2
Ports A1 and A2 can connect to the same device-level network or separate
device-level networks. The EtherNet/IP mode determines if the ports are
connected to the same network or different ones.
• If the controller uses Dual-IP mode, ports A1 and A2 connect to
separate device-level networks, that is, different subnets. You must
configure the parameters that are listed earlier in this section for
each port.
• If the controller uses Linear/DLR mode, ports A1 and A2 connect to
the same device-level network. In the Logix Designer application
project, the ports are port A1/A2 and use one sets of the parameters that
are listed earlier in this section.
For more information on EtherNet/IP modes, see
page 131.
