Change the EtherNet IP Mode

Some controllers, such as cpl> 5380 and
CompactLogix
 5480, support one or more configurable Ethernet port pairs. Configurable Ethernet ports allow pairs of physical Ethernet ports to be configured in either a Linear/DLR or Dual-IP mode.
When configured for Linear/DLR mode, both ports of the configurable pair reside on the same Ethernet network (linear or ring topology) and share IP settings.
L5K_Linear_DLR_mode
When configured for Dual-IP mode, both ports of the configurable pair reside on separate Ethernet networks, each with its own IP address.
L5K_dual_IP_mode_5480
The operation mode of the Ethernet ports can be changed using the
Change EtherNet/IP Mode
 dialog box.
TIP:
The
CompactLogix
 5480 controller's standalone B1 port is not reconfigurable and retains the same configuration regardless of the EtherNet/IP Mode.
Before you begin:
  • Take the software program offline.
To change the EtherNet/IP mode:
    1. On the
      Online
      toolbar, click the
      Controller Properties
       icon.
    2. On the
      Controller Properties
      dialog box, click the
      General
       tab.
  2. Select
    Change IP Mode
    .
  3. In the
    New mode
     box, select the new EtherNet/IP Mode.
    • A1/A2: Dual-IP
       - a pair of physical Ethernet ports are configured as separate CIP EtherNet/IP ports
    • A1/A2: Linear/DLR
       - a pair of physical Ethernet ports are configured as a single CIP EtherNet/IP port supporting linear and ring topologies
  4. If changing from Linear/DLR to Dual-IP and an I/O module is underneath one of the configurable Ethernet port pairs in the I/O Configuration tree, in
    Move I/O and MSG Path to port
     box, select the local Ethernet port to add the I/O module.
  5. Select
    OK
    .
