Linear/DLR Mode

When controllers operate in Linear/DLR mode, they can only connect to one network with one network configuration. The two physical ports allow the controller to connect to a linear or Device level Ring (DLR) network topology.
By default, the EtherNet/IP mode is automatically set to Dual-IP mode. You must change the EtherNet/IP Mode to use Linear/DLR mode. For more information on how to change the controller to Linear/DLR mode, see the following:
