The DLR protocol provides high network availability in a ring topology and wasintended primarily for implementation in EtherNet/IP end-devices that have two Ethernetports and embedded switch technology, providing fast network fault detection andreconfiguration to support the most demanding control applications.1.3 Features1.3.1 Delta EIP ArchitectureThis typical Delta EIP architecture includes EIP Scanner and Adapter; data mapping can be achieved between devices viaan I/O connection and explicit message. The AHCPU5X1-EN series which includes AHCPU501-EN, AHCPU511-EN, AHCPU521-EN and AHCPU531-ENsupport Ethernet single port communication and for network installation, it is required to employ EtherNet/IPdevices. The AHCPU560-EN2, AH10EN-5A and AHRTU-ETHN-5A series support Ethernet dual port and DLR function; thusit can install, configure, and maintain linear as well as device-level ring (DLR) networks by using EtherNet/IPdevices with embedded switch technology.
