2.1 EtherNet/IP Device
A Delta EtherNet/IP (EIP) device allows users to build a linear topology, ring topology, and star topology. A
Delta EIP device includes the EIP Builder software, EIP Scanner, EIP Adapter, EIP Tap, and Ethernet switch.
EIP Scanner and EIP Adapter, each of them can be further divided to a single port and dual port.
Ethernet single port: the AHCPU5X1-EN series including AHCPU501-EN, AHCPU511-EN,
AHCPU521-EN and AHCPU531-EN.
Ethernet dual port: the AHCPU560-EN2, AH10EN-5A and AHRTU-ETHN-5A series
2.2 Network Installation
Each EtherNet/IP device is connected to an Ethernet switch via a CAT 5e cable. Please use Delta standard
cables and the DVS series industrial switches. Refer to Delta PLC/HMI Cable Selection Guide for more
information.
2.2.1 Single Port Device
A single port device can build up a linear and a star topology. An Ethernet switch is required to create a star
topology and a ring topology, and additionally an EtherNet/IP Tap is also needed.
