Chapter 9 Ethernet Specification and Operation

EDS
Electronic Data Sheets: EDS files are simple text files used by EtherNet/IP network
configuration tools to help you identify EtherNet/IP products and easily commission them
on a network.
Data Mapping Exchanging data between devices
EIP Scanner The master station is called an EIP Scanner in EtherNet/IP.
EIP Adapter The slave station is called an EIP Adapter in EtherNet/IP.
DLR
Device Level Ring (DLR) provides fault-tolerant network design for daisy-chain and linear
topology. The DLR protocol provides high network availability in a ring topology. It was
intended primarily for implementation in EtherNet/IP end-devices that have two Ethernet
ports and embedded switch technology, providing fast network fault detection and
reconfiguration to support the most demanding control applications.
Modbus TCP This is a Modbus variant used for communications over TCP/IP networks.
9.1.3 Ethernet Features
9.1.3.1 Delta EIP Architecture
This typical Delta EIP architecture includes an EIP Scanner and Adapters; data mapping is achieved between devices
through an I/O connection and explicit messaging. The AS Series supports single port Ethernet; thus you can install and
configure devices with embedded switch technology over EtherNet/IP.
