Ethernet Features

9.1.4.1 Delta EIP Architecture
This typical Delta EIP architecture includes an EIP Scanner and Adapters; data exchange 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.
PLC-B, so PLC-B sends the data to PLC-A. Therefore, PLC-B is the producer and
PLC-A is the consumer.
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.
Exchanging data between devices
The master station is called an EIP Scanner in EtherNet/IP.
The slave station is called an EIP Adapter in EtherNet/IP.
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.
This is a Modbus variant used for communications over TCP/IP networks.
