9.1.2 Definitions of Common Network Terms
Term Definition
ODVA Open DeviceNet Vendor Association for EtherNet/IP
EIP
EtherNet/IP, an industrial Ethernet network, provides interoperability for system providers.
IP stands for Industrial Protocol. The term “EIP” (EtherNet/IP) is used in this manual.
I/O Connection Use the I/O connection to connect to EtherNet/IP and to exchange data cyclically.
Explicit Message
Connect to EtherNet/IP and to exchange data non-cyclically. Data is exchanged piece by
piece through instructions.
RPI
Requested Packet Interval, through the I/O connection to connect to EtherNet/IP to
exchange data at regular time intervals.
ACD Address Conflict Detection to detect IP address duplications.
Produced/Consumed
TAG (P/C TAG)
 You use TAGs for assigning and referencing memory locations for Rockwell PLCs,
the same as registers for Delta PLCs.
 Produced tag: A tag that a controller makes available for other controllers. Multiple
controllers can simultaneously consume (receive) the data. A produced tag sends
its data to consumed tags (consumers) without using logic.
 Consumed tag: A tag that receives the data of a produced tag. The data type of the
consumed tag and the produced tag must match (including any array dimensions).
 The data is transferred over Ethernet/IP. For example, PLC-A needs data from
PLC-B, so PLC-B sends the data to PLC-A. Therefore, PLC-B is the producer and
PLC-A is the consumer.
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.
