9.1 Introduction
9.1.1 EtherNet/IP
EtherNet/IP (“IP” stands for “Industrial Protocol”) is an industrial Ethernet network managed by ODVA, Inc. (formerly Open
DeviceNet Vendors Association, Inc.), a global trade and standards development organization.
EtherNet/IP works on a TCP/UDP/IP based Ethernet network and uses the most widely deployed collections of Ethernet
standards to provide a broad range of applications in different industries that require high-speed and stability including
Factory Automation (FA), Building Automation (BA), Process Automation (PA) and many more.
Delta covers a full range of controller and drive products supported by EtherNet/IP, including Programmable Logic
Controllers (PLC), inverters, Human Machine Interfaces (HMI) and so on. Refer to Section 9.9 for a full product list that
support EtherNet/IP. In addition, you can also use EDS files to connect to other brands of EtherNet/IP devices. You can
run Delta EtherNet/IP software (EIP Builder) through the ISPSoft software V3.0 or later. Download the ISPSoft software at:

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.
