EEtthheerrNNeett//IIPP NNeettwwoorrkk
The Ethernet Industrial (EtherNet/IP) network protocol is an open industrial networking
standard that supports both real-time I/O messaging and message exchange. It emerged
due to the high demand for using the Ethernet network for control applications. The
EtherNet/IP network uses off-the-shelf Ethernet communication chips and physical media.
The EtherNet/IP network provides excellent drive and I/O control performance along with
HMI information processing and many commercial technologies.

Select the appropriate controller and EtherNet/IP interface depending on the application
and how the controller interacts with the devices:

• Controls I/O modules
• Requires an adapter for
distributed I/O on EtherNet/IP
links
• Communicates with other
EtherNet/IP devices (messages)
• Bridges EtherNet/IP links to
route messages to devices on
other networks
1768-ENBT
The 1768-ENBT module:
• controls I/O over an EtherNet/IP network.
• routes messages to devices on other networks.
• sends real-time, connected, peer-to-peer data between multiple
controllers.
• sends and receives email.
• Sends and receives messages
over the EtherNet/IP network
• Transfers small amounts of
data over the EtherNet/IP
network
1761-NET-ENI interface, series B
The 1761-NET-ENI series B interface module routes a DF1 message
received from the attached controller to a compatible destination
TCP/IP device. This is accomplished by using DF1 node addresses 0
to 49. The 1761-NET-ENI node addresses 100 to 149 store TCP/IP
destination addresses. When the 1761-NET-ENI receives a write
message to nodes 100 to 149, it stores the TCP/IP destination
address in the corresponding map register.

The 1768-L43 controller supports a maximum of two 1768 modules.
7The 1761-NET-ENI is an Ethernet to serial linking device. While 10 MB is the fastest communication rate supported by a 1761-NET-ENI device, the actual network performance depends on the maximum serial port connection
speed.
