Chapter 4 Communicate over Networks
EtherNet/IP Network
Communication
The EtherNet/IP network offers a full suite of control, configuration and data
collection services by layering the Common Industrial Protocol (CIP) over the
standard Internet protocols, such as TCP/IP and UDP. This combination of
well-accepted standards provides the capability required to both support
information data exchange and control applications.
The EtherNet/IP network also uses commercial, off-the-shelf Ethernet
components and physical media, providing you with a cost-effective plant-floor
solution.
For EtherNet/IP communication, you can use these CompactLogix controllers
with a built-in EtherNet/IP communication port:
• 1769-L32E CompactLogix controller
• 1769-L35E CompactLogix controller
You can use several software products with a 1769 CompactLogix controller on
an EtherNet/IP network.
The EtherNet/IP communication modules:
• support messaging, produced/consumed tags, HMI, and distributed I/O.
• encapsulate messages within standard TCP/UDP/IP protocol.
• share a common application layer with ControlNet and DeviceNet.
• interface via RJ45, category 5, unshielded, twisted-pair cable.
• support half/full-duplex 10 Mbps or 100 Mbps operation.
• support standard switches.
• require no network scheduling.
• require no routing tables.
In this example:
• the controllers produce and consume tags amongst themselves.
• the controllers initiate MSG instructions that send and receive data or
configure devices.
• the personal computer uploads or downloads projects to the controllers.
• the personal computer configures devices on an EtherNet/IP network.
