EtherNet/IP Network

The controller operates on
EtherNet/IP™
 networks. Before your controller can operate on an
EtherNet/IP™
 network, you must first configure the driver in
FactoryTalk® Linx
 software. For information on how to configure
EtherNet/IP™
 or USB drivers, see the EtherNet/IP Network Devices User Manual, publication ENET-UM006.
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 that is required to support information data exchange and control applications.
The controllers use socket interface transactions and conventional communication over the
EtherNet/IP™
 network to communicate with Ethernet devices that do not support the
EtherNet/IP™
 application protocol.
IMPORTANT: With
ControlLogix®
 5590 controllers, the Ethernet ports on the controller itself are labeled 1 and 2. In programming and communication software, the ports are described as A1 and A2.

EtherNet/IP Network Functionality

The controllers support the following:
  • Dual built-in
    EtherNet/IP™
     network ports - Port 1 and Port 2
  • Support for these
    EtherNet/IP™
     modes:
    • Dual-IP mode (Default)
    • Linear/DLR mode
  • Support for these
    EtherNet/IP™
     network topologies:
    • Device Level Ring (DLR)
    • Linear
    • Star
  • Support for these
    EtherNet/IP™
     network communication rates:
    • 10 Mbps
    • 100 Mbps
    • 1 Gbps
  • Support for only full-duplex operation
  • Support for
    CIP Sync™
     technology that is based on Time Synchronization using the IEEE-1588 Precision Time Protocol
  • Duplicate IP address detection
ATTENTION: 10 Mbps Ethernet automatic negotiations are functional, however, they are not fully supported or intended for normal use. Use 10 Mbps Ethernet connections, only if necessary, during temporary setup.
For more information about network design, see the Ethernet Design Considerations Reference Manual, publication ENET-RM002.
