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 network communication, you have several
communication modules from which to choose.
EtherNet/IP Communication Modules
Functions
• Control I/O modules.
• Require an adapter for distributed I/O on EtherNet/IP links.
• Communicate with other EtherNet/IP devices (messages).
• Share data with other Logix5000 controllers (produce/consume).
• Bridge EtherNet/IP links to route messages to devices on other
networks.
• Require remote access via Internet browser to tags in a local
ControlLogix controller.
• Communicate with other EtherNet/IP devices (messages).
• BridgesEtherNet/IP links to route messages to devices on other
networks.
• Does not support I/O or produced/consumed tags.
