EtherNet/IP Overview
EtherNet/IP networks are communication networks that offer a comprehensive
suite of messages and services for many automation applications.
These are examples of applications that use EtherNet/IP networks:
• Real Time Control
• Time Synchronization
• Motion
This open network standard uses off-the-shelf Ethernet communication products
to support real-time I/O messaging, information exchange, and general
messaging.
EtherNet/IP networks also support CIP Safety, making the simultaneous
transmission of safety and standard control data and diagnostics information over
a common network possible.
EtherNet/IP Communication
Modules in a Control System Depending on the type, Rockwell Automation EtherNet/IP communication
modules provide some of this functionality:
• Support for messaging, produced/consumed tags, and distributed I/O
• Encapsulate messages within standard TCP/UDP/IP protocol
• Share a common application layer with ControlNet and DeviceNet
network protocols
• Interface via RJ45, category 5, unshielded, twisted-pair cable connectors
• Fiber connectors
• Support for half/full duplex 10 Mbps or 100 Mbps operation
• No network scheduling or routing table requirements
