Definition
EtherNet/IP is an industrial communication protocol that runs the Common Industrial Protocol (CIP) over standard Ethernet networking, enabling controllers, drives, and I/O devices to exchange data using familiar Ethernet infrastructure. It is widely used in North American automation, particularly Rockwell Automation / Allen-Bradley environments, alongside other Ethernet-based industrial protocols.
Key facts
- Runs the Common Industrial Protocol (CIP) over standard Ethernet hardware and networking.
- Widely associated with Rockwell Automation / Allen-Bradley control systems, though used more broadly as well.
- Distinct from EtherCAT's specific low-latency frame-processing mechanism: EtherNet/IP uses more conventional Ethernet communication patterns.
- Benefits from standard Ethernet infrastructure compatibility, simplifying network design and equipment reuse.
How does EtherNet/IP work in maintenance?
EtherNet/IP works by carrying the Common Industrial Protocol's messages over standard Ethernet networking, allowing controllers, drives, and I/O devices to exchange both real-time control data and general information using widely available, standard Ethernet infrastructure and switches.
What does EtherNet/IP require?
EtherNet/IP shares the same physical Ethernet infrastructure as PROFINET and EtherCAT but uses the Common Industrial Protocol as its application-layer standard, and is particularly associated with Rockwell Automation / Allen-Bradley equipment, while PROFINET is more associated with Siemens environments and EtherCAT is chosen specifically for very low-latency motion applications.
