Ethernet/IP Protocol
Elevate your network with ethernet/IP expertise.
What is Ethernet/IP Protocol?
EtherNet/IP is a standard communication protocol widely used in industrial automation and Industrial Internet of Things (IIoT) applications. It is governed by the Institute of Electrical and Electronics Engineers (IEEE) under the 802.3 standards, incorporating the TCP/IP protocol suite.
The “IP” in EtherNet/IP stands for Industrial Protocol, which adapts the Common Industrial Protocol (CIP) for Ethernet use. CIP standards enable device profiles and services essential for real-time applications and controllers. EtherNet/IP leverages Ethernet’s existing capabilities and translates them into an object model used by CIP (Common Industrial Protocol), allowing it to transmit any I/O messages across the network. This adaptability simplifies the implementation of automation functions, regardless of the variety of devices manufacturers use.
Many manufacturers continue to operate with legacy equipment on the factory floor, including machines, programmable logic controllers (PLCs), nodes, and other devices. These older Ethernet infrastructures and network topologies must be compatible with the data demands and traffic generated by modern machine data platforms. EtherNet/IP facilitates the integration of these platforms within a company’s existing network topology and infrastructure.
Advantages of Using EtherNet/IP in industrial applications
EtherNet/IP is a versatile and cost-effective protocol that empowers manufacturers to build interconnected, data-driven industrial automation systems. Below you will find a few advantages of using it.
Open and Accessible
EtherNet/IP is an open-source protocol, fostering widespread adoption and a diverse ecosystem of compatible devices from various vendors. This openness empowers manufacturers with greater flexibility and choice.
Universal Compatibility
A widely recognized standard, EtherNet/IP bridges the gap between legacy and modern systems, enabling seamless integration of equipment from different manufacturers. This eliminates the need for proprietary solutions, reducing costs and vendor lock-in.
Data-Driven Insights
EtherNet/IP facilitates easy access to machine data, providing valuable insights for optimizing operations, predictive maintenance, and informed decision-making.
Simplified Communication
By combining the strengths of Ethernet and CIP (Common Industrial Protocol), EtherNet/IP streamlines device communication, eliminating the need for extra hardware like routers and switches. This allows for efficient control, configuration, and data exchange across the entire enterprise network.
Flexible Deployment
EtherNet/IP accommodates a variety of network topologies, including existing Ethernet setups (star, ring, daisy chain) and the integration of wireless devices, offering manufacturers the freedom to tailor their network infrastructure to their specific needs.

Commonly Asked Questions about Ethernet/IP Protocol
The Common Industrial Protocol (CIP) is a versatile communication protocol used in industrial automation and control systems and encompasses a comprehensive suite of messages and services.
While Ethernet TCP/IP and EtherNet/IP share common physical and network layers (Ethernet and TCP/IP), EtherNet/IP adds specific features and protocols (CIP) tailored for industrial automation and real-time control applications.
Modbus TCP is a simpler, more straightforward protocol used primarily for basic data acquisition and control, while EtherNet/IP is a more complex and robust protocol designed for real-time industrial automation and control.
EtherNet/IP uses TCP port 44818 for explicit messaging and UDP port 2222 for implicit messaging. Communication over TCP port 44818 is typically used for non-time-critical data exchange where reliability is important while communication over UDP port 2222 is used for time-critical communications where speed is essential, such as controlling I/O devices.
