What is EtherNet/IP?
Developed in the late 1990s and released in early 2000, EtherNet/IP (Ethernet Industrial Protocol) is an application layer protocol that defines devices on a network as a series of objects. EtherNet/IP is one of several network protocols that operates under the common industrial protocol (CIP), an open application layer protocol. This protocol more recently has been extended to include CIP Security, which provides secure communications between devices on the factory floor. There are other CIP extensions as well, that include CIP Safety, CIP Energy, CIP Sync, and CIP Motion, each of which perform a specific service for the protocol.

EtherNet/IP is not to be confused with Ethernet. While they're both protocols, they work in different ways.

If you use the Internet, chances are you are familiar with the term Ethernet, as the hard-wire connection; however, that is just the simplest way to describe it. Ethernet is a physical networking protocol that is commonly used for commercial use. While Ethernet works well with local- and wide-area networks, it’s not very efficient for industrial factories that require more.

After the wide implementation and success of Ethernet in commercial use, Industrial Ethernet was born to support industrial infrastructure. EtherNet/IP is one type of Industrial Ethernet; others include Modbus TCP/IP, EtherCAT and PROFINET.

Note that Industrial Ethernet, and particularly EtherNet/IP, differs from standard Ethernet; the most important difference being real-time efficient communications. Ethernet and TCP/IP directly provide this, while EtherNet/IP does in conjunction with a managed switch based infrastructure. On the factory floor, you must have real-time efficient communications to maintain control and for accessing real time data to meet production and quality standards.

How EtherNet/IP Works
To understand how EtherNet/IP works, let's take a step back. There is a basic framework that shows how network communications work, called the Open Systems Interconnection Reference model or OSI. The OSI model works to show how protocols interact, including with Ethernet/IP. Here is a diagram
