Ethernet/IP


EtherNet/IP is an industrial Ethernet network that combines standard Ethernet technologies with the media-independent Common Industrial Protocol (CIP). EtherNet/IP is one of the leading industrial Ethernet networks in the world and is widely used in a range of industries including factory, hybrid and process. EtherNet/IP uses both of the most widely deployed collections of Ethernet standards –the Internet Protocol suite and IEEE 802 project – to define the features and functions for its transport, network, data link and physical layers. CIP uses its object-oriented design to provide EtherNet/IP with the services and device profiles needed for real-time control applications and to promote consistent implementation of automation functions across a diverse ecosystem of products. In addition, EtherNet/IP adapts key elements of Ethernet’s standard capabilities and services to the CIP object model framework, such as the User Datagram Protocol (UDP) which EtherNet/IP uses to transport I/O messages.

EtherNet/IP classifies Ethernet nodes as predefined device types with specific behaviors, among other things, allowing for: the transfer of basic I/O data via UDP-based implicit messaging; uploading and downloading of parameters, setpoints, programs and recipes via TCP Polled, cyclic and change-of-state monitoring via UDP; one-to-one (unicast), one-to-many (multicast), and one-to-all (broadcast) communication via IP; and EtherNet/IP makes use of TCP port number 44818 for explicit messaging and UDP port number 2222 for implicit messaging.

EtherNet/IP is one of four networks that adapt CIP to an industrial network along with DeviceNet, ControlNet and CompoNet. Portland Engineering works extensively with all four network protocols on controls systems that use them all individually or in combination. Our extensive, hands on experience with these networks provides us with a deep knowledge of how these networks operate individually as well as how to integrate them with one another successfully.
