EtherNet/IP
Open Industrialized Protocol for Configuration, Data
Collection/Acquisition and Control
Ethernet TCP/IP, the same network used by the World Wide Web and most email systems, is Rockwell
Automation’s network choice between the plant floor and your business systems because it provides easy
access to various enterprise information systems. EtherNet/IP utilizes standard EtherNet TCP/IP – including
protocol, chips, and media – and adds the IP, Industrial Protocol, based on the NetLinx architecture on top.
The result: Configure, Collect Data and Control your plant with EtherNet/IP and enjoy the benefits of both
the standard Ethernet TCP/IP and the NetLinx architecture.
ControlNet
High-Speed, Deterministic and Repeatable Performance
ControlNet is an open network managed by ContolNet International, Ltd., an independent vendor’s
organization. ControlNet is a real-time, control network utilizing the producer/consumer model that
provides high-speed transport of both time-critical I/O data and messaging data, including upload/download
of programming and configuration data and peer-to-peer messaging – all in one, single physical media link.
ControlNet’s high-speed (5Mbits/sec) control and data capabilities significantly enhance I/O performance
and peer-to-peer communication in any system or application where it is employed.
ControlNet is highly deterministic because it has the ability to reliably predict when data will be delivered.
ControlNet is also renowned for its repeatable nature which guarantees that transmit times are unfailingly
constant and unaffected by devices connecting to, or data leaving, the network. These are critical
requirements for ensuring dependable, synchronized and coordinated real-time performance
DeviceNet
Lower Costs, Faster Installation and Reduced Downtime
DeviceNet is an open network managed by the Open DeviceNet Vendor Association with more than 400
member companies. Based on proven Controller Area Network (CAN) technology and the
producer/consumer model, it is a cost-effective solution for low-level, industrial device networking and an
effective way to provide access to the intelligence present in those devices. A DeviceNet network allows
you to connect devices directly to plant-floor controllers over an open network without the need to hard-
wire each device into I/O modules. This direct connectivity reduces costly and time-consuming wiring.
DeviceNet’s 64-node, multi-drop network uses a single cable to interface devices up to 500m (164 ft) from
your control system, rather than wiring each device to an I/O chassis. Intelligent devices on this network
offer improved and more comprehensive diagnostics to reduce system downtime. These features – reduced
wiring, reduced start-up time, less downtime – are our pledge to bring you the most advanced networking
solutions available.
