You use separate interface modules to connect to different networks.

y The 1768-L43 controller has a built-in serial port.

y Add a 1768-ENBT module for EtherNet/IP communications.

y Add a 1769-SDN scanner to connect to DeviceNet devices.

The individual communication interface modules allow for more system flexibility, greater

communications connections, and more distributed I/O connections.

NetLinx Open Network Architecture is the Rockwell Automation strategy of using open

networking technology for seamless, top-floor to shop-floor integration. The NetLinx-

based networks – DeviceNet, ControlNet, and EtherNet/IP – all use the Common

Industrial Protocol, so they speak a common language and share a universal set of

communication services. NetLinx architecture, part of the Integrated Architecture,

seamlessly integrates all the components in an automation system from a few devices on

one network to multiple devices on multiple networks including access to the Internet –

helping you to improve flexibility, reduce installation costs, and increase productivity.

y The EtherNet/IP network is an open industrial networking standard that supports implicit

and explicit messaging and uses commercial, off-the-shelf Ethernet equipment and

physical media.

y The ControlNet network allows intelligent, high-speed control devices to share the

information required for supervisory control, work-cell coordination, operator interface,

remote device configuration, programming, and troubleshooting.

y The DeviceNet network offers low-cost, high-speed access to plant-floor data from a

broad range of plant-floor devices and a significant reduction in wiring.
