Select Network Communications

Use specific PLC-5 controllers with network connections and install multiple

communication modules into the PLC-5 backplane to route control and

information data between the different networks.

The networking capabilities, led by EtherNet/IP, ControlNet, and DeviceNet

networks, allow information exchange between a range of devices and

computing platforms and operating systems. PLC-5 controllers come with

different network connections. Choose the network that best meets your

needs.

NetLinx Architecture

NetLinx open network architecture is the Rockwell Automation strategy of

using open networking technology for seamless, top-floor to shop-floor

integration. The networks in the NetLinx architecture - DeviceNet network,

ControlNet network and EtherNet/IP network - 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.

• 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.

• 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.

• DeviceNet network offers high-speed access to plant-floor data from a

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