Networks and Communications
Success Stories
Rockwell Automation introduced the NetLinx Open Network Architecture, a communication architecture that uses open networking technology for seamless shop-floor to top-floor integration. The networks that are part of this architecture are ControlNet, DeviceNet, and EtherNet/IP. These networks all share a common object model, a common application layer, and common device profiles. Because the NetLinx architecture provides these common elements, information can be transferred and understood among all three networks using simple bridges - an inexpensive and less complex option compared to gateways. The benefits are obvious: reduced cost and easier access to the information that users need to improve productivity.
What isn't always so obvious is the role that each of the networks play in the factory. Where and when is DeviceNet typically used? What are the similarities and differences between ControlNet and EtherNet/IP? While all of the networks offer similar features, each network has its own unique value propositions and will, as a result, be more appropriate for certain applications. These success stories help explain the primary roles of each network.
NetLinx
The fact that users need several networks in one plant (e.g. process, discrete, control-level, device-level, etc.) presents a new twist.
The drive to integrate the manufacturing enterprise from the simplest device to the highest-level information system represents a task which few networks.
DeviceNet
"And thanks to the control system on DeviceNet, someone can be in the control room and see what's happening on the entire machine."
When Complete Automation leader Rockwell Automation, launched its new Allen-Bradley ControlLogix platform, MJ Engineering were quick to identify its potential.
