Networks & Communications

We offer network solutions to connect your automation products to each other and to the rest of your enterprise. We can help you select the best network architecture and provide you with design and implementation guidance. We offer a wide variety of devices, communication interfaces, physical media and connecting products to help you get the most out of your control system.

EtherNet/IP Network

RA-NC-01 EtherNet/IP Connected Products
Infrastructure (Media & Switches)
The EtherNet/IP™ Network provides plant-wide network systems using open, industry-standard networking technologies. It enables real-time control and information in discrete, continuous process, batch, safety, drive, motion, and high availability applications. The EtherNet/IP network connects devices such as motor starters and sensors to controllers and HMI devices and on into the enterprise. It supports non-industrial and industrial communications on a common network infrastructure.

ControlNet Network

RA-NC-02 ControlNet Connected Products
ControlNet Media
The ControlNet™ network is an open control network that meets the demands of real-time, high-throughput applications. ControlNet supports controller to controller interlocking and real-time control of I/O, drives and valves. It also provides control networking in discrete and process applications including high-availability applications.

DeviceNet Network

RA-NC-03 DeviceNet Connected Products
DeviceLogix-Enabled Products
DeviceNet Media
The DeviceNet™ Network provides open, device-level control and information networking for simple industrial devices. It supports communication between sensors and actuators and higher-level devices such as programmable controllers and computers. With power and signal in a single cable, it offers simple and cost-effective wiring options.
