Rockwell Automation

Rockwell Automation's flagship PLC platform is the Allen-Bradley ControlLogix series, which is widely used in factory automation across North America. They also offer the CompactLogix line for smaller applications and the MicroLogix series for entry-level control. These systems are programmed using Rockwell's Studio 5000 Logix Designer software.

Rockwell Automation and Siemens are the two largest industrial automation companies in the world, with Rockwell dominating the North American market and Siemens holding a stronger position in Europe and Asia. Rockwell's Allen-Bradley controls ecosystem is known for its user-friendly integration and standardized architecture, while Siemens offers the TIA Portal platform with its SIMATIC S7 PLCs. The choice between the two often comes down to geographic location and existing plant infrastructure.

Rockwell Automation trades on the New York Stock Exchange under the ticker symbol ROK. The company, headquartered in Milwaukee, Wisconsin, has been publicly traded since its spin-off from Rockwell International in the 1990s. It is a component of the S&P 500 index.

Allen-Bradley controllers by Rockwell Automation are used across discrete manufacturing, process industries, and heavy industry, with particularly strong adoption in automotive manufacturing, food and beverage processing, and pharmaceuticals. The company's FactoryTalk software suite provides the supervisory control and data acquisition (SCADA) layer. Rockwell's ecosystem is deeply embedded in North American manufacturing, where it holds the largest market share.
