PLC is a registered trade mark of Allen-Bradley for decades since the first PLC in the world.

It is a classic American story. Two brothers with a knack for invention and business, but no money. Another, older man who knew talent when he saw it and wash willing to invest in that talent. Hard work, luck and inventive genius combined to build a global company. The partnership between Dr.Stanton Allen and Lynde and Harry Bradley resulted in an industrial giant that continues to provide some of the basic tools keep industry humming. The growth from a two-man operation in rented space in someone's factory to a global industrial giant is the story of an entire century.

Allen-Bradley is named after Dr. Stanton Allen and Lynde Bradley

1901 - At the age of 23, Bradley develops a carbon disk compression type of crane control.

1903 - With financial backing from his friend Dr. Allen, he incorporates the Compression Rheostat Company; Dr. Allen is named president. Lynde Bradley's younger brother Harry joins the firm.

1909 - Lynde Bradley re-establishes the company in Milwaukee, Wisconsin with a new name: Allen-Bradley He is named president.

1972 - Allen-Bradley enters the drives business by purchasing TPC Drives, Inc.

1978 - PLC, introduced by Allen-Bradley, begins revolutionizing industrial control

1979 - DataHighway, the industry’s first plant floor network, is introduced

1985 - Rockwell International purchases Allen-Bradley Company for $1.651 billion

1994 - Allen-Bradley introduces DeviceNet, which quickly becomes the industry standard for plant floor networking and software in North America.

2003 - Allen-Bradley observes 100 years of hard work and fortitude in the automation industry

The high performance control platform for efficient plantwide control.

The high performance of the ControlLogix platform is due in part to the ControlLogix backplane which operates as a very fast NetLinx network. ControlLogix processors, I/O, and communications modules have the intelligence to act like independent nodes on that network. As a result, multiple processors, communication modules, and I/O can be mixed without restrictions. No processor is needed to perform bridging and routing of I/O, and as your system grows, the network permits distributing control to additional chassis.

Main Feature • Provides a modular, high performance control platform suited for sequential, process, drive, and motion control in any combination
• Allows you to mix multiple processors, networks, and I/O without restrictions
• Uses the same RSLogixTM 5000 programming environment as other Logix controllers for maximum program reusability and minimum training
• Connects to the NetLinx Open Network Architecture for more efficient communications and increased throughput
• Certified by TUV for SIL 1 and SIL 2 applications

FlexLogix is Rockwell Automation 's small to mid-range controller, which is an ideal alternative to the ControlLogix platform for certain applications , such as: standalone controller , small network linked distributed controller, small backup processor applications, specifically, ideal applications include RTU , small process , material-handling , and press control applications. FlexLogix uses the same Logix control engine and RSLogix 5000 programming software as found in other Logix platforms. FLEX I/O, the compact, DIN-rail mounted I/O found in thousands of industrial applications, is the perfect companion to this capable controller. FlexLogix supports the RSLogix 5000 function block library, making this an ideal, inexpensive multi-loop controller. FlexLogix uses NetLinx for communication to other devices on

Main Feature • Adds local control to FLEXTM I/O, the compact, modular DIN-rail mounted I/O system with integrated I/O interface and terminal strip, to reduce wiring.
• Provides a distributed architecture less vulnerable to a single point of failure because control does not depend on a single master controller.
• Reduce startup & simplify maintenance because control resides close to the machine
• Uses the same RSLogix 5000 programming environment as other Logix controllers for maximum program reusability and minimum training
• Connects to the NetLinx Open Network Architecture for more efficient communication and increased throughput
