Controllers Offer Improved Performance for Process, Discrete and Motion Applications

Description

Rockwell Automation has made two additions to its Allen-Bradley ControlLogix family of controllers, both leveraging the single design environment and networking protocol within the company’s Integrated Architecture system. The ControlLogix L73 and L75 programmable automation controllers (PACs) provide advanced memory, speed and processing capabilities for a wide range of control demands, from high-performance logic and motion to information-intensive process applications.

“The Integrated Architecture system is designed to help customers minimize cost, improve the flow of business and manufacturing data, and ultimately move towards plantwide optimization,” said Frank Kulaszewicz, vice president and general manager, Control and Visualization business, Rockwell Automation. “As part of that system, these new PACs have enhanced memory and processing capabilities that help improve production rates, boost overall equipment effectiveness, and provide more timely data for improved decision-making capabilities.”

For complex, high-performance motion applications, the ControlLogix L73 and L75 PACs interface seamlessly with motion drives through EtherNet/IP and SERCOS network interfaces. The controllers are capable of supporting as many as 100 axes, further simplifying synchronization of complex motion applications.

“PACs, such as the ControlLogix L73 and L75 controllers, lower the lifecycle costs and total cost of ownership for manufacturers by enabling a multidiscipline control system,” said Craig Resnick, research director, ARC Advisory Group. “In addition, they help manufacturers optimize communications based on industry standard network protocols, which removes additional barriers to collaboration and integration.”

The 1 GB secure digital card that ships with each controller provides improved data integrity, and faster reads and writes than previous CompactFlash technology. The ControlLogix L73 PAC is ideally suited for users requiring up to 16 MB of memory while the ControlLogix L75 PAC offers 32 MB of memory. 

New energy storage modules that ship with each controller will eliminate the need for lithium batteries, helping users avoid the maintenance and environmental issues associated with transporting and disposing batteries. A USB port provides faster uploads and downloads, firmware upgrades and online edits.

The controllers feature an on-board display to provide enhanced controller diagnostics and run-time information. Both models are currently available for shipping.
