Programmable automation controllers

The Allen-Bradley ControlLogix 5570 Series programmable automation controllers (PACs) from Rockwell Automation include the ControlLogix 5571, 5572, 5572S, 5573, 5573S, 5574 and 5575 controllers. The PACs feature enhanced process, motion, safety and information capabilities, and leverage a common design environment and networking of the Rockwell Automation Integrated Architecture system. For process applications, the new ControlLogix controllers significantly improve the amount of information that can be exchanged between the control and supervisory layers, while allowing more control strategies to be executed, the company says. This helps boost system performance while enhancing access to real-time information for improved productivity. For motion applications, the ControlLogix 5570 series controllers provide high-speed axis and trajectory planning, making them ideal for synchronizing complex motion applications. Each controller is capable of supporting more than 100 axes of motion and seamlessly integrates through EtherNet/IP and SERCOS network interfaces. For discrete applications, the new ControlLogix controllers provide two to three times faster scan times and a range of memory options from two to 32 MB, according to the company. All ControlLogix 5570 Series controllers are equipped with on-board display features that provide enhanced diagnostics and run-time information to help ease troubleshooting and increase uptime. The controllers also have improved security features, including improved data integrity and faster data transference with a one-GB secure digital card.
