ControlLogix Standard Controllers

Bulletin 1756 ControlLogix® Standard Controllers are suitable for process, slcpowersupplymotion, discrete, and high-availability applications. As part of the Rockwell Automation® Integrated Architecture™ system, the L6 and L7 models use RSLogix™ 5000 programming software and common network protocols, and they offer common information capabilities. These high-performance controllers provide a common control engine with a common development environment for all control disciplines. Consider these controllers for more sophisticated machines and for connectivity to business systems.

Applications

Our ControlLogix® controllers offer the memory, speed, and processing capabilities to meet the demands of basic plant floor applications to high-performance process and motion applications.

For process applications, these controllers:

  • offer increased capacity, letting you execute more control strategies in each task
  • significantly improve the amount of information to be exchanged between control and supervisory layers
  • offer a significant improvement in the performance of redundant control applications

For motion applications, these controllers:

  • provide high-speed motion command and axis trajectory planner execution for complex, high-performance motion applications
  • are optimized for control of high performance motion drives on EtherNet/IP™ or Sercos™ interface
  • support as many as 100 axes of integrated motion

For discrete applications, these controllers:

  • significantly improve controller scan times using a faster dual-core CPU
  • offer improved communication rates
  • provide faster cross-loading for redundancy systems
