Radical new approach to motion control?
While traditional motion control systems typically have their own proprietary text based programming languages, ControlLogix uses standard 'ladder logic' programming.
The Allen-Bradley ControlLogix system from complete automation leader Rockwell Automation takes a radical new approach to motion control While traditional motion control systems typically have their own proprietary text based programming languages (there are more than 60 in the EU alone), ControlLogix has the motion functionality integrated into the PLC and uses standard 'ladder logic' programming
The key to the ControlLogix system is the Logix 5550 controller, a highly functional industrial processor, which provides a modular and flexible solution across a wide range of applications.
This powerful controller provides easy to use programming based on the IEC 1131-3 specification.
The instruction set maintains the look and feel of existing Allen-Bradley PLC's, so there is no need for users to learn different programming skills.
The Logix 5550 controller offers highly integrated motion control by simply inserting standard motion instructions within the controller's ladder diagram.
There is only one software tool to learn and one program to maintain for both motion and sequential control.
The controller provides all the communication and path information needed to integrate multiple motion axes into a single cohesive system.
This results in faster application development and integration, higher system performance and much simpler start up and maintenance.
Synchronised, distributed processing provides excellent performance and integration.
In the case of a motion command, the Logix 5550 controller executes ladder based instructions and a motion trajectory planner, while the servo module executes a fine planner and closes the position and velocity loop.
Common execution of the motion and sequential commands ensures synchronisation.
The 200 microsecond fine planner, position loop and velocity loop closure for all axes in the ControlLogix chassis provide precise control.
Further Logix 5550 controllers, each capable of controlling up to 32 axes, can be added to the chassis to increase the processing power as needed.
There are 27 motion commands in the controllers instruction set, such as, homing, jogging, point-to-point positioning, gearing, high speed position registration, auto-tuning and a powerful cam profile function that automatically takes the smoothest route through a number of points.
RS Logix 5000 programming software is all that is needed to fully configure an integrated motion solution.
Features in the software automate what previously required a manual motion control development process.
There is wizard driven axis configuration and commissioning, drive connection diagnostics and auto tuning, ladder based application programming, online editing and monitoring.
The ControlLogix system establishes a new benchmark in motion control, it offers enhanced productivity together with ease of maintenance, and provides stability across a wide range of applications.
It introduces the benefits of motion programming based on European standards and dispels the 'black art' reputation that is sometimes associated with the implementation of motion systems. Request a free brochure from Rockwell Automation Anorad ...
