MathWorks (www.mathworks.com) unveiled its latest product that generates IEC 61131 Structured text (“ST”) for programmable automation controller (“PAC”) and programmable logic controller (“PLC”) devices, the Simulink PLC Coder. It enables Model-Based Design for power generation and manufacturing equipment controlled by PACs and PLCs.

With the new PLC Coder from Simulink, the code for industrial control systems such as supervisory and closed-loop control applications can be automatically generated by machine engineers. Automatic code generation, the Model-Based Design’s integral part, reduces validation and overall development time and helps avoid errors related with traditional hand coding.

“Industrial automation is a competitive field as companies continuously seek ways to innovate and develop more complex mechatronic industrial systems. Our customers recognize that Model-Based Design with automatic code generation is the best way to design and validate these complex systems that span electrical, mechanical and control system domains. This approach enables them to succeed,” said Tony Lennon, The MathWorks’ industrial automation and machinery industry manager.

The new Simulink PLC Coder creates source code in structured text from Simulink models, Embedded MATLAB code, and Stateflow charts. It uses an integrated development environment (“IDE”) from an industrial automation seller to compile and run the code on a PAC or PLC commonly used for machine control.

MathWorks is working hand in hand with leading industrial automation sellers like B&R (www.br-automation.com) and Rockwell Automation (www.rockwellautomation.com) to assist users integrate Model-Based Design to their industrial equipment development efforts.

Rockwell Automation’s strategic alliance manager, Jason Weber said: “By collaborating with The MathWorks, our customers gain the ability to use Model-Based Design for developing PAC applications enhancing machine performance. Model-Based Design aligns closely with our Virtual Design and Production strategy which allows customers to speed time to market, reduce engineering costs and further validate machines before production.”

“Model-Based Design opens a new development approach for customers validating the integration of electromechanical and control systems for industrial equipment. Automatic code generation speeds up testing and deployment to the final system. Simulink PLC Coder complements B&R Automation Studio Target for Simulink, letting our customers chose between generating structured text and C-code, depending on the needs of their application,” said Philipp Wallner, B&R Industrial Automation’s Mechatronics Technologies lead developer.
