Simulink PLC Coder

Generate IEC 61131-3 Structured Text and Ladder Diagrams for PLCs and PACs

Simulink® PLC Coder™ generates hardware-independent IEC 61131-3 Structured Text and Ladder Diagrams from Simulink models, Stateflow® charts, and MATLAB® functions. Structured Text is generated in PLCopen XML and other file formats supported by widely used integrated development environments (IDEs) including 3S-Smart Software Solutions CODESYS, Rockwell Automation® Studio 5000, Siemens® TIA Portal, and OMRON® Sysmac® Studio. Ladder diagrams are generated in file formats supported by Rockwell Automation Studio 5000. As a result, you can compile and deploy your application to numerous programmable logic controller (PLC) and programmable automation controller (PAC) devices.

Simulink PLC Coder generates test benches that help you verify the Structured Text and Ladder Diagrams using PLC and PAC IDEs and simulation tools. It also provides code generation reports with static code metrics and bidirectional traceability between model and code. Support for industry standards is available through IEC Certification Kit (for IEC 61508 and IEC 61511).
