Get Started with Simulink PLC Coder

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, and Mitsubishi Electric GX Works3. 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).

Model and Generate Ladder Logic Code for Industrial Tank Level Control System

In this example, you use Simulink PLC Coder™ to model, simulate, and generate a ladder logic-based controller for the level control of an industrial tank. The ladder logic controls the tank level by using inputs from a low-level and high-level sensor in the tank to control a valve that empties the tank and a pump that fills the tank. After you simulate and verify the controller operation, generate code for your controller.

Generate Structured Text Code for State Machine Based Industrial Tank Level Controller

In this example, you use Stateflow® to model and implement a state machine controller to control the level of an industrial tank. Use state machines to design and maintain complex logic, ease handling complex coding constructs, and facilitate fault detection. Use Simulink PLC Coder™ to generate Structured Text code for the state machine controller. Verify the code by generating a test bench and using code traceability to trace the generated code to the corresponding Stateflow chart element.
