Model Architecture and Design

Design models intended for Simulink® PLC Coder™ code generation

When developing Simulink models for generating structured text or ladder logic code, consider:

  • Blocks and libraries for which code generation is supported. For a list of Simulink blocks supported for PLC code generation, see Simulink Block List (PLC Code Generation).

  • Setting up a model for fixed point data type code generation.

  • Setting up a multirate model for code generation.

  • Setting up a MATLAB Function for code generation.

  • Existing limitations when using Simulink PLC Coder to generate either structured text or ladder logic code.
