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.
