This introductory model shows the code generated for a hierarchical subsystem consisting of other Simulink subsystems.
This model contains a hierarchical subsystem containing other virtual subsystems.
You can generate PLC Structured Text code for this subsystem by right-clicking on the subsystem block and select PLC Code -> Generate Code for Subsystem Alternatively, you can use the following command generatedFiles = plcgeneratecode('plcdemo_hierarchical_virtual_subsystem/HierarchicalSubsystem');
After the code generation, the Diagnostic Viewer window is displayed with hyperlinks to the generated code files. You can open the generated files by clicking on the links.
