Referenced Models

Generate code for referenced models

You can generate IEC 61131-3 Structured Text code for a model reference hierarchy to achieve:

Incremental code generation — Generate code only if the model has changes since the code was previously generated
Modular development — Develop and maintain referenced model independently from the models that use it
Code reuse — Generate reusable code from a referenced model
