Introduces a Python Plant Model: a flexible component for Python-defined plants (e.g. control theory, mechatronics, etc).

Features:

  • Configurable I/O sizes
  • Python process() method called each step
  • Error handling without freezing UI
  • Examples included

Placed in src/components/other/plant_model/

Tested: multi-instance, reloads, exceptions, NumPy returns.
Dependencies: Python 3 dev libs.

More examples (PID plant etc.) have been sent to the forum.

Dependencies

  • Python 3 development headers/libraries (for linking -lpython3.x)
  • Tested with Python 3.12

Testing done

  • Multiple instances (shared & separate scripts)
  • Reload file content → behavior updates immediately
  • Raise exceptions / wrong return types → error dialog appears without freezing UI
  • Add/remove pins → component resizes correctly, no ghost areas
  • NumPy arrays as return values work (via PySequence interface)

Please contact t me if you have any questions.
