- Python 3.6.8 (32-bit) — newer 3.x works for most examples except OpenOPC-DA COM
- KepServerEX / Schneider OPC servers etc. (optional, for OPC-DA live tests)
- USB/serial + RS485 transceiver for Modbus RTU
pip install -r requirements.txt(on Windows for OPC-DA also install pywin32)- Open notebooks in Jupyter:
jupyter notebook - Follow instructions inside each
.ipynb - For scripts:
python filename.py
See OPC/OPC-UA/ for client/server examples.
See MODBUS/ for TCP and RTU examples.
See MQTT/ for publisher/subscriber and bridge examples.
See OPC/OPC-DA/ — requires Windows + GrayBox wrapper + pywin32.
N/A — Python-based repo.
- Wrong Python bitness for OPC-DA → use 32-bit Python 3.6 with pywin32 from releases
- GrayBox DLL not registered →
regsvr32 gbda_aut.dllas admin - Check notebook paths after cloning (spaces in folder names are preserved)
