Lightweight PROFINET discovery and commissioning tool written in Python.

FreeNeta allows you to quickly discover and configure PROFINET devices using DCP without needing heavyweight vendor tools.

The project started because downloading Siemens PRONETA requires creating an account and registering personal details just to access a "free" tool. FreeNeta aims to provide a simple, lightweight, open-source alternative for basic discovery and diagnostics.

FreeNeta is meant as a lightweight quick-scan tool, not a full replacement for Proneta.
