DNP3 Protocol Python

The DNP3 Protocol Outstation Server and Master Client implemetation in Phyton.

we did a python wrapper for our DNP3 implementation using ctypes , and tested in Windows and linux x86_64.

in the package tests folder , you can find the server and client test programs.

using this, you can simulate complete dnp3 Server device(dnp3servertest.py) and client(dnp3clienttest.py).

install using - pip install dnp3protocol

Distributed Network Protocol 3 ( DNP3 ) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies.

Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems, where it is used by SCADA Master Stations (a.k.a. Control Centers), Remote Terminal Units (RTUs), and Intelligent Electronic Devices (IEDs). It is primarily used for communications between a master station and RTUs or IEDs.
