iec104-python

High-level Python module for simulating SCADA systems and RTUs communicating via the IEC 60870-5-104 protocol. Built with lib60870-C and pybind11.

🚀 Quick Start

Installation

pip install c104

Basic Usage

SCADA Unit (Client):

import c104
client = c104.Client()
connection = client.add_connection(ip="127.0.0.1", port=2404, init=c104.Init.INTERROGATION)
station = connection.add_station(common_address=47)
point = station.add_point(io_address=11, type=c104.Type.M_ME_NC_1)
client.start()

Remote Terminal Unit (Server):

import c104
server = c104.Server(ip="0.0.0.0", port=2404)
station = server.add_station(common_address=47)
station.add_point(io_address=11, type=c104.Type.M_ME_NC_1, report_ms=5000)
server.start()

See the examples folder for more detailed scenarios.

🛠 Installation & Build

Standard Install

Install via PyPI: pip install c104 or from Git: pip install c104@git+https://github.com/fraunhofer-fit-dien/iec104-python.git

Building from Source

System Requirements: Python $\ge 3.9, <= 3.15$.

1. Clone & Init:

   git clone --depth=1 --branch=main https://github.com/Fraunhofer-FIT-DIEN/iec104-python.git
   cd iec104-python
   git submodule update --init

2. Build Wheel:

   • Linux: python3 -m pip wheel .
   • Windows: python3 -m pip wheel . (requires VS 2022 Build Tools)
   • Multi-version (Linux Docker): /bin/bash ./bin/linux-build.sh

3. Custom Windows Build (MSVC):

   cmake -DCMAKE_BUILD_TYPE=Release -G "Visual Studio 17 2022" -B cmake-build-release -A x64 -DPython_EXECUTABLE=C:\PATH_TO_PYTHON\python.exe
   &"C:\Program Files\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin\MSBuild.exe" /m /p:Platform=x64 /p:Configuration=Release c104.sln /t:Rebuild

   Set a valid PATH_TO_PYTHON, if you have multiple python versions.
   Set a valid path to MSBuild.exe unless msbuild is already in path.
