Python PROFIBUS module

Project description

pyprofibus - PROFIBUS-DP stack

pyprofibus is an Open Source PROFIBUS-DP stack written in Python.


What hardware can pyprofibus be run on? Please read the hardware documentation for more information:

pyprofibus hardware documentation

Speed / Baud rate

The achievable Profibus-DP speed depends on the hardware that it runs on and what kind of serial transceiver is used. There is no software side artificial limit.

Please see the pyprofibus hardware documentation


pyprofibus comes with a couple of examples that can teach you how to use pyprofibus in your project.

  • Example that runs pyprofibus without any hardware. This example can be used to play around with pyprofibus.
    • example_dummy.conf
  • Example that runs pyprofibus as master connected to an ET200S as slave.
    • example_et200s.conf
  • Example that runs pyprofibus as master connected to an S7-315-2DP as slave.
    • example_s7-315-2dp.conf
