pyprofibus - PROFIBUS-DP stack
==============================
pyprofibus is an Open Source `PROFIBUS-DP <https://en.wikipedia.org/wiki/Profibus>`_ stack written in Python.
`pyprofibus home <https://bues.ch/a/profibus>`_
`Git repository <https://bues.ch/cgit/pyprofibus.git>`_
`Github repository <https://github.com/mbuesch/pyprofibus>`_
Hardware
========
pyprofibus is able to run on any machine that supports Python. It also runs on embedded machines such as the `Raspberry Pi <https://en.wikipedia.org/wiki/Raspberry_Pi>`_ or even tiny microcontrollers such as the `ESP32 <https://en.wikipedia.org/wiki/ESP32>`_ (Micropython).
Please read the hardware documentation for more information:
`pyprofibus hardware documentation <doc/hardware.rst>`_
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 <doc/hardware.rst>`_
Examples
========
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.
* examples/example_dummy_oneslave.py
* examples/example_dummy_oneslave.conf
* examples/example_dummy_twoslaves.py
* examples/example_dummy_twoslaves.conf
* examples/example_dummy_inputonly.py
* examples/example_dummy_inputonly.conf
* Example that runs pyprofibus as master connected to an ET200S as slave.
* examples/example_et200s.py
* examples/example_et200s.conf
* Example that runs pyprofibus as master connected to an S7-315-2DP as *slave*.
* examples/example_s7-315-2dp.py
* examples/example_s7-315-2dp.conf
Dependencies
============
* `Python <https://www.python.org/>`_ 3.5 or later.
* Or alternatively `Micropython <https://micropython.org/>`_. Please see the `pyprofibus Micropython help <micropython/README.rst>`_ for more information.
