pyprofibus - PROFIBUS-DP stack
pyprofibus is an Open Source PROFIBUS-DP stack written in Python.
Hardware
pyprofibus is able to run on any machine that supports Python. It also runs on embedded machines such as the Raspberry Pi or even tiny microcontrollers such as the ESP32 (Micropython).
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
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 3.5 or later.
- Or alternatively Micropython. Please see the pyprofibus Micropython help for more information.
