profirust 0.1.0

PROFIBUS-DP compatible communication stack in pure Rust

What's this?

profirust is a pure-Rust PROFIBUS-DP compatible communication stack. PROFIBUS is an industrial bus protocol used to communicate with field devices like remote I/O, transducers, valves, drives, etc.

Project Status

profirust works well for the features it currently supports, however it has not proven itself in a real application yet. There are still some features missing which are needed for production use. Check the roadmap below.

At this time, profirust is developed as a spare time project. If you are interested in this project, help is gladly accepted in the following forms:

Code Contributions
Donation of PROFIBUS peripherals or other equipment for testing purposes
Funding of access to the needed IEC standards for improving compliance
Reporting any kinds of issues encountered while using profirust

Roadmap

Single-master bus up to 1 Mbaud
Cyclic communication with DP-V0 peripherals
Basic Diagnostics
Extended Diagnostics (DP-V0)
Multi-master bus
Bus error tracking
Bus discovery utilities
Reliable communication at 12 Mbit/s, so far up to 6 Mbit/s works fine
Communication with DP-V1 peripherals
Equidistant bus cycle
Isochronous bus cycle

Getting Started

This is a short guide for getting communication up and running with your PROFIBUS peripheral:

Find the GSD (generic station description) file for your peripheral. Usually, the manufacturer offers these for download somewhere.
Run the gsdtool to set up the configuration and parameterization of your peripheral:
```
cargo run -p gsdtool -- config-wizard path/to/peripheral.gsd
```
The configuration wizard will walk you through all the settings you need to make. At this stage, you also need to setup the modules of your peripheral. The wizard will then give you Rust code for configuring the peripheral options to your selected values.
Modify an example for your peripheral. Update the peripheral address. Then paste the PeripheralOptions block and I/O buffers that gsdtool emitted.
Run the example, ideally with RUST_LOG=trace to see bus communication. Hopefully, you should now be able to establish cyclic communication with your peripheral.
