Rust Modbus

Modbus implementation in pure Rust.

Usage

Add modbus to your Cargo.toml dependencies:

[dependencies]
modbus = "1.1"

Import the modbus crate and use it's functions:

use modbus::{Client, Coil};
use modbus::tcp;

let mut client = tcp::Transport::new("192.168.0.10");

client.write_single_coil(1, Coil::On).unwrap();
client.write_single_coil(3, Coil::On).unwrap();

let res = client.read_coils(0, 5).unwrap();

// res ==  vec![Coil::Off, Coil::On, Coil::Off, Coil::On, Coil::Off];

See the documentation for usage examples and further reference and the examples directory for a commandline client application.
