rPLC - PLC programming for Linux in Rust

rPLC project allows to write PLC programs for Linux systems in Rust using classical PLC programming approach.

rPLC supports Modbus and OPC-UA input/output protocols out-of-the-box and can be easily extended with custom I/O as well.

rPLC is a part of EVA ICS open-source industrial automation eco-system.

A quick example

use rplc::prelude::*;

mod plc;

#[plc_program(loop = "200ms")]
fn tempmon() {
    let mut ctx = plc_context_mut!();
    if ctx.temperature > 30.0 {
        ctx.fan = true;
    } else if ctx.temperature < 25.0 {
        ctx.fan = false;
    }
}

fn main() {
    init_plc!();
    tempmon_spawn();
    run_plc!();
}
