Expand description
ur20-modbus
is a Rust library for communicating
with the Modbus TCP fieldbus coupler Weidmüller UR20-FBC-MOD-TCP.
§Example:
use std::error::Error;
use ur20_modbus::Coupler;
#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
let addr = "192.168.0.222:502".parse()?;
let mut coupler = Coupler::connect(addr).await?;
let id = coupler.id().await?;
println!("Connected to {}", id);
coupler.set_output(
&ur20::Address {
module: 3,
channel: 2,
},
ur20::ChannelValue::Bit(true),
)?;
coupler.tick().await?;
Ok(())
}
