Crate ur20_modbus

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(())
 }
