Example

Read tag from Allen-bradley CompactLogIx device

rseip::Result<()> { dst.put_u16_le(self.0); Ok(()) } fn bytes_count(&self) -> usize { 2 } } ">
use anyhow::Result;
use byteorder::{ByteOrder, LittleEndian};
use bytes::{BufMut, BytesMut};
use rseip::{client::Client, codec::Encodable, frame::cip::*};

#[tokio::main]
pub async fn main() -> Result<()> {
    let connection_path = EPath::from(vec![Segment::Port(PortSegment::default())]);
    let mut client = Client::connect("192.168.0.83").await?;
    let mr_request = MessageRouterRequest::new(
        0x4c,
        EPath::from(vec![Segment::Symbol("test_car1_x".to_owned())]),
        ElementCount(1),
    );
    let resp = client.send(mr_request, connection_path).await?;
    assert_eq!(resp.reply_service, 0xCC); // read tag service reply
    assert_eq!(LittleEndian::read_u16(&resp.data[0..2]), 0xC4); // DINT
    client.close().await?;
    Ok(())
}

struct ElementCount(u16);

impl Encodable for ElementCount {
    fn encode(self, dst: &mut BytesMut) -> rseip::Result<()> {
        dst.put_u16_le(self.0);
        Ok(())
    }
    fn bytes_count(&self) -> usize {
        2
    }
}

  • Future cannot be sent between threads safely

    Future cannot be sent between threads safely

    I have worked through the example you provided in the ReadMe, and it works great! I can read/write tags without a hitch.

    The issue arises when I attempt to create a background task to handle the reading/writing of tags. Rust Analyzer gives me the following error:

    future cannot be sent between threads safely
    the trait `std::marker::Send` is not implemented for `dyn std::future::Future<Output = Result<rseip::client::ab_eip::TagValue<i32>, ClientError>>`rustc
    [main.rs(18, 32): ]()future is not `Send` as it awaits another future which is not `Send`
    [spawn.rs(127, 21): ]()required by a bound in `tokio::spawn` 
    

    However, in the docs, it specifically says that ClientError is Send and TagValue is Send so long as T is also Send. This might just be my inexperience with tokio, but I am wondering if you could shed some light on how to do this properly.

    Here is my sample code:

    use rseip::client::ab_eip::*;
    use rseip::precludes::*;
    
    #[tokio::main]
    async fn main(){
        tokio::spawn(async move {
            background().await;
        });
    }
    
    async fn background() -> Result<()> {
        let mut client = AbEipClient::new_host_lookup("192.168.0.83")
            .await?
            .with_connection_path(PortSegment::default());
        let tag = EPath::parse_tag("test_car1_x")?;
        println!("read tag...");
        let value: TagValue<i32> = client.read_tag(tag.clone()).await?;
        println!("tag value: {:?}", value);
        client.write_tag(tag, value).await?;
        println!("write tag - done");
        client.close().await?;
        Ok(())
    }
    

    Thank you in advance!

  • Can not read a large template

    Can not read a large template

    let template = client.find_template(tag_info.1).await?; println!("template instance:\n{:?}", template);

    These statements work for a small (<500 bytes) templates, but do not work for a large (>500 bytes) templates:

    let info = client.read_template(&template).call().await?;
    println!("template definition:\n{:?}", info);

  • Future goals

    Future goals

    I happened across this lib just about the time you made your first commit. I am impressed by the rapid development.

    I am wonder what your future plans/goals are for this lib.

    I actually started writing some code to use your early work to read the template / structure data out of the processor. I then took another look at the repository, and BAM......already there!!!!! Impressive!!!!

  • Float values

    Float values

    Hi,

    I really appreciate this crate. Thank you for putting it together.

    I am new to Ethernet/IP and I have a question.

    When trying to read float type tags, I get a compiler error saying that Encode Decode are not implemented for f32. What's the best way to read and write f32 values for REAL type tags on AB PLCs?

    Thanks

  • I was not able to read a tag value in a controller..

    I was not able to read a tag value in a controller..

    I was not able to read a tag in a controller with this command:

    let mut client = AbEipConnection::new_host_lookup("xx.xx.xx.xx", OpenOptions::default()).await?; println!("read tag...{:?}", client); let tag1 = EPath::from_symbol("Cfg_LoSeverity"); println!("read tag...{:?}", tag1); let value: TagValue = client.read_tag(tag1.clone()).await?; println!("read tag...{:?}", value); client.close().await?;
