Implementations§

Source§

impl ModbusProcessor

Source

pub fn new(transport: Arc<RtuTransport>) -> Self

Source

pub async fn process_request( &self, transaction_id: [u8; 2], unit_id: u8, pdu: &[u8], ) -> Result<Vec<u8>, RelayError>

Processes a Modbus TCP request by converting it to Modbus RTU, sending it over the transport, and then converting the RTU response back to Modbus TCP format.

§Arguments
  • transaction_id - The Modbus TCP transaction ID.
  • unit_id - The Modbus unit ID (slave address).
  • pdu - The Protocol Data Unit from the Modbus TCP request.
§Returns

A Result containing the Modbus TCP response as a vector of bytes, or a RelayError.
