Struct MbapHeader 

pub struct MbapHeader {
    pub transaction_id: u16,
    pub protocol_id: u16,
    pub length: u16,
    pub unit_id: u8,
}

Modbus TCP Application Data Unit (ADU) Header (MBAP).

Fields

transaction_id: u16

Identification of a Modbus Request/Response transaction.

protocol_id: u16

Number of remaining bytes in the message (Unit ID + PDU).

unit_id: u8

Identification of a remote server on a non-TCP/IP network.

Implementations

impl MbapHeader

pub fn new(transaction_id: u16, length: u16, unit_id: u8) -> Self

Arguments

• transaction_id - The transaction ID for the Modbus message.
• protocol_id - The protocol identifier (should be 0 for Modbus).
• length - The length of the remaining message (Unit ID + PDU).
• unit_id - The unit identifier for the target slave device.

Returns

A new MbapHeader instance.
