Implementations

impl ReadWordCommand

pub fn new( destination: NodeAddress, source: NodeAddress, sid: u8, area: MemoryArea, word_address: u16, count: u16, ) -> Result<Self>

Creates a new read word command.

Arguments

• destination - Destination node address
• source - Source node address
• sid - Service ID for request/response matching
• area - Memory area to read from
• address - Starting word address
• count - Number of words to read (1 to maximum area capacity)

Errors

Returns an error if count is 0 or exceeds the available capacity for the target area.

Example

use omron_fins::{ReadWordCommand, MemoryArea, NodeAddress};

let cmd = ReadWordCommand::new(
    NodeAddress::new(0, 10, 0),
    NodeAddress::new(0, 1, 0),
    0x01,
    MemoryArea::DM,
    100,
    10,
).unwrap();

pub fn sid(&self) -> u8

Returns the service ID.

pub fn to_bytes(&self) -> Vec<u8>

Serializes the command to bytes for transmission.
