pub struct MultipleReadCommand { /* private fields */ }

Command for reading from multiple memory areas.

Implementations

impl MultipleReadCommand

pub fn new( destination: NodeAddress, source: NodeAddress, sid: u8, specs: Vec<MultiReadSpec>, ) -> Result<Self>

Creates a new multiple memory area read command.

Arguments

• destination - Destination node address
• source - Source node address
• sid - Service ID for request/response matching
• specs - List of read specifications

Errors

Returns an error if specs is empty, any bit area doesn’t support bit access, or any bit position is > 15.

Example

use omron_fins::{MultipleReadCommand, MultiReadSpec, MemoryArea, NodeAddress};

let cmd = MultipleReadCommand::new(
    NodeAddress::new(0, 10, 0),
    NodeAddress::new(0, 1, 0),
    0x01,
    vec![
        MultiReadSpec { area: MemoryArea::DM, address: 100, bit: None },
        MultiReadSpec { area: MemoryArea::DM, address: 200, bit: None },
    ],
).unwrap();

pub fn sid(&self) -> u8

Returns the service ID.

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

Serializes the command to bytes for transmission.
