Struct ReadBitCommand 

pub struct ReadBitCommand { /* private fields */ }

Command for reading a single bit from PLC memory.

Implementations

impl ReadBitCommand

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

Creates a new read bit command.

Arguments

• destination - Destination node address
• source - Source node address
• sid - Service ID for request/response matching
• area - Memory area to read from (must support bit access)
• word_address - Word address
• bit - Bit position (0-15)

Errors

Returns an error if:

• The memory area doesn’t support bit access (DM)
• The bit position is > 15

Example

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

let cmd = ReadBitCommand::new(
    NodeAddress::new(0, 10, 0),
    NodeAddress::new(0, 1, 0),
    0x01,
    MemoryArea::CIO,
    100,
    5,
).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.
