Struct DaqCapture 

pub struct DaqCapture {
    pub busy: bool,
    pub active: bool,
    pub error: bool,
    pub error_message: String,
    pub data: Option<CaptureData>,
    /* private fields */
}

DAQ Capture function block for NI triggered recordings.

Fields

busy: bool

True while the FB is executing (from arm through data retrieval).

active: bool

True when the DAQ is armed and waiting for the hardware trigger.

error: bool

True when an error occurred.

error_message: String

Error description (empty when no error).

data: Option<CaptureData>

Captured data. Some after a successful capture, None otherwise.

Implementations

impl DaqCapture

pub fn new(daq_fqdn: &str) -> Self

Create a new DaqCapture function block.

pub fn is_busy(&self) -> bool

The FB is busy running.

pub fn is_error(&self) -> bool

The last requested command resulted in an error.

pub fn start(&mut self, client: &mut CommandClient)

Start a new capture sequence (Arm the DAQ).

pub fn reset(&mut self)

Stop/Cancel the capture and return to idle.

pub fn set_trigger_delay(&mut self, client: &mut CommandClient, delay_ms: u32)

Update the Timer-trigger delay for this DAQ.

Only valid when the FB is idle (i.e. before start() is called or after the capture has completed). If called while the FB is busy, the request is silently dropped — call reset() first if you need to abort and reconfigure. The change is also rejected server-side if the DAQ has been armed by another caller.

Has no effect on DAQs whose trigger type is not timer.

pub fn tick(&mut self, timeout_ms: u32, client: &mut CommandClient)

Execute one scan cycle of the DAQ capture state machine.

Trait Implementations

impl Default for DaqCapture

fn default() -> Self

Returns the “default value” for a type.
