Get Waveform Subset (G Dataflow)

Boolean that determines whether the waveform subset extracted is an open or closed interval. For example, if t0 = 0, dt = 1, Y = {0, 1, 2}, start/duration format is Relative Time, start samples/time is 0, and duration is 2, an open interval returns {0, 1}. A closed interval returns {0, 1, 2}.

This input is available when you wire a waveform or digital waveform to waveform.

Default: True

Value that determines whether to retrieve the data value of the specified element or at a specified time.

This input is available when you wire a waveform or digital waveform to waveform.

Default: Samples

Waveform from which you want to retrieve a subset.

This input accepts an array of waveforms or an array of digital waveforms.

This input is available when you wire a waveform or digital waveform data type to digital data. If you wire a digital table to waveform, this input changes to digital data.

Set of digital data from which you want to retrieve a subset.

This input is available only when you wire a digital table to waveform. If you wire a waveform or digital waveform to digital data, this input changes to waveform.

Data element or time value where you want to start acquiring a waveform subset.

This input is available when you wire a waveform or digital waveform data type to digital data. If you wire a digital table to waveform, this input changes to start.

Default: 0

Data element or time value where you want to start acquiring a data subset.

This input is available only when you wire a digital table to waveform. If you wire a waveform or digital waveform to digital data, this input changes to start samples/time.

Default: 0

Amount of time to retrieve data or the number of elements of data you want to retrieve, depending on the start or duration format you select.

This input is available when you wire a waveform or digital waveform data type to digital data. If you wire a digital table to waveform, this input changes to number of samples.

Default: 1

Number of samples to include in the digital data subset.

This input is available only when you wire a digital table to waveform. If you wire a waveform or digital waveform to digital data, this input changes to duration.

Default: 0

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Subset of the provided waveform based on the parameters you specify.

This output is a digital waveform when you wire a digital waveform to waveform.

This output is available when you wire a waveform or digital waveform to waveform. If you wire a digital table to waveform, this output changes to digital data subset.

Subset of the provided digital data based on the parameters you specify.

This output is available only when you wire a digital table to waveform. If you wire a waveform or digital waveform to digital data, this output changes to waveform subset.

Actual data element when the subset was acquired.

This output is available when you wire a waveform or digital waveform to waveform.

Actual number of elements retrieved or the actual amount of time the data values were acquired.

This output is available when you wire a waveform or digital waveform to waveform.
