Parent Polymorphic VI: | HIL Task Read |
Requirements: | Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer |
Reads from other input channels of a HIL Task.
task in is a reference to a HIL Task instance that represents the created HIL task. This input must be wired to a valid HIL Task signal, as generated by a HIL Task Create Reader VI. |
num samples indicates the number of samples to read from the task buffer. Each "sample" consists of all the input channels specified when the task was created using HIL Task Create Reader VI. For example, if num samples is 5 and the task is configured to read 3 analog channels and 2 encoder channels, then the analog output buffer will contain 15 elements and the encoder output buffer will contain 10 elements. |
error in describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster in error out.
|
task out is a copy of the HIL Task instance passed to the task in input. |
|||||||
other values is the values read from the specified other channels when setting up in HIL Task Create Reader VI. |

error out contains error information. If the error in cluster indicated an error, the error out cluster contains the same information. Otherwise, error out describes the error status of this VI.

This VI only reads other inputs. When reading from mixed signal types, it is more efficient to use the
All input/output pairs of this function have direct feedthrough behaviour.

HIL Task Create Reader | Create a task for reading from analog, digital, encoder and/or other channels of a HIL board. The task allows other operations to be performed while the inputs are being read "in the background". The data is read into an internal circular "task buffer" from which it can be read at any time using the HIL Task Read VI. The size of this task buffer is determined by the sample in buffer input. |
