IMAQdx Configure Grab VI
Installed With: NI Vision Acquisition SoftwareConfigures and starts a grab acquisition. A grab performs an acquisition that loops continually on a ring of buffers. Use the grab VI for high-speed image acquisition. Use the IMAQdx Grab VI to copy an image out of the buffer. If you call this VI before calling the IMAQdx Open Camera VI, the IMAQdx Configure Grab VI uses cam0 by default. Use the IMAQdx Unconfigure Acquisition VI to unconfigure the acquisition.

Session In specifies the name of the camera you wish to reset. The default value is cam0. |

error in describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. Explain Error (or Explain Warning) gives more information about the error displayed.

Session Out is a unique reference to the camera. Session Out is the same as Session In. |

 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI produces. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
