IMAQdx Read Register VI
Installed With: NI Vision Acquisition SoftwareAccesses registers on the camera and reads a 32-bit value from the camera. Data is byte-swapped for little endian alignment after transfer.
 |
Session In is a unique reference to the camera, which you can obtain with the IMAQdx Open Camera VI. |

 |
Offset is the register location to access. Refer to the camera documentation for more information about camera-specific register ranges. Note: Use the Property Node Properties»Camera Information»Base Address to get the base address for your camera. |

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. |
||||||
 |
Value specifies the 32-bits of data read from the register offset. |

 |
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.
