IMAQdx Read Register (G Dataflow)

Last Modified: March 25, 2019

Accesses registers on the camera and reads a 32-bit value from the camera.

Data is byte-swapped for little-endian alignment after transfer.

connector_pane_image
datatype_icon

session in

Unique reference to the camera, which you can obtain with the IMAQdx Initialize node.

datatype_icon

error in

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

datatype_icon

offset

Register location to access.

Refer to the camera documentation for more information about camera-specific register ranges. Use the Property Node Properties»Camera Information»Base Address to get the base address for your camera.

datatype_icon

session out

Unique reference to the camera. session out is the same as session in.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

datatype_icon

value

32-bits of data read from the register offset.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
