niseCfg Add Object (To Virtual Device » IVI Device Ex) (G Dataflow)

Last Modified: September 16, 2017

Adds an IVI device with a specific driver and topology to a virtual device configuration.

connector_pane_image
datatype_icon

driver name

Name of the driver of the IVI device. Valid values are NI-DAQmx or IVI.

datatype_icon

virtual device

Handle that identifies the virtual device previously allocated by niseCfg Get Virtual Device.

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

IVI logical name

IVI logical name (case sensitive) of the switch to configure.

datatype_icon

comment

Information to document about the IVI device setup for reference or grouping and filtering.

datatype_icon

topology name

Name of the topology for the IVI device.

datatype_icon

virtual device out

Reference to the virtual device from the configuration previously allocated by niseCfg Get Virtual Device.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

IVI device

Reference to the IVI device on the virtual device to configure.
