Configures a Script Trigger for edge triggering, setting the trigger source and edge to detect.

The waveform generator must not be in the Generating state when you call this node.

connector_pane_image
datatype_icon

session in

Handle that identifies your instrument session previously allocated by Initialize With Channels.

datatype_icon

trigger ID

Script Trigger used for triggering.

Default: Script Trigger 0

datatype_icon

source

Trigger source the waveform generator uses.

datatype_icon

edge

Edge to detect.

Name Value Description
Rising Edge 101 The node sets triggering for when the signal transitions from low level to high level.
Falling Edge 102 The node sets triggering for when the signal transitions from high level to low level.

Default: Rising Edge

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

session out

Reference to your instrument session to wire to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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