Send Software Edge Trigger (G Dataflow)

Version:
Last Modified: September 27, 2017

Forces a particular edge, pattern match, or software trigger to occur.

This node applies only to the triggers listed below, and it is valid only if the particular trigger has been configured for edge, pattern match, or software triggering:

  • Start Trigger
  • Reference Trigger
  • Advance Trigger
  • Script Trigger
  • Stop Trigger

For edge or pattern match triggers, you can use this node as a software override.

connector_pane_image
datatype_icon

session in

Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

datatype_icon

trigger

The trigger you want to assert.

You can select Start Trigger, Reference Trigger, Advance Trigger, Script Trigger, or Stop Trigger as the value for this control.

datatype_icon

trigger id

The specified details of the script trigger.

This parameter can be ScriptTrigger0, ScriptTrigger1, ScriptTrigger2, or ScriptTrigger3; or you can leave this parameter blank for the Start, Reference, Advance, and Stop triggers.

spd-note-note
Note  

PXI-6544/6545/6547/6548 devices do not support ScriptTrigger 3.

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

Handle that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
