Send Software Trigger (G Dataflow)

Last Modified: March 3, 2017

Sends a software trigger to the switch module specified in the NI-SWITCH session.

Programming Patterns

When the trigger input parameter is set to Software Trigger Function using the niSwitch Configure Scan Trigger or the Trigger Input property, the scan does not proceed from a semicolon (wait for trigger) until this node is called.

session in

Control that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch 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

session out

Indicator that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node and used for all subsequent NI-SWITCH calls.

error out

Error information.

The node produces this output according to standard error behavior.
