Configure Trigger Slope (G Dataflow)

Version:
Last Modified: September 16, 2017

Sets the trigger slope to either rising edge (positive) or falling edge (negative) polarity.

connector_pane_image
datatype_icon

session in

Instrument identifier from previous NI-DMM nodes.

Default: None

datatype_icon

slope

Polarity of the trigger signal on which the measurement is triggered.

NI-DMM sets the Trigger Slope property to this value.

Name Description
Rising Edge The driver triggers on the rising edge of the trigger signal. The Trigger Slope property is set to POSITIVE.
Falling Edge The driver triggers on the falling edge of the trigger signal. The Trigger Slope property is set to NEGATIVE.

Default: Falling 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

Instrument identifier for subsequent NI-DMM nodes.

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
