Apply Levels and Timing (G Dataflow)

Version:
Last Modified: September 14, 2017

Applies digital levels and timing values defined in previously loaded levels and timing sheets.

When applying a levels sheet, only the levels specified in the sheet are affected. Any levels not specified in the sheet remain unchanged. When applying a timing sheet, all existing time sets are deleted before the new time sets are loaded.

initial state

List of pins for which the node applies an initial pin state. If a pin is not included in the list, the pin maintains its current state.

datatype_icon

session in

Instrument session obtained from the niDigital Initialize with Options node.

datatype_icon

site list

Comma-delimited list of strings in the form of siteN , where N is the site number. If you enter an empty string, this node applies the levels and initial states to all sites.

datatype_icon

levels sheet

Name of the levels sheet to apply. Use the name of the sheet or pass the file path you use in the niDigital Load Specifications Levels and Timing node. The name of the levels sheet is the filename without the directory and file extension.

datatype_icon

timing sheet

Name of the timing sheet to apply. Use the name of the sheet or pass the file path that you use in the niDigital Load Specifications Levels and Timing node. The name of the timing sheet is the file-name without the directory and file extension.

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 NI-Digital node calls.

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
