Last Modified: April 2, 2018

Gets the future event time on the FPGA for a given future event instance. The future event time is only valid if valid is True.

Programming Patterns

The Time node and Initialize node must execute before the Get Future Event node.

datatype_icon

niusrprio session in

Object created by the Open node and used as the session handle for the USRP RIO nodes.

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

instance

indicates that the future event time is valid.

datatype_icon

niusrprio session out

The niUsrpRio session used in all subsequent USRP RIO host nodes.

datatype_icon

future event time

Time used to schedule a future event or the scheduled future event time.

datatype_icon

valid

indicates the future event time is valid.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

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