IviSwtch Send Software Trigger [SWT] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Sends a command to trigger the switch. Call this node if you pass IVISWTCH_VAL_SOFTWARE_TRIG for the Trigger Input parameter of the IviSwtch Configure Scan Trigger [SCN] Node.

    instrument handle out

    The instrument handle that you obtain from the IviSwtch Initialize Node. The handle identifies a particular instrument session.

    Default: None

    instrument handle

    The instrument handle that you obtain from the IviSwtch Initialize Node. The handle identifies a particular instrument session.

    Default: None

    datatype_icon

    error out

    Error information.

    The node produces this output 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.

    error in

    Error conditions that occur before this node runs.

    Extension Group

    This node is part of the IviSwtchSoftwareTrigger [SWT] extension group.

    IVISWTCH_ERROR_TRIGGER_NOT_SOFTWARE

    If Trigger Input is not set to IVISWTCH_VAL_SOFTWARE_TRIG, this node returns the error IVISWTCH_ERROR_TRIGGER_NOT_SOFTWARE (0xBFFA1001).

    Checking Instrument Status

    This node does not check the instrument status. Typically, you call this node only in a sequence of calls to other low-level driver nodes. The sequence performs one operation. You use the low-level nodes to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviSwtch Error-Query Node at the conclusion of the sequence.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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