    session in

    Instrument session obtained from Initialize With Options .

    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

    signal

    Type of signal to route.

    Name Description
    Start Trigger NI-RFSA routes a Start Trigger.
    Ref Trigger NI-RFSA routes a Reference Trigger.
    Advance Trigger NI-RFSA routes an Advance Trigger.
    Ready for Start Event NI-RFSA routes a Ready for Start Event.
    Ready for Ref Event NI-RFSA routes a Ready for Reference Event.
    Ready for Advance Event NI-RFSA routes a Ready for Advance Event.
    End of Record Event NI-RFSA routes an End of Record Event.
    Done Event NI-RFSA routes a Done Event.
    Reference Clock NI-RFSA routes a Reference Clock signal.
    User NI-RFSA routes a user-defined signal, specified using the signal identifier input.
    datatype_icon

    signal identifier

    User-defined signal to route.

    Specify the signal you have implemented using FPGA extensions.

    datatype_icon

    output terminal

    Terminal where the signal is exported. You can choose not to export any signal.

    Name Description
    Do not export signal The signal is not exported.
    ClkOut The signal is exported to the CLK OUT connector on the PXIe-5622 front panel.
    RefOut The signal is exported to the REF IN/OUT terminal on the PXIe-5652 and the REF OUT terminal on the PXIe-5644/5645/5646 and PXIe-5820/5840.
    RefOut2 The signal is exported to the REF OUT2 terminal on the LO. This connector exists on only the PXIe-5652.
    PFI0 The signal is exported to the PFI 0 connector.
    PFI1 The signal is exported to the PFI 1 connector on the PXIe-5622.
    PXI_Trig0 The signal is exported to the PXI trigger line 0.
    PXI_Trig1 The signal is exported to the PXI trigger line 1.
    PXI_Trig2 The signal is exported to the PXI trigger line 2.
    PXI_Trig3 The signal is exported to the PXI trigger line 3.
    PXI_Trig4 The signal is exported to the PXI trigger line 4.
    PXI_Trig5 The signal is exported to the PXI trigger line 5.
    PXI_Trig6 The signal is exported to the PXI trigger line 6.
    PXIe_DStarC The signal is exported to the PXIe_DStarC trigger line. This value is valid on only the PXIe-5820/5840.

    session out

    Reference to your instrument session passed to the next node.

    error out

    Error information.

    The node produces this output according to standard error behavior.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Tristate Output Terminals

    If you export a signal with this node and commit the session, the signal is routed to the output terminal you specify. If you then reconfigure the signal to have a different output terminal, the previous output terminal is tristated when the session is next committed. If you set the output terminal output to Do Not Export and commit, the previous output terminal is tristated.

    Tristate PXI Trigger Lines

    Any signals, except for those exported over PXI trigger lines, that are exported within a session persist after the session closes to prevent signal glitches between sessions. PXI trigger lines are always set to tristate when a session is closed. If you wish to have the output terminal tristated when the session closes, change the output terminal output for the exported signal to Do Not Export, and commit the session again before closing it.

    Tristate PFI Lines

    You can tristate all PFI lines by setting the reset input of Initialize to True or by using Reset .
