Unmap Trigger (G Dataflow)

Version:
    Last Modified: March 3, 2017

    A deprecated function that unmaps a previous map from a trigger source line to a trigger destination line.

    This function unmaps one trigger mapping per call.

    Depending on the overload you select, this function corresponds to the following LabVIEW NXG functions:

    Overload Redirects To
    Unmap Trigger (VXI Backplane).gvi
    • VXI Unmap Trigger (VXI Backplane, All).gvi
    • VXI Unmap Trigger (VXI Backplane, Wired).gvi
    Unmap Trigger (PXI Backplane).gvi
    • PXI Unmap Trigger (PXI Backplane, All).gvi
    • PXI Unmap Trigger (PXI Backplane, Wired).gvi

    datatype_icon

    session in

    The resource to be used.

    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

    trigger source

    The source line from which to map.

    Name Value Description
    VXI/PXI TTL Line 0-7 0-7 Maps the specified VXI or PXI TTL trigger line.
    VXI ECL Line 0-1 8-9 Maps the specified VXI ECL trigger line.
    Front Panel Input 27 Maps the controller's front panel trigger input line.
    Front Panel Output 28 Maps the controller's front panel trigger output line.

    Default: VXI/PXI TTL Line 0

    datatype_icon

    trigger destination

    The destination line to which to map.

    Name Value Description
    VXI/PXI TTL Line 0-7 0-7 Maps the specified VXI or PXI TTL trigger line.
    VXI ECL Line 0-1 8-9 Maps the specified VXI ECL trigger line.
    Front Panel Input 27 Maps the controller's front panel trigger input line.
    Front Panel Output 28 Maps the controller's front panel trigger output line.

    Default: VXI/PXI TTL Line 0-7

    datatype_icon

    session out

    The resource to which a VISA session is opened.

    This output also includes the class for the session, which matches that of session in.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
