    session in

    Instrument session obtained from the Initialize With Channels node.

    datatype_icon

    input terminal

    Input terminal for the digital edge Start trigger.

    Valid Input Terminals

    You can specify any valid input terminal for this node. Valid terminals are listed in MAX under the Device Routes tab.

    Specifying the Input Terminal

    Input terminals can be specified in one of two ways. If the device is named Dev1 and your terminal is PXI_Trig0, you can specify the terminal with the fully qualified terminal name, /Dev1/PXI_Trig0, or with the shortened terminal name, PXI_Trig0. The input terminal can also be a terminal from another device. For example, you can set the input terminal on Dev1 to be /Dev2/SourceCompleteEvent.

    datatype_icon

    edge

    String that specifies whether to configure the Start trigger to assert on the rising or falling edge.

    Name Value Description
    Rising Edge 1016 Asserts the trigger on the rising edge of the digital signal.
    Falling Edge 1017 Asserts the trigger on the falling edge of the digital signal.

    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 used to identify the session in all subsequent NI-DCPower node calls.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
