Scaling and Mapping (Map Ranges) (G Dataflow)

Version:
    Last Modified: March 31, 2017

    Creates a custom scale that scales values proportionally from a range of pre-scaled values to a range of scaled values.

    signal

    Input signal.

    This input accepts the following data types:

    • Waveform
    • 1D array of waveforms
    • Double-precision, floating-point number
    • 1D array of double-precision, floating-point numbers
    • 2D array of double-precision, floating-point numbers
    datatype_icon

    pre-scaled low

    Smallest value in the range of pre-scaled values.

    Default: -1

    datatype_icon

    pre-scaled high

    Largest value in the range of pre-scaled values.

    Default: 1

    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

    scaled low

    Smallest value in the range of scaled values.

    Default: -1

    datatype_icon

    scaled high

    Largest value in the range of scaled values.

    Default: 1

    datatype_icon

    scaled signal

    Result of scaling the input signal.

    This output can return the following data types:

    • Waveform
    • 1D array of waveforms
    • Double-precision, floating-point number
    • 1D array of double-precision, floating-point numbers
    • 2D array of double-precision, floating-point numbers
    datatype_icon

    scale

    Scaling factor.

    datatype_icon

    offset

    Offset factor.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: DAQExpress does not support FPGA devices
