Write Key (G Dataflow)

Version:
    Last Modified: March 31, 2017

    Writes a value to a key in a specified section of the configuration data that you specify.

    This node modifies data in memory. To write data to disk, use Close Config Data.

    connector_pane_image
    datatype_icon

    use system decimal point

    Boolean specifying whether to use the system decimal separator to designate a decimal point.

    This input appears when you wire a double-precision, floating-point number to value.

    True This node uses the localized decimal separator.
    False This node uses a period as the decimal separator.

    Default: True

    datatype_icon

    section

    Name of the section in which to write the specified key.

    datatype_icon

    reference in

    Reference to the configuration data.

    datatype_icon

    key

    Name of the key to write.

    datatype_icon

    value

    Value to write to the key.

    This input accepts the following data types:

    1. Boolean
    2. Double-precision, floating-point number
    3. Path
    4. Signed 32-bit integer
    5. String
    6. Unsigned 32-bit integer

    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

    write raw string

    Boolean specifying whether to write the string without escaping unprintable and backslash (\) characters.

    If False, the VI converts any backslashes (\) to double backslashes (\\) and replaces any remaining unprintable characters in the string, such as <ESC>, with a backslash and two Hex characters (\xx). If True, the VI does not convert the unprintable characters in the string.

    This input appears when you wire a string to value.

    Default: False

    datatype_icon

    precision

    Number of digits after the decimal point.

    This input appears when you wire a double-precision, floating-point number to value.

    Default: 6

    datatype_icon

    format

    Format of the number.

    This input appears when you wire a double-precision, floating-point number to value.

    Name Value Description
    Fractional 0
    Engineering 1
    Exponential 2

    Default: Fractional

    datatype_icon

    reference out

    Reference to the configuration data.

    datatype_icon

    found

    Boolean value that indicates whether this node found the key in the specified section.

    True Found the key in the specified section.
    False Did not find the key in the specified section.
    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
