Inputs/Outputs

  • ci32.png variable index —

    variable index specifies the index of the linguistic variable whose information you want to modify. variable index corresponds to the order in which the linguistic variable was created.

  • cu16.png input/output —

    input/output specifies whether the linguistic variable corresponding to variable index is an input or output variable.

    0Input—Specifies that the linguistic variable corresponding to variable index is an input variable.
    1Output—Specifies that the linguistic variable corresponding to variable index is an output variable.
  • ccclst.png fuzzy system in —

    fuzzy system in specifies the complete information for a fuzzy system. Wire the fuzzy system out output from another VI to the fuzzy system in input of this VI.

  • cstr.png name —

  • cdbl.png minimum —

    minimum specifies the minimum value of the linguistic variable.

  • cdbl.png maximum —

    maximum specifies the maximum value of the linguistic variable.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • c1dcclst.png membership functions —

    membership functions specifies the membership functions for the linguistic variable.

  • cstr.png name —

    name specifies the name of the membership function, or linguistic term, you want to modify.

  • cu16.png shape —

    shape specifies the shape of the function that determines the degrees of membership for the linguistic variable.

  • c1ddbl.png points —

    points specifies the values of the linguistic variable corresponding to the base and top points, in order from left to right and base to top, of the membership function. The degree of membership of the linguistic variable within the linguistic term name is 0 at the base points and 1 at the top points. Specify one point for a singleton function, three points for a triangle function, and four points for trapezoid, sigmoid, Gaussian, or user-defined functions.

  • cu32.png color —

    color specifies the color of the membership function when you view the membership function in the Fuzzy System Designer. You can wire a color box constant to this input.

  • ci32.png user-defined shape index —

    user-defined shape index specifies the index of the user-defined shape that determines the degrees of membership for the linguistic variable. This parameter is applicable only if you set shape to User-Defined. Define the user-defined shapes in the user-defined membership function shapes array in both the FL New Fuzzy System VI and the User-Defined instance of the FL Create Membership Function VI.

  • icclst.png fuzzy system out —

    fuzzy system out returns the complete information for a fuzzy system. Wire the fuzzy system out output of this VI to the fuzzy system in input of another VI.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
