Assigns a value to a real-time sequence parameter. The value can be a constant value, data in a file, or a mapping to a channel in a system definition file. Use this VI to create parameter assignment references to use with the Create Sequence Call VI. Wire data to the Channel input to determine the polymorphic instance to use or manually select the instance.

Note You must register a DataPlugin to import from the file type it supports. Refer to the National Instruments website at ni.com/dataplugins to download DataPlugins.

Inputs/Outputs

  • cpath.png File Path —

    File Path--Specifies the path of the file from which to import values.

  • cstr.png Parameter Name —

    Parameter Name specifies the name of the parameter to assign the value.

  • cstr.png Channel Group —

    Channel Group specifies the name of the group in the import file that contains the Channel whose data you want to import. If the file type does not support groups or an equivalent container, refer to documentation for the DataPlugin or contact its creator to determine how to identify group names.

  • cstr.png Channel —

    Channel specifies the name of the channel in the import file that contains the data you want to imported. In some file types, column headers serve as channel names. For other file types, refer to documentation for the DataPlugin or contact its creator to determine how to identify channel names.

  • cerrcodeclst.png error in (no error) —

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

  • cu64.png Import Offset (0) —

    Import Offset specifies the index of the first sample in the Channel you want to import. The default is 0.

  • cu64.png Import Length (0: import rest) —

    Import Length specifies the number of values to import from the file, starting at the Import Offset index. The default, 0, specifies to import all data in the file that exists after the Import Offset.

  • ignrn.png Sequence Parameter Assignment Ref —

    Sequence Parameter Assignment Ref returns a reference to the parameter assignment. You can use this reference with the Create Sequence Call VI.

  • ierrcodeclst.png error out —

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