Allows you to change or create an attribute and value for variant data.

![]() |
variant is the variant data you want to create an attribute and value for or replace a value for. | ||||||
![]() |
name is the name of the attribute you want to edit or create. If name matches an attribute, this function replaces the attribute with the value specified. If name does not match an attribute, this function creates a new attribute. | ||||||
![]() |
value is the value of the attribute. This input is polymorphic, so you can wire any data to it. | ||||||
![]() |
error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

![]() |
variant out is the variant data with new attributes. | ||||||
![]() |
replaced is TRUE if an attribute and value were replaced. | ||||||
![]() |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
