IVI Error BFFA0016: 'Attribute Already Has a Value Waiting to be Updated.' While using an IVI driver, I sometimes get the IVI error message "Attribute already has a value waiting to be updated." (Error number BFFA0016) . This error occurs intermittently. What exactly does this mean and what can I do to the instrument driver or in the code that communicates with the URL: http://digital.ni.com/public.nsf/allkb/BCB3F94F667EBBA186256A01006C6440

What Parameters in Measurement & Automation Explorer (MAX) Are Ignored When Using an IVI Specific Driver (i.e., not a class driver)? The IVI configuration utility in MAX ignores some fields when used with a specific instrument driver. Background:Users of specific instrument drivers can use the setting in MAX if they pass a logical name to the "resource name" parameter (in either LV or CVI).
