Dashboard Error Bytes

Can anyone explain how the Master Error Code, User ERROR Code, and User Warning Code bytes work. They are in the status frame Bytes 23,24 and 25.

I have been playing with labview to test it out for possible use with our robot and I am unsure weither these are just boolean on and off values, or if they return a numeric value that corresponds to actual error messages.

Has anyone had any success using them in labview?
