A Google search of 'tripping classification' listed this as one of the first three references:

http://www.control.com/thread/1026238439#1026239000

A search of control.com using its 'Search' function (the search term was '+trip +class' without the quotes) yielded the same hit, among others.

Please use the 'Search' feature here on control.com; it's really very powerful, though it does take some practice to become accustomed to. It's pretty fast, too, not like some sites.
