I have a test rack setup but dont have all of the I/O cards. Im trying to figure out how to make it quit going into a major fault because of a missing or mismatched card. Ive looked at the errors screen under processor properties and cant seem to find anything. This is pretty simple to do in controllogix, but i have never had to do it in the slc500 platform. There is no fault routine or anything in the logic I am testing.
