This block searches through all the faults which are causing a fault action to be true. The block begins searching at the next fault after the specified previous fault. If the previous fault input is set to the null fault the search will begin at the start of the fault list. When the block reaches the end of the fault list without finding any faults causing the action to be true it will output the null fault. This can be used as a stop condition if executing this block in a while loop to iterate through a sequence of faults.
