Region attribute counters are used to maintain a count of the number of times an item has been through a region. The counter is tied to a specific attribute that is either increased or decreased by increments as the item re-enters the region. You can keep track of region attribute counters using the PRT User Interface or on a graphic screen. By specifying an alarm value, you can enter a number that will generate an alarm to avoid over-processing an item.
