While the communication thread is executed, this Driver stores in memory a list of statuses it traverses, with up to 100 items. At each reading of this Tag, the oldest status is removed from this list and displayed as a number in the respective field. The last status is kept in the value of this Tag while there is no new status. When the number of items reaches the maximum storage size, the oldest item is removed to add a new item.
