•
Totalizing counter continues to count the present
value, regardless of whether an reset input (by the
reset key) has been made to reset the PV.
•
When totalizing count value is reset, the PV is
reset at the same time.
•
The totalizing count range is 0 to 99,999,999. If the
totalizing count exceeds 99,999,999, the count
returns to 0. If the count drops below 0, it becomes
99,999,999.
