Overflow Value
Overflow value is the number of times the counter value exceeds the
Max/Min values you specified. When the counter value exceeds
Maximum value, the overflow value increases; When the counter value
goes under Minimum value, the overflow value decreases. Besides,
when the counter value runs beyond the range of Max/Min value, it
will continue counting from the initial value. Furthermore, if users want
to check the counter value to see if it is higher or lower than the Max/
Min value, they can run the "$aaSi7" command to gain a readout of the
overflow value.
Getting the Totalizer Value
If users want to get the actual counter value, a formula such as follows
can facilitate an easy calculation from the initial counter value,
overflow value and current counter value:
Vtol = {|Vini - Vmin (or Vmax) |+ 1} x |Vvf| + |Vini - Vcur|
V
tol : totalizer value
Vini : initial counter value
Vmin : min. couner value = 0 (fixed value)
Vmax : max. counter value = 2
32
= 4,294,967,295 (fixed value)
Vvf : overflow value
Vcur : current counter value
Example:
If the initial value =10, overflow value =4, min. value = 0, current
counter value = 3, the totalizer value could be calculated as
totalizer value = {|10 - 0| + 1} x| 4 |+ |10 -3| = 51
