Overflow Value
Overflow value is the number of times the counter value exceeds the Max/Min val-
ues you specified. When the counter value exceeds Maxi- mum 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
use the "ReadOverflowFlag" library to gain readout of the over- flow 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. counter 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 Totalizer value = {|10 - 0| + 1} x| 4 |+ |10 -3| = 51
Features--Digital Output Mapping
If users want to use Digital Output function, ADAM utility is available for setting specif-
ically which module, channel or slot to receive the alarm signals.
