Description Note
(Bit)
OF Overflow
1: if QV ≥ SH
OF=1, if the actual value is
greater than or equal to the
upper threshold value;
FB Fall below
1: if QV ≤ SL
FB=1, if the actual value is less
than or equal to the lower
threshold value;
CY Carry
1: if QV > value range
If the value range is exceeded,
the switch contact switches to
status 1 for one cycle per rising
edge detected. The function
block retains the value of the last
valid operation before the con-
tact CY is set.
ZE Zero
1: if QV = 0
(DWord)
QV Current counter value in RUN mode Integer value range:
-2,147,483,648 to +2,147,483,647
