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
contact CY is set.
ZE
Zero
1: if QV = 0
(DWord)
QV
Current counter value in RUN mode
The pulses at channel A and
channel B are counted. 2 pulses
are counted per counting
period.
Example: 2 pulses at channel A
