Total Counting (
totAL
)
A single count setting value SV is available in Total Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily for the time set in the output pulse width parameter (
tout2
) or will be maintained ON
depending on the Output Mode selected.
CTT Counter Functions
Total Counting (total)
Counting Down (down)
Counting Down (
down
)
With the input signal OFF at input CP2, each leading edge of the
input signal at CP1 will decrement the count present value PV by 1.
Turning ON the input signal at CP2, will prohibit the input signal
at CP1 from decrementing the PV.
Input Mode:
Mode F (
F
)
The Total PV increments with each decrement of the count
present value PV. When the count present value PV counts
down to 0 both outputs 1 and 2 will turn ON. The count PV
will continue to decrement with each input signal.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count present value PV to the
count setting value SV, and prohibit an input signal from decre-
menting the count PV. The trailing edge of the “reset” signal at
RST1 enables counting to begin.
The leading edge of a “reset” input signal at RST2 will reset the
Total PV to 0, and prohibit an input signal from incrementing
the Total PV. The trailing edge of the “reset” signal at RST2
enables counting to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8.
Output Modes:
With the input signal ON at input CP1, each trailing edge of the
input signal at CP2 will decrement the count present value PV by 1.
Turning OFF the input signal at CP1, will prohibit the input signal
at CP2 from decrementing the PV.
