1-Stage Counting (
StA6E 1
)
A single count setting value SV is available in 1-Stage 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.

Counting Up / Command Counting Down (UdA)
Counting Up / Command Counting Down (Ud A)
With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the
count present value PV by 1.
Input Mode:
Mode F (
F
)
When the count present value PV counts up to the count setting
value SV, both outputs 1 and 2 will turn ON. The count PV
will continue to increment or decrement with each input signal.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to 0, and prohibit an
input signal from incrementing or decrementing the count PV.
The trailing edge of the “reset” signal at RST1 enables counting
to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter ( rtSr ) or DIP Switch 8.
Output Modes:
Mode N (
n
)
When the count present value PV counts up to the count
setting value SV, both outputs 1 and 2 will turn ON. The count
PV will remain at the count SV regardless of additional input
signals.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to 0, and prohibit an
input signal from incrementing or decrementing the count PV.
The trailing edge of the “reset” signal at RST1 enables counting
to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8.
With the input signal ON at input CP2, each leading edge of the input signal at CP1 will decrement the
count present value PV by 1.
