Dual Counting (
dUAL
)
A single count setting value SV is available in Dual 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.

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 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 0, and
prohibit an input signal from incrementing 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:
Each leading edge of the input signal at CP2 will increment the count present value PV by 1.

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 present value PV to 0, and
prohibit an input signal from incrementing the count PV. The
