Mode Q (

)
When the count present value PV counts down to 0, Output 2 will turn
ON momentarily for the time set in the output pulse width parameter
(
tout2
) and the batch count present value BATCH PV will increment
by one. The count PV will continue to decrement with each input signal
until the end of the output pulse time when Output 2 turns OFF and the
count PV is reset automatically to the count setting value SV.
The leading edge of a “reset” input signal at RST1 will turn OFF Output
2, reset the count PV to the count SV, and prohibit an input signal from
decrementing the count PV. The trailing edge of the “reset” signal at
RST1 enables counting to begin.
When the BATCH PV counts up to the BATCH SV, Output 1 will turn
ON. The leading edge of a “reset” input signal at RST2 will turn OFF
Output 1, reset the BATCH PV to 0, and prohibit an input signal from
incrementing the BATCH 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.

When the count present value PV counts down to 0, Output 2 will turn
ON momentarily for the time set in the output pulse width parameter
(
tout2
) and the batch count present value BATCH PV will increment
by one. The count PV will remain at 0 regardless of additional input
signals.
The leading edge of a “reset” input signal at RST1 will turn OFF Output
