Mode A ( A )
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 ). The count PV will remain at 0
regardless of additional input signals.
The leading edge of a "reset" input signal at RST1 will turn
Output 2 OFF, reset the count PV to the count setting value
SV2, and prohibit an input signal from 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 ).
