Mode N ( n )
When the count present value PV counts down to 0, Output
2 will turn ON. 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 ).
Mode C ( C )
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 count PV will reset automat-
ically to the count setting value SV2.
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 ).
Mode R ( r )
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 is prohibited from
decrementing until the end of the output pulse time ( tout2 )
when Output 2 turns OFF and the count PV is reset automati-
cally to the count setting value SV2.
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 ).
