CTT Counter Functions
Total Counting ( total )
Counting Up (UP)
Total Counting ( totAL )
A single count setting value SV is available in Total 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.
Input Mode:
Counting Up ( UP )
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. Turning ON the input signal at CP2, will prohibit the input
signal at CP1 from incrementing the PV.
With the input signal ON at input CP1, each trailing edge of the
input signal at CP2 will increment the count present value PV by
1. Turning OFF the input signal at CP1, will prohibit the input
signal at CP2 from incrementing the PV.
Output Modes:
Mode F ( F )
The Total PV increments with each count present value PV.
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 and Total 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 leading edge of a "reset" input signal at RST2 will reset the
Total PV to 0, and prohibit an input signal from incrementing
the Total 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.
