Counter Example 1 - Automation Direct CTT-1C-D24 Manual

Counter Example 1:

1-Stage Counting ( Stage )
Counting Up ( UP )
Using the counter feature of the CTT to count the total number of pieces in a box to signal a conveyor to
advance to the next station.
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. Or 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 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 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.
