Operation
The counter output (CV) value is increased by 1 if the counter input (CU) value changes
from 0 -> 1 and the reset input (R) value is 0. If the counter output has reached its
maximum value 32767, the counter output remains unchanged.
The counter output (CV) is reset to 0 if the reset input (R) is 1.
The status output (Q) is 1 if the counter output (CV) value > preset input (PV) value.
Example:
R CU
0 1 -> 0
0 0 -> 1
1 1 -> 0
1 0 -> 1
0 0 -> 1
0 0 -> 1
CV is the previous cycle counter output value.

The counter output (CV) value is increased by 1 if the counter input (CU) value changes
from 0 -> 1 and the reset input (R) value is 0. If the counter output has reached its
maximum value 2147483647, the counter output remains unchanged.
The counter output (CV) is reset to 0 if the reset input (R) is 1.
The status output (Q) is 1 if the counter output (CV) value > preset input (PV) value.
