The add and subtract count inputs increase/decrease the count once when the signal rises (OFF to
ON). When both inputs turn ON at the same time, neither increases/decreases the count. When the
reset input turns ON, the PV changes to 0 and count input is not accepted.
In the following example, the SV for CNTR(012) 0007 is determined by the content of CIO 0001. When
the content of CIO 0001 is controlled by an external switch, the set value can be changed manually
from the switch.
