Application Examples

Up/Down Totalizing

Up/down totalizing is provided by a mode of the Extended
counter where pulses are either added or subtracted on
Channel A based on a direction input on Channel B. The
counter can also be programmed so that counting by Channel A
is inhibited by an input on Channel B.
