Counter Reflex Blocks
At a Glance
Overview This chapter describes two counter reflex blocks that count Boolean inputs either up
or down from a preset value. The result from these counter blocks is a word value.
One counter increments or decrements on the rising edge of the operational input,
and the other increments or decrements on the falling edge of the operational input.
