In the example above, each time the operator pushes button 0001 the counter accumulated value increases by one. Note that it increases only when the button first turns on. (i.e. the off to on transition). When the accumulated value equals the preset value(i.e. 5), the C000 contacts turn on and output 0500 becomes true. When the operator pushes the reset button (0002) the accumulated value changes back to 0000.
